deodorants become important to the adolescen t. With increasing hormonal activity, girls develop a more adu lt body con tour. As breasts mature, the nipples project more , and the pubic hair e.xtends to the medial thighs; the young female is estimated to be at Tanner stage 5. Ovulation may be established, and conception can occur.

Male Sexual Maturation The first sign of pubertal changes in boys is testicular enlargement in response to testosterone secret ion, which usually occurs in Tanner stage 2. Slight pubic hair is present, and the smooth skin texture of the scrotum is somewhat altered. As testosterone secretion increases, the penis, testes, and scrotum enlarge. The PHV

usually occurs during Tanner stages 3 and 4, and the voice deepens and "cracks" as the cart ilage in the larynx enlarges. A.xillary hair develops, and the eccrine and apocrine sweat glands respond to stressful or emotional stimuli. Skin surface bacteria metabolii.e secretions from the apocrine glands, and body odor develops. Gynecomastia (male breast enlargement) occurs in approximately two thirds of young males during early adolescence and may be unilateral or bilateral (Ali & Donohoue, 2011 ). This phenomenon is olien disturbing to boys, and they need considerable reassurance that the breast tissue will decrease over time. During Tanner stages 4 and 5, rising levels of testosterone cause sebaceous glands lo enlarge, and excessive sebum may result in acne. The voice continues to deepen, facial hair appears at the corners of t11e upper lip and chin, and ejaculation may occur. Nurses need to provide anticipatory guidan ce to adolescent boys regarding involuntary nocturnal emissio ns of seminal fluid ("wet dreams") and assure them that th is occu rrence is normal. By Tanner stage 5, genital maturation is co mplete, spermatogenesis is well established, facial hair is present on the sides of the face, and the male physiqu e is adultlike in appea rance. Gynecomastia significantly decreases or disappears, much to the adolescent male's relief.

Motor Development Adolescents often engage in various fo rms of motor activity, from aerobic exercise to football. Mo tor activities such as sports and dancing provide an outlet for the adolescent's energy, as well as an opportunity for competition, teamwork, and social relationships. Large muscle mass increases in adolescents, and coordination of gross and fine muscle groups improves. \'Vitll practice, adolescents become more adept at atlllerics and also at art, music, sewing. and other activities that require fine motor skills. The bones are not completely calcified until after puberty and are still fairly resistant to breaking in the young adolescent. Participants in sports activities should be grouped according to tlleir size and their sexual maturity racing rather tllan tlleir cluonologic age. A small, thin, late-maturing boy is less capable of competing with an early maturing, muscular classmate, and injuries are more likely to occur if they are grouped toge tiler. Nurses, particularly school nurses, may be helpful in assessing adolescents' growth and development and cow1seling them about sports activities in which they can succeed ratller tllan those in which they will meet with physical and psychological failure. Adolescents should have a yearly ph)rsical exam ination if participating in high school athletics ( Box 9- 1); the school nurse keeps docum entatio n of th is matter.

NURSING GOALS FOR PREPARTICIPATION SPORTS PHYSICAL EXAMINATION

Determine the athlete's fitness relative to performance requuements. Assess legal insurance requirements for partic1pa1ton. Provide wellness colllsefing and an11c1patoiy guidance.

The development of the cardiovascular pump plays an essential role in t11e adolescent's participation in gross motor activities. Cardiopulmonary capacity increases during adolescence and is relatively mature in the late adolescent. The cardiovascular pump is not as efficient in young adolescents, whose lungs are smaller. Adolescents generall)' cannot run as fast or as long as )'Oung adults. The athlete's aerob ic power, body composition, joint flexibility, an d strength of skeletal muscles determine physical fitness.

Cognitive Development Cogn itive development in nuences every aspect of adolescent psychosocial development. Cogni tion moves from concrete to abstract tllinking during the three phases ofadolescent development. According to Piaget ( 1969), formal operations, or abstract thinking, characterize the last stage of cogn itive development. Early abstract thinking encompasses inductive and deductive reasoning, the ability to connect separa te events, and the ability to understand later consequences. Abstract thinking in late adolescence is increasingly logical, and young adults are capable of using scientific reaso11ing, understanding complex concepts, and using analytic methods. Because of logical reasoning, adolescents are able to differentiate between others' perceptions and tlleir own and to view social situations from a societal perspective. In a review of adolescent cognitive development, Cromer ( 2011 ) states tllat t11e brain is still maturing during adolescence, and tllis maturational process affects cognitive and emotional processing. Increased myelinization of neurons, along with maturation of the superior temporal gy rus and the prefrontal cortex facil itate impulse control, decision-making skills, ability to unde.r sta nd consequences of alternative actions a nd prioritization. Th is aUows for increased o rga nization and problemsolving skills, as well as cr itical th inking. C ro mer (2 0 11 ) also states that poss ible hormonal influences heigh ten emotional se nsitivity and intensity, which affects adolescent stress and risk-taki ng behavior. The implica tions of this fi nd ing for nurses a re especially apparent for health teach in g. Adolescents tllink in different ways tllan adults. For example, sex education for nintll graders is quite different from that for college freshmen or adolescents with tlleir first full-time jobs. The college freshman should be able to appreciate tile later consequences of sexual behavior, whereas the young adolescent is focused on tile here and now. For example, one should ask tile nintll grader and tile college freshman how an unwanted baby will affect their lives, and compare their answers.

CHAPTER 9 For a var iety of reasons (includ ing, for example, poor comprehension ability, lack of education, and chronic substance abuse), some older adolescents remain concrete thinkers. Nurses and educators need to know the ir audiences and address them appropriately. Nurses may need to help parents learn how to communicate with their teens appropriately. Counseling a group of adolescent substance abusers may be ineffective if the consequence of their behavior is tied to the future when their thinking is in the present. A professional approach to communicating with teens includes the following: Enjoy them. Be patient and flexible. Know adolescent development; consider how a teen will look to peers. Be open to their ideas and opinions and willing to negotiate choices. Listen nonjudgmentally, keep ing criticism to a minimum. Encourage problem solv ing and mutual decision making. Ma in tain confide ntial ity. Be an advocate, bu t do no t take sides against a parent. Explore feel ings abou t hea lth ca re cho ices, an d allow for questio ns a nd a nalysis of health care op tio ns.

Sensory Development Adolescents' eyes and ears are full y developed, an d with the exception of refractive errors and occasional minor infections of the eyes, ears, and sinuses, the sensory system remains qu ite healthy. Myopia occurs in ea.rly adolescence, between ages 11 and 13 years, often requiring frequent changes in corrective lenses. Because of increased participation in competitive sports and outdoor activities, eye injuries are common in adolescence. Boys are more prone to eye injuries i:han are gi.rls. Adolescents should always be required to wear safety or protective equipment when competing in sports or participating in any activity that may compromise eye safety.

Language Development 'With the acquisition of formal operational thought and adequate intellectual capacity, adolescents are able to understand abstract concepts, process complex thoughts, and e.xpress themselves verbally. Adolescents who read extensively are generally more art iculate and have a la rger vocabula ry than those who do n o t. Social developmen t a nd self-co nfidence play a significant role in how well adolescents exp ress th emselves verbally to others. Shy, in troverted adolescents may have d iffic ulty speaking to a group or members of the opposite sex but may w rite expressively. Conversely, ext roverted, social adolescents who have n o trouble with verbal expressio n may lack the reading a nd writing skills for effective written commun ication. Computer technology has added to the adolescent's aven ues for creative expression. Adolescents are capable of expressing ideas in symbols and abstract concepts, and many enjoy interpreting or even developing complex computer programs. Computers have a symbolic language of their own that some adolescents find fascinating. Teens may become more proficient with computer technology than their parents. In addition

Health Promotion for the Adol escent

to teaching teens basic computer li teracy, many h igh schools have computer dubs where students who excel in computer languages share ideas and knowledge of computer information systems. Because of safety concerns with young adolescents using the Internet, parents need to monitor computer use and investigate whether parental controls available through some Internet access companies are appropriate for their child. Electronic or digital vehicles for communication have impacted language communication as well. Social media websites, e- mail, telephone text messaging, instant messaging, biogs, and Twitter all contribute to abbreviated communication techniques, whid1 eliminate not only grammar and sentence construction, but also word construction (e.g., using ur, for you are). Communicating with adolescents sometimes presents a challenge to parents and other adults. Although adolescents are capable of verbal expression, they are also intensely private and may not wish to divulge their thoughts a nd feelings to others. Developmentally, the verbally exp ressive 12-year-old may turn into a relatively uncommu ni cat ive 14-yea r-old. Co nflict w ith parents in creases tensio n in co mm u ni cat io n (see Pare nts \.Vant to Know box: Commu n icating with Adolescents).

PARENTS WANT TO KNOW Communicating with Adolescents Parents need encouragement to maintain open communication with their teenager while not appearing too intrusive. Inundating adolescents with questions or going through their belongings causes feelings of invasion and a lack of trust. Adolescents gel more out of discussions in which they participate than they do out of lectures and are more likely to respond positively to adults woo listen and appear interested in wN!t they have to say. Nurses who work with adolescents must develop communicatbn sldls that include assuring confidentiality, making no assumptions, remaining non)Jdgmental, and pOSing open-ended questions. Questions such as "Tel me about your plans for the future" wil glean more information than "Do you plan to go to oollege?" The queslbn "Do you live w~h your parents?" makes an assumption about the living situation that could make the adolescent feel uncomfortable. "Describe where you live and who lives with you" gives the adolescent an opportunity to discuss the living situation.

Psychosocial Development ldentity forma tion is the major develop mental task o f adolescen ce; other tasks in clude the fo rmatio n of a sexual a nd voca tional identi ty an d the ability to ema ncipa te o neself from the family or become independen t (Figure 9- 1). Ene rgy is focused within the self, and the adolescent is desc ribed as egoce ntric o r self-absorbed. Frustrated parents o~en descr ibe teenagers during this phase as self-centered, lazy, or irresponsible. In fac t, they just need time to think, concentrate on themselves, and determine who they are going to be. E ri k~on ( 1968) described the conflict of this phase of psychosocial development as identity formation versus role confusion; this phase corresponds to Freud's genital stage of psychosexual development (see Chapter 5 for information on developmental theories ).

CHAPTER 9

Health Promotion for the Adolescent

Relationships with the opposi te sex are more mature by late adolescence. Late adolescents have more realistic expectations of both themselves and those who are important to them. They devote many hours and much anxious thought to making events. such as prom night, memorable for a lifetime. Some adolescents may be left out because they are unpopular or shy or do not have the financial resources to participate in these special events.

With the freedom driving brings to the adolescent, comes responsibility. The adolescent's inexperience and risk-taking behaviors can be a lethal combination.

Computers in school and in many homes provide the ado- Although teens often have lescent with opportunities for learning, creative expression. friends of both sexes. they are communication. and entertainment.

Parents must moni- even embarrassing incidents tor their adolescent's computer connections, however, for with friends of the same sex. these networks sometimes allow access to people and activities that conflict with family values. FIG 9-1 Adolescent growth and development.

In the transitio n per iod from ch ildhood to adulthood, ado lescents try new roles and expe riment with the environment

until they find a role that fits. The phase of experimen tatio n has been termed the moratorium, meaning a period of delay gran ted to someone not yet ready to make more than a tentative commitment (Erikson, 1968). The adolescent's changing interests from year to year illustrate the lack of commitment. Parents may invest in expensive sports equipment or a musical instrument only to find it abandoned after a short time.

The peer group plays an essential role in adolescen t identity formation. Teenagers take their cues o n appearance, social behavior, and la nguage from the peer gro up. The peer group serves as a safe haven as adolescents emo tio nally move away from the family and struggle to determine who they are. The peer group valida tes acceptable behavior, and teenagers feel secure in trying on new roles with peer-group approval. Teens frequently spend al l day with friends in school and all evening rehashing the day's events over the phone or through postings

Early and middle adolescents are particularly audience co nscious and feel that they are the focus of everyone's attention. A bad hair day o r a blemish may throw the adolescent into despair. Clothing, hai rst}~es, and material possessions that are accepted by the group become the most important. Nurses cou nsel pare nts to nego tiate cho ices with teens but always consider how peers will judge the ch ild.

The Adolescent and Erikson • Identity formation ard establishment of autonomy • Acquisition of abstract reasoning leading to the following: • Analytic thinking • Problem solving • Plaming for the future Early adolescence and middle adolescence a.re the periods when teens are prone to gang formation a nd activities. Peer modeling and peer acceptance, being of the utmost importance, lead some adolescents to form gan~ that provide a collective identity and give them a sense of belonging. Peer pressure, companionship, and protecLion are the most frequently reported reasons for joining gangs, particularly those associated with violent or criminal acts. Early and late adolescence have marked developmental differences. Each age-group ha s unique reactions to the developmental tasks, whi ch are inOuenced by the adolescent's cognitive thinking. Accord ing to Piaget ( 1969), adolescent cognition is characterized by the transition rrom co ncrete operational thought to formal operat io nal tho ugh t, the ab ility to think logically and use dedu cLive a nd abstract reaso ning ( in addition to tl1is chap ter, see Chapters 5 through 8) . The acquisition of formal operational thinking allows the adolescent to recall past experience and to apply knowledge to the future by drawing logical consequences fro m a se t of observations. Adolescents are capable of using abstract symbols suc h as those derived from higher -order mathematics, making and tes ting hypotheses, and considering and argui ng philosophic issues. Problem-solving and decision-making ski lls become more highly developed, although adolescents may still be conflicted about idealism versus reality.

Early Adolescence The early adolescent ( I I to 14 years) has intense feelings about body image and the many physical changes taking place. Less confident with members of the opposite sex, early adolescents tend to group together and have best friends of the same sex. One has only to visit the local mall or a movie theater to see groups of young teens of the same sex, observing but rarely speaking to groups of the opposite sex. The early adolescent is quite egocenLric and may move from obedience to rebellion regarding parental authority. Parents are often shocked by the sudden turn of events and are hurt by the teen's rejection. Providing parent~ with a nticipatory guidance regarding age-specific developmental changes is a primary nursing function. For example, the happy-go-lucky 11-)'ear-old may turn into the shy, self-absorbed 12-year-old who seems comfortabl e o nly in Lhc presence of friends. Young teens, who are developmenlally egocentri c, fail to differentiate be.tween how others see the m a nd their own mental preoccupations, thinking ever)'O ne is as obsessed with them as they are witl1 themselves. Elk ind ( 1993) describes th is phenomenon as a reaction to the imagiliar)' aud ience. The belief in the imaginary audience is probably why you ng teens are so self-co nscious; they believe everyo ne is critica l of them, and indeed teens are quite critical of one another, espec ially those who are different. Self-conscious behavior may also be the result of the physical and emotional transitio n to middle adolescence. The early adolescent is losing the fami liar role of the child but does not ye t feel comfortable with the role of the adult. Ambivalence toward independence is common, and the teen who feels too grown up for a good-night kiss from a parent sti ll falls asleep with a favorite teddy bear. Elkind (1 993) believes that because young teens a re so audience conscious, tl1ey see themselves as unique and tell themselvesa "personal fable" that supporLS feelings ofinvulnerability. They believe bad tilings will happen to otl1ers but not to them. Adolescent suicide attempts, for example, serve as a dramatic message to others, but young teens often do not realize the final consequences of their actions.

Middle Adolescence Middle adolescence ( IS to 17 years) is often described by parents as the most frustrating period o f adolescent development. The real audience gradually repla ces the imaginary audience, and teens become even more introspective and narcissisti c. Co nformity to peer-group norms beco mes even more important, and conflicts between teenage rs and parents often escalate. Testing of limits, sulky withdrawal, a nd ove rt rebellion may occur over conflicts regard ing curfews, friends, activities, appearance, cars, and money. The adolesce nt may feel mo re secure by associating with or becoming a member ofa gang ( Box 9-3) . Nurses counsel parents to nego tiate c ho ices when possible and set limits that are perceived as reaso nable by the adolescent. Consistent disci pline and structure actually make adolescents feel more secure and assist them with decision making. With parental guidance, adolescents are able to make decisions that will result in desirable outcomes. Adults must keep in mind that middle adolescents are impulsive and impatient, however. Parental concern

SIGNS OF GANG INVOLVEMENT

• Associating with new friends while ignoring old friends. The adolescent usually will not talk about the new friends or what they do together. • A change in hairstyle or dO!hing and associating with O!her youths with the sarre style. Usually sorre ol the clothing. soch as a hat or 1acket. has the gang's colors. initials. or "street" name on it. Parents may note tanoos on the boctf. • Unexplained source ol 111lney OI ?)SSess1ons (e.g .. stereos. jewelry. cars). • Indications of lems at school. in ptblic. or at home. Youth no longer accepts parents' authority and challenges 11 frequently. • Problems at school. sud1 as failing classes. skipping school. and causing problems in class. • Fear of the police. • Unexplained signs of fighting. such as bruises. cuts. and reports of pain. • Graffiti on or around residence or possessions. • Threats from rival gang members. Sometimesa lamily member is a victim of a drive-by shooting before the family reali zes the youth is involved in a gang.

may be seen as interfe rence rather tha n gu idance and may be met with resistance and resen tment. Feelings about self-image and soc ial relationships are intense. Middle adolescence is ge nerally a time of transition from same-sex friendships to an extreme inte rest in the opposi te sex; it is also a time whe n adolescents may acknowledge homosexual feelings. The proportion of teens who are sexually experienced and sexua lly active has declined slightly, as has the teen birth rnte (Centers for Disease Control and Prevention [CDCJ, 20 l la,b ). Nurses and other health care providers cannot become complacent in response to this change in trends. The United States still has one of the highest adolescent birth rates compared to other developed countries (CDC. 2011 a). In a recent survey by the CDC (2010), 5.9% of adolescents reported initiating sexual intercourse before age 13 years, and 46% of the ninth through twelfth graders surveyed had had sexua.1 intercourse at least once. Of concern is the trend for early initiation of sexual intercourse. Sexual activity is often related to peer pressu re and selfesteem issues. Adolescents with low self-esteem are more vulnerable and are mo re apt to engage in negative risk- taking activities associated with sexuality. Decisions about sexual activity are often impuls ive a nd made with little regard to later conseque nces or prior prepa rat io n. In fact, according to the 2009 Youth Risk Behavi o r Su rveilla nce Survey (YRBSS) (C DC, 2010), of the teenagers who repo rted bein g currently sexually active, 39.9% reported they d id not use a co ndom at last intercourse. Anotl1er co ncerning trend amo ng adolescents is the increasing participation in o ral sex. Recent repo rts of nation al statistics suggest that tlie prevalence of oral sex among adolescents 15 to 19 years o ld exceeds 50% (Li ndbe rg, Jones, & Sa ntelli, 2008). Questions about ora l sexua l activity are not currently included in the YRBSS. Halpern -Fels her (2008) states that adolescents intend to have oral sex for a variety of reasons, but primarily because they believe it is more socially acceptable than vaginal

interco urse and does no t ca rry the same risks. This and other evidence-based informat io n (CDC, 2009; Lindbe rg et a l., 2008) suggest that, although many ado lescents may know that human immunodeficiency virus (HIV) and otlier infectious diseases can be contracted from engaging in oral sex, they, nevertheless, do not consider oral sex to be as risky as vagina l sex. Nurses and other health professionals who assess adolescent health status need to be more specific when interviewingadoles· cents about sexual activity. l11e question of whether an adolescent is sexually active is no longer sufficient; questions should be directed toward assessing participation in various specific types of sexual activity as well as the method of barri er protection used. Nurses may help by providing accurate information to assist adolescents in making appropriate sexual choices. Parents need encouragement to maintain open commun ication and guide teenagers in sexual decision making. Providing parental guidance about sexual behavior is not easy du rin g middle adolescence, when privacy is o f extre me impo rtance and commun ication with parents tends to decrease. In add iti o n, some parents may find sexual behavior a d iffi cult top ic to discuss and often avoid talking with teens about sexual issues altogether.

NURSING QUALITY ALERT

Elements of Adolescent Care Nurses working with middle adolescents need 10: • Be approachabl e • Maintain objectivity • Encourage confidence • Sup?)rt parental authority • Be a child advocate while not coming between adolescents and their parents • Encourage the family to work as a rrutually respectful unit

Vocational Exploration. In the initial stages of establishing a vocational identity, adolescents are more likely to experience role confusion and have unrealistic expectations of themselves. Some adolescents identify a role that holds their interest, whereas others experiment with many roles, moving quickly from one role to another. Overidentification with glamorous roles takes precedence over reality and is enriched by da)'dreams and fantasy. A JS -)1ear-old girl may spend time witl1 her friends describing her future as a popular med ia sta r while failing to fold the laundry or do the dishes. During middle adolescence, so me teens acqu ire part-time jobs and identify vario L1s ski lls and interests. Part-tim e jobs are often a source of in come for material possessio ns and activities not provided by pare nts. Such experiences help adolesce nts set real istic expectations about work, become more independent, and develop self-esteem. Those who a re successful in the wo rking world demonstrate a se nse of responsibili ty a nd tend to have more positive soc ial interactio ns. I lowever, some adolescents may allow work to interfere with educatio na l activity and have difficulty setting priorities. School nurses, in collaborntion with parents and teachers, are in an excellent position to identify working students and assist them in sening realistic guidelines for work and education.

CHAPTER 9

Late Adolescence (18 to 21 Years) Late adolescence is characterized by theabilityto think abstractly, conceptualize verbally, and express thoughts and feelings about various aspects of life. Late adolescents tend to be idealistic about love, social issues, ethics, and li festyles until their experiences modify their beliefs. Conformity becomes less important as teens progress through late adolescence. \'Vith the development of a unique identity, self-esteem increases, and adolescents are able to resist group pressure if it is not in their best interest. Interactions with parents are less turbulent unless values clash, and relationships with both friends and family are maintained. Emancipation (leaving home) is a major issue; late adolescents prepare themselves to meet this task through education or vocational training. Identifying realistic career goals is important, but many adolescents are not yet ready to make lifelong commitments. Cha nging ca reer goals is not wKommon, but the nurse should watch for those adolescents who have set no career goals, who demonstrate apathy about the future, and who appear committed only to the p resent. Boredom and apathy are often S)'ll1ptoms of o greater problem: depression. Social relationsh ips a re mo re matu re, although partner selection often conti nues to fluctuate. Friendsh ips developed in late adolescence may last a lifetime, and expectations of friends and loved ones become more realistic and less self-serving. The ability to consider others' needs increases, and recognition of societal needs is more apparent as the adolescent moves from adolescence to ad ult hood. Failure to achieve identity formatio n may leave adolescents in role confusion and inlpede the successful mastery of the tasks of young adu lthood. A positive ego identity depends on the adolescent 's ability to accept the past, learn from experience, and become engaged in the future. Most adolescents move through the identity versus role confusion stage of development with minimal difficulty.

Moral and Spiritual Development Children develop moral reasoning in a sequential manner, as described by American psychologist Lawrence Kohlberg ( 1964}. As adolescents move from con crete to analytic thinking, they advance to Kohlberg's stage 4 conventional level or Kohlberg's stage 5 postconventional level of moral development. Adolescents who remain co nc rete thinkers ma)' never advance beyond Kohlberg's stage 3 of moral reason in g: conformity to please others mid avoid pun ish ment. The teenager's sense of justice is developed through interpersonal relatio nships with peers, fam ily, and other adult role models. Behaviors that a re modeled and rewarded, such as help ing the less fo rtunate and showing loyalty to friends, contribute to the development of a conscience, which operates as a moral guide for subsequent behavio r. The middle to late teenager can appreciate that stealing from others is wrong regardless of whether one is caught and punished. Adolescents and young adults develop a respect for law and order and a society-maintaining orientation ( Kohlberg's stage 4). Young adults may even advance to the societal-perspective stage (Kohlberg's stage 5). which honors the moral rules of right and wrong, contractual agreements, majority opinion, and overall utility or the greatest good for the greatest number (see Chapter 5).

Older adolescents and yo ung adults question the values of family and society and cha llenge existing moral codes before integrating their experiences and beliefs into a personal moral framework. Once the moral framework is developed, interpersonal relationships tend 10 be with those whose va lues and beliefs are similar. Young adolescents in the stage of concrete operational thought are able to think logically. In this stage, cliildren deal well with the observable but also begin to see other points of view and examine what they have learned. lbe young adolescent will accept religious teaching and examine how religious concepts relate to everyday life. Young adolescents are especially inclined to look to God for guidance when troubled. Middle to late adolescents are capable of analytic thought and may begin to question the religious affiliation of the family, much as they question other family values. Older adolescents may explore different kinds of religion and sha re religious activities wid1 the peer group. Evidence suggests that sp irituality has a positive effect on heald1- related qual it)' of life in adolescents (Cotto n, Tsevat, & Yi, 2007). Spiritual ity ma)' also be protective fo r both physical and emotional well -being ( Rub in, Dodd, Desai, et al., 2009). As part of providing holistic nursing care, nu rses need to include an assessment of spiritual bel iefs and values when wo rking with adolescents and in co rporate these values in nursing in terve n ti o us.

HEALTH PROMOTION FOR THE ADOLESCENT AND FAMILY Adolescence is generally a period of wellness. Young people may seek health care for school or sports physicals, skin conditions (acne, contact dermatitis). acute minor illnesses (colds, flu). conditions related to sexuality (birth control, pregnancy, sexually transmitted diseases [STDsl}, and the management of chronic illness (diabetes, epilepsy). I lealth promotion and disease prevention are achieved through adequate nutrition, rest, balanced exercise, and proper immunization against disease. During well visits for health promotion, adolescents confer privately with die nurse and tl1e health provider; separately, parents are asked about any co ncerns tl1ey might have. Confidentiality is often an issue when adolescents are seen in the health care setting. Nurses should enco urage adolescents to involve their parents, but adolescents frequent!)' ask d1at communication be kept confidential. The adolescent must understand that the nurse will respect th is confidential ity unless the in formation shared suggests a potentially life- th reaten ing danger either to the adolescent or to others.

CHAPTER 9

Health Promotion for the Adolescent

Adolescents need to be directly asked questions about their health. These include questio ns about d iet and exercise, sexual risk behavior, substance use, preventive safety measures (e.g., seat belt, bicycle helmet, protective sports equipment), violence, peer and fan1ily relationships, and emotional health (AAP Committee on Adolescence, 2008 ). Screening tools are available that perform an adolescent assessment in an organized manner. Guidelines for Adolescent Preventive Services (GAPS) is an assessment program that looks at parenting, development, drugs, sex, learning problems, depression, abuse, safety, and diet and fitness. GAPS is a comprehensive packet of services that includes screening and preventive services {American Medical Association, 1997). 11lere are specific screening tools that assess for emotional and mental health issues. One of these is the Diagnostic Predictive Scales-8 (DPS-8), which is a questionnaire about mental health issues including su icide (ideation, attempts), phobias, general anxiety, substance use, and depressive symptoms {Husky, Miller, McGuire, et al., 2011 ). Questionnaires ca n be adm inistered befo re the adolescent comes to the provider or in th e provider's o rfi ce, eith er by paper and pencil or by computer ( Husky et al., 20 I I). So me providers pub! ically display their poli cy o n co nfide ntiality, always underlin ing the need to share info rmatio n o nly if someo ne is in danger. Issues related to the time necessa ry for an adequate interview may arise in the current managed care e nviro nment. Nurses should be knowledgeable about co mmunicating with adolescen ts and aware of when referral is warranted. Access to regular quality health ca re for adolescen ts has become an increasing issue of concern because of its importance to the prevention of illness related to adolescent risk behavior (AAP Commiuee on Adolescence, 2008 ). Regular health promotion visits to a provider during adolescence facilitates comprehensive health screening, preventive intervention, counseling, and referral. Many adolescents and their parents perceive the yearly sports physical as being sufficient. However, this physical, often performed by a school physician, is not comprehensive enough to identify subtle problems, nor is it likely to provide time for confidential communication of adolescent concerns to the provider ( AAP Committee on Adolescen ce, 2008). For this reason the AAP Committee on Adolescence (2008) recommends tlrnt access to comprehensive health care for adolescents be widely available in a variety of venues that include school-based health cl inics, physicians' offices, community or public health cl in ics, and hosp ital s. In addit ion, the Comm ittee reco mm ends o ffering assurance of confidential ity, comprehensive serv ices, ca re that is culturally and ethn ically relevant, and health insurance coverage for all adolescents (AAP Committee o n Adolescence, 2008).

Nutrition during Adolescence The accelerated growth (in linea r heigh t, weight, and muscle mass) and sexual maluration during adolescence increase teenagers' nutritional needs, including needs for protein, calories, zinc, calcium, and iron. Periods of intense growth require increased caloric intake, and the adolescent appears constantly hungry. Snacks and regular meals need to contain adequate nutrients to meet the body's anabolic needs. Adolescents are

generally interested in nutrition and the effect food has on their bodies. Teenagers tend to be concerned about their weight, complexion, sexual development, and acceptance by their peers. These issues, together with the adolescent's growing independence, can have nutritional impl ications.

Age-Related Nutritional Challenges The adolescent's food hab its a re influenced by many factors (Box 9 -4). Unfortunately, th is happe ns at a time when the body has greater nutritio nal needs. Boys tend to have fewer nutritio nal deficiencies than girls because they take in more food and are less likely to be dieting. Soft dr in ks freq ue ntly replace milk. Fast foods and low- nutrient "junk foods" sometimes become the mainstay of the adolescent 's d ie t. The soc ial a~pect of food consumption gains importance, and adolescents may p refer to eat meals with peers at social gatherings and restaurants of their choice. Parental supervision of mea ls declines as the adolescent spends more time away from home and engages in ext racurricular activities with peers.

Nutritional Guidance for the Adolescent The nurse needs to understand growth and development to be successful in cowlseling adolescents and their parents about nutrition. Adolescents' increasing need to be independent and make their own d1oicesshouldguide the nurse in teaching nutrition. The adolescent should always be involved in the planning. The nurse should assess the adolescent's present diet and determine habits and eating patterns. The assessment should elicit how often the adolescent eats food from the differen t food groups and what foods the adolescent does not eat. On the basis of tllis information, nutritious foods for meals ca n be identified and a plan developed. In general, the U.S. Department of Agriculture {USDA) (2011) recom mends 1600 to 1800 calo ries per day for adolescent girls and 1800 to 2200 ca lories/day for adolescen t boys, with foods coming from a variety of groups-whole grains, fruits and vegetables, dairy, and protein (plant and animal). Adolesce nts should drink at least three cu ps of milk a day and limit fats to 25% to 35% of total daily calo ries co nsumed. Adolescents need calcium and vitamin D to prevent future osteopo rosis, and adolescent girls require adequate iron and folic acid ( 400 mcgl day from supplements or folic acid-fo rtified foods) (USDA, 20 11). Recently, the use of so-called energy drinks has increased in the adolescent population. These drinks contain large amounts of caffeine, along ,.;jth glucose and other, non-regulated, substances. The AAP Committee on Nutrition and the Council on

prevalent during the adolesce nt years: gingivitis, malocclusion, and dental trauma. Gingivitis is the inflammation and breakdown of the gingival epitlieli um; the gums appear pale and swollen and bleed easi ly. Increased hormonal activity at the time of puberty, diets nigh in sugar and simple carbohydrates, and the use of dental braces and appliances that make cleaning less effective are thought to contribute to the development of gingivitis.

Sports Medicine and Fitness (20 11 ) have stated that energy drinks are inappropriate fo r children and adolescents because they can contribute to obesity as well as other health problems related to calfeine ingestion and excessive glucose. The nurse can a lso assist the adolescent by pointing out nutritious fast foods and snacks. An awareness of nutritious fast foods can also aid the adolescent in meal selection. Many fast-food chains have salads with nonfat or low-fat dressings, grilled chicken sandwiches, pasta, and nonfat yogurt. Fat and salt contents have been reduced, and vegetable fats have replaced animal fats at some restaurants. Adolescents should be guided to mix an occasional hamburger and fries with a regular selection of more nutritious foods. Permission should be given to eat foods that may be untraditional at a particular meal, such as pizza for breakfast. Many adolescents decide to follow a vegetarian diet during their teen years. Several dietary organizations have suggested that a vegetarian diet, if correctly followed, is health)' for this population because the low-fat aspect of the diet can prevent future card iovascular problems (Stettle r, Bhatia, Parish, et al., 2011). If an adolesce nt wish es to follow a vegetarian diet, the nurse can assist with phmn ing food choices that will provide sufficient calo ries and necessary nutrients. The focus is on obtaining sufficie nt calo ri es for growth and energy through a variety of fruits a nd vegetables, whole grains, nuts, legumes, seeds, tofu, and soy milk; so me vegeta rians choose to eat eggs and dairy products as well (S tet tler et a l., 2011 ). As with any adolescent, nurses need to advise adolescents who follow a vegetarian eating plan to avoid low- nutrient, high -fa t foods. Body image is of particular importance to adolescents. The media reinforce the belief that " thin is in." Adolescents hold themselves to standards set by the entertainment and advertising worlds, which emphasize fitness, glamour, and se.'.=~~~

CHAPTER 12 of cytoplasm, plus the other 23 ch romosomes, goes into a tiny, nonfunctional polar body that soon degenerates. At ovulation, thesecondaryoocyte begins dividing again (second meiotic division) to form a mature ovum. The 23 chromosomes duplicate themselves in the second meiotic division, but half of the duplicated chromosomes will be discarded if fertilization occurs. TI1e second meiotic division is prolonged, and the mature ovwn remains suspended in metaphase, the middle part of cell division. lffertilization occurs, the second meiotic division is completed, resulting in a mature ovum containing 23 chromosomes and a second tiny polar body containing the 23 discarded duomosomes tl1at degenerates. If the ovum is not fertilized, it does not complete the second meiotic division and degenerates. In oogenesis, one primaryoocyte result~ in a single mature ovum. When released from the ovary, the mature ovum is surrounded by two la)1ers-the 1.ona pellucida and the cells of the corona radiata. These layers protect the ovum and prevent fertilization by more tlian o ne spe rm. Fo r fertili7..ation to occur, the spe rm must penetrate these two layers to reach the ovuni 's cell nude us.

Spermatogenesis Spemiatogene~is, o r formation of spe rm,

begin s d uring puberty in the male (Figure 12- I, B). Primitive spe rm cells (spermatogonia) develop during fetal li fe and begin multiplying by mitosis during puberty. Unlike the female, the male produces new spermatogonia that can mature into sperm throughout h is li fetime. Although male fertility gradually declines with age, men can father children in their 50s, 60s, and beyond. Each spermatogonium contains 46 paired chromosomes, like other body cells. In the mature male, a spermatogonium enlarges to become a primary spermatocyte, still containing all 46 chromosomes. The first meiotic division forms two secondary spermatocytes and reduces the number to 23 unpaired chromosomes: 22 autosomes and I sex chromosome, either an X or a Y. Ead1 secondary spermatocyte divides again in the second meiotic division LO form two spermatids. Therefore half of the four spermatids that result from the two meiotic divisions of the spermatogonium carry an X chromosome and half c.arry a Y. The spermatids gradually matu re into sperm. The gamete from a male determines the sex of the new baby. If all X- bearing spermatozoon fertilizes the ovum, the baby is a girl. lf a Y- bear ing spermatozoo n fertilizes the ovum, the baby is a boy. Th e mature sperm has th ree sectio ns: a head, a middle portio n, a nd a tail ( Figure I 2·2) . The head is almost entirely the cell nucleus. The head co nta in s the male ch romosomes that jo in the ch romosomes of the ovum. The middle po rtio n supplies energy fo r the ta il's wh ipl ike actio n. The moveme nt of the tail p ropels the sperm toward the ovum.

Conception and Prenatal Development

although the exact durat ion of its viab ility is unknown. Most sperm survive no mo re than I to 2 days alt ho ugh a few may remain fertile in the woman's reproduct ive tract up to 80 hou rs (Blackburn, 2013; Carlson, 2009).

Preparation for Conception in the Female Before ovulation, several oocytes begin to mature under the influence of follicle-stiniulating hormone (FSH ) and luteini7..ing hormone (LH) from tl1e woman's anterior pituitary gland. Eadi maturing oocyte is contained in a sac witliin the ovary called the graafian follicle, which produces estrogen and progesterone to prepare the endometrium (uterine lining) for a possible pregnancy. Eventually one follide outgrows the others. The less mature oocytes permanently regress.

Release of the Ovum Ovulation, or release of tl1e ovwn, occu rs about 14 days before a woman's next menstrual period would begin. The follicle develops a thin spot on the su rface of the ova ry and ruptures, releasing the mature ovw11 with its surround ing cells on the surfu ce o f the ova iy. There the collapsed foJJkle beco mes the corpus luteum, which maintains the high estrogen mid progestero ne secretio n necessary to make final preparatio n of the uterine lin ing fo ra fertiljz.ed ovum.

Ovum Transport Released o n the surface of the ovary, the mature ovum is p icked up by the fimbriated (fringed) ends of the fallopia n tube near the surface of the ovary. The ovum is transported through the tube by muscular action of the tube and movement of cilia within the tube. Fertilization normally occurs in the distal third of the fallopian tube, near the ovary. The ovum, fertilized or not, enters the uterus about 3 days after its release from the ovary.

Preparation for Conception in the Male The male preparation for fertilizing tl1e ovum consists of ejaculation, movement of tl1e sperm in tl1e female reproductive tract, and preparation of tl1e sperm for actual fertilization.

CONCEPTION Conception requires correct timing between release of a mature ovwn at ovulation and ejaculation of enough healthy, mature, motile sperm into the vagina. The ovum may have the capacity to be fertilized no longer than 24 hours after ovulation,

CHAPTER 12

Conception and Prenatal Development

Ej ac ul ati on Expulsion of se men from the penis is ejac ulation . When a male ejaculates during vaginal inte rco urse, 35 to 200 million sperm are deposited in the upper vagina and over the cervix (Blackburn, 2013; Hall, 20 11 ; Jones, 2009b). The sperm are suspended in seminal fluid, which nourishes and protects them from the acidic vaginal environment. To hold the semen deeply in the vagina, the seminal fluid coagulates somewhat after ejaculation. The sperm are relatively immobile for about 15 to 30 minutes until other sem inal enzymes dissolve the coagulated fluid and allow the sperm to begin moving upward through the cervix.

Transport of Sperm in the Female Reproductive Tract Whiplike movem ent o f the tails of spermatowa propels them through the cervix, uterus, and fallopian tubes. Uterine contractions induced by prostaglandins in the sem inal fluid enhance movement of the sperm toward the ovum. Onl)' sper m cells enter the cervix. The sem inal flu id remains in the vagina. Many s perm a re lost along the way. Some are d igested by vaginal enzymes and phagocytes in the female rep roductive tract, whereas others move into the wro ng tube o r past the ovum and out into the periton eal cavity. On ly a few hundred reach the fallopian tube where the ovum waits.

Preparation of Sperm for Fertilization Sperm are not immediately ready to fertilize the ovum when they are ejaculated. While making the trip to the ovum, the sperm undergo changes (capacitatio11) that enable one to penetrate the protective layers surrounding the ovum. During capacitation, a glycoprotein coat and seminal proteins are removed from the acrosome (tip of the sperm head). After capacitation, the sperm

look the same but are more active and can better penetrate the corona radiata and zona peUucida that surround the ovum. The sperm that reach the ovum release an enzyme (hyaluronidase) to digest a pathway through the coro na radiata and zona pellucida. Their tails beat harder to propel them toward the center of the ovum. Eventually, one spermatozoon penetrates the ovum.

Fertilization Fertilization occurs when one spermatozoon enters the ovum and the two nuclei containing the parents ' chromosomes merge ( Figure 12- 3).

Entry of One Spermatozoon into the Ovum Entry of a spermatozoon into the ovum has two results: Changes in the ?..Ona pellucida su rrounding the ovum prevent other sperm from entering. The ovw11, wh ich has been suspended in the middle of its second meiotic div ision, co mpl etes meiosis. The resul ts are a nucl eus with 23 ch romosomes and exp ulsion of a seco nd no n func tional pola r body. The mat ure ovum now con tains 23 w1paired chromoso mes, 22 autosomes, and 1 X chromosome in its nucleus.

Fusion of the Nuclei of Sperm and Ovum Fusion of the nuclei of th e sperm and ovu m begins when the sperm enters the ovum. The sperm head enlarges, and the tail degenerates. The nuclei of the gametes move toward the center of the ovum, where the membranes surro unding their nuclei touch and dissolve. The 23 chromosomes from the sperm mingle with the 23 from the ovum, restoring the diploid number to 46. Fertilization is complete within 24 hours, and cell division of the zygote can begin when the nuclei of the sperm and ovum unite.

CHAPTER 12

PRE-EMBRYONIC PERIOD The pre-embryonic period is the first 2 weeks after conception. Figure 12-4 illustrates the period from fertilization through implantation.

Initiation of Cell Division The zygote divides into two cells, then four, then eight cells while in the fallopian tube. Up to the 16-cell stage, the cells become smaller with each division, so they occupy about the same amowlt of space as the original ovum. \Nhen the conceptus (fertilized ovum) is a solid ball of 12 to 16 cells, it is called a morula because it resembles a mulberry. The outer cells of the morula secrete fluid, creating a sac of cells (the blastocysl) that has an inner cell mass within the sac. The inner cell mass of the blastocyst develops into the fetus. Part of the outer layer of blastocyst cells develops into the placenta and fetal membranes.

Entry of the Zygote into the Uterus The con cep tus enters the uterus abo L1t 3 to 4 days after conception, when it co ntains abou t 100 cel ls. It lingers in the uterus another 2 to 4 days befo re begi nning implantation. The endo metrium, now called the decid1111, is in the sec retory phase of the reproductive cycle, J 'h weeks befo re the woma n would begin her menstrual period. The endo metrial glands are secreting at their maximum, provid ing rich fluids to nourish the co nceptus before placental circulatio n is established. The endometrial spiral arteries are well developed in the secretory phase, providing easy access for developing the placental blood supply.

Implantation in the Decidua The conceptus carries a small supply of nutrients for early cell division, but implantation (nidntion) at the proper time and

Conception and Prenatal Development

217

loca tion in the uterus is c rucial for continued developmen t. Complete implantation is a gradual process that occurs between the 6th and 10th days. Embryo nic st ruct ures co ntinue developing during implantation.

Maintaining the Decidua Implantation and survival of the concept us are critically dependent on a continuing supply of estrogen and progesterone to maintain the decidua in the secretory phase. The zygote secretes human d10rionic gonadotropin (hCG) to signal that a pregnancy has begun. With continued hCG production by the conceptus, the corpus luteum continues to secrete estrogen and progesterone ralher Lhan regressing.

Location of Implantation The conceptus must be in the right place at the right time for normal implantation to occur. The site of implantation is important because that is the place that the placenta develops. Normal implantatio n occu rs in the upper uterus (fundus). The upper uterus is the best a rea fo r implantation and placen tal development for three reaso ns: The upper uterus is richly supplied with blood for optimal fetal gas exchan ge

    The lower respiratory tract begins growth as a branch of the upper digestive tract, which is tubular at this time. Gradually, the esophagus and trachea separate completely. The trachea branches to form the right and left bronchi. These bronchi in turn branch to form the three lobes of the right lung and tw·o

    Jobes of the left lw1g. Continued branching of the bronchi eventually forms the terminal air sacs (alveoli). The alveoli proliferate and become surrounded near term by a rich capillary network that allows oxygen and carbon dioxide exchange at birth.

    Fifth Week The head is very large because tJie brain grows rapidly during the 5tJ1 week. 111e heart is beating and developing four chambers. Upper limb buds are paddle shaped, with notches between the fingers. Lower limbs are also paddle shaped, but the area between the toes is less defined tJ1an the division between the fingers.

    Sixth Week The head is prom inent beca use of rap id development and is ben t over the chest. The heart ret1ches its final fou r-chambered form. Upper and lower ex trem ities co n tinue to become more defined. The eye continues to develop, and the beginn ing of the external ear is apparent as six small bumps nea r each side of the neck. Facial development begins with eyes, ea rs, and nasal pits widely separated, aligned with th e body walls. Gradually the embryo grows so that the face comes together at the midline.

    Seventh Week Growth and refinement of all systems occur. The face is now hurnan looki11g. The eyelids begin to grow, and the extremities

    CHAPTER 12 become longer and better defined. The trunk elonga tes and straightens, although a C-shaped sp inal c urve remains at b irth. During the embryo nic period, the intestines grow faster than the abdominal cavity. The relatively large liver and kidneys also occupy much of the abdomina l cavity. Therefore most of the intestines are contained within the wnbilical cord while the abdominal cavity grows to accommodate them. By 10 weeks, the abdomen is large enough to contain all its normal contents.

    Eighth Week The embryo has a definite human form, and refinements to all systems continue. 111e ears are low-set but are approaching their final location. The eyes are pigmented but not fully covered by eyelids. Fingers and toes are stubby but well defined. The external genitalia begin 10 differentiate, but male and female characteristics are not distinct until after the I 0th week.

    FETAL PERIOD Beginnin g 9 weeks after co nceptio n and ending with birth, the rapidly dividing cells become a fetus. Dramatic growth and refinemen t in the st ruct ure a nd function of all organ systems occur during the fetal period. Teratogens may damage already formed structures but are less likely to cause major structural alterations. The central ne rvo us system is vulnerable to damaging agents through th e entire pregnancy. Figure 12- 6 illustrates growth and development during the feta l period.

    Weeks 9 Through 12 At the beginning of this period, the head is large, about half the total length of the fetus. The body begins growing faster than the head. The extremities approach their final relative lengths, although the legs remain proportionally shorter than the arms. The first fetal movements begin but are too slight for the mother to detect 111e face is broad, with a wide nose and widely spaced eyes. The eyes dose al 9 weeks and reopen at 26 weeks after conception. The ears appearlow-set because the mandible is still small. The intestinal contents that were partly contained within the umbilical cord enter the abdomen as the capacity of the abdominal cavity catches up with their size. Blood formation occurs primarily in the liver dur in g the 9th week but shifts to the spleen by the end of the 12th week. The fetus begins producing urine during this period, excreting it inl'o th e amniotic sac as part of amniotic flu id. Inte rnal differen ces in males and females become apparent in the 7th week. External genitalia look similar until the end of the 9th week. By the end of the 12th week, the fetal sex can often be determined by the appeara nce of the external genitalia on ultrasowid.

    Weeks 13 Through 16 The fetus grows rapidly in length, so the head becomes smaller in proportion to the total length. Movements strengthen, and some women, particularly those who have been pregnant before, are able to detect them. Fetal movements produce the experience of q11icke11i11g.

    Conception and Prenatal Development

    223

    The face looks human because the eyes face fo rward. The external ears approach their final pos ition, in line with the eyes.

    Weeks 17 Through 20 Fetal movements feell ike fluttering, or "butterflies." Some women may not recognize these subtle sensaLions for what they are. Changes in the skin and hair are evident. Vemix caseosa, a fatty, dleeselike secretion of the fetal sebaceous glands, covers the skin to protect it from constant exposure to amniotic fluid. Lanugo is fine, downy hair that covers the fetal body to help the vemix adl1ere to tl1e skin. Both vernix and lanugo diminish as the fetus reaches term. Eyebrows and head hair appear. Brown fat is heat -producing fot deposited on the back of the neck, behind the sternum, and around the kidneys. Brown fat helps the neonate maintain temperature stability after birth (see Figure 21-3).

    Weeks 21Through24 The fetus continues growing a nd ga ining weigh t but is th in and has little subcu tan eo us fat. T he skin is translucent and looks red because the cap illaries are close to its fragile surface. The lungs begin to produce s11rfacta111, a surfa ce-active lipid that makes it easier fo r the baby to b reathe afte r birth. Surfactant reduces surface tens io n in the Jung alveoli a nd keeps them from collapsing with each b reath. The capillary network sur rounding the alveoli is increasing but is still very immature, a lthough some gas exdlange is possible. If born at the e nd of this period, the baby may survive. However, multiple complications related to immaturity of all systems are likely, and the survivor has a high risk for permanent disability.

    Weeks 25 Through 28 With maturation of tl1e lungs, pulmonary capillaries, and central nervous system, the fetus is more likely to survive if born after 24 weeks. The fetus becomes plumper and smoother skinned as subcutaneous fat is deposit·e d under the skin. The skin becomes less red. The eyes, closed since 9 weeks, reopen. Head hair is abw1dant. Blood formation shifts from the spleen to the bone marrow. During early pregnanC)'• the fetus floats freely within the anmiotic sac. The fetus usually assumes a head-down position during this time, however, for two reaso ns: T he uterus is shaped like an in verted egg. The shape of the fetus in flexion is similar, with tl1e head as the small pole of the egg sh ape, and with the b uttocks, flexed legs, and feet as the large r pole. The fetal head is hea vier than the feet, and gravity causes the head to d ri ft dow nward in the pool of amniotic fluid.

    Weeks 29 Through 32 The skin is pigmented accordi ng to race and is smooth. Larger vessels are visible over the fetal abdome n, but sma ll capillaries cannot be seen. Toenails are present, and fingernails extend to the fingertips. The fetus has more subcutaneous fat, rowiding the body contours. If the fetus is born during this period, chances of survival are good with neonatal intensive care.

    FIG 12-6 Fetal development from 9 w eeks of fertilization age through 38 weeks of fertiliza tion age. Gestational age, measured from the first day of the last menstrual period, is about 2 weeks longer than the fertilization age.

    CHAPTER 12

    Weeks 33 Through 38 Growth of all body systems continues until birth, but the rate of growth slows as full term approaches. The fetus is mainly gaining weight. The pulmonary system matures to enable efficient and unlabored breathing after birth. The well -nourished term fetus is rorund, with abundant subcutaneous fat. Lanugo may be present over the forehead, upper back, and upper arms. Vernix may remain in major creases, such as the groin and axillae. The testes are in the scrotum. Breasts of both male and female infants are enlarged, and breast ti.o;sue is palpable beneath the areola and nipple. Full term ranges from 36 to 40 weeks of fertilization age, or 38 to 42 weeks of gestational age. Because conception occurs about 2 weeks aflerthe first day of the last menstrual period, the fertilization age, used in this chapter, is about 2 weeks shorter than the gestational age. Gestational age, however, is most commonly used in practice because the last menstrual period pro,~des a known marker, whereas most women do not know exact!)' when the)' conceived.

    AUXILIARY STRUCTURES Three auxiliary structures develop simultaneously with fetal growth to sustain the pregnancy and permit normal prenatal development: the placenta, the umbilical cord, and the fetal membranes.

    Placenta The placenta is a thick, disk-shaped organ (Figure 12-7). Its major functions are ( I) metabolic, (2) transfer of substances between mother and fetus, and (3) endocrine. The fetal side is smooth, with branching vessels covering the membrane covered surface. The maternal side is rough where it attaches to the uterus (see Figure 16- 14). 111e umbilical cord is normally inserted on the fetal side of the placenta, near the center. It may insert off-center or even out on the fetal membranes, however. Figure 12-8 (p. 227) illustrates the normal insertion and variations from normal. The placenta is larger than the embryo or fetus during early pregnancy and appears to be low lying on ultrasound. The fetus grows faster than the placenta so that the placenta is about one sixth the weight of the fetus at the end of a ter m pregnancy and is implanted in the upper uterus ( Benirschke, 2009b).

    Conception and Prenatal Development

    225

    The decidua capsularis, wh ich overlies the embryo and bulges into the uterine cavity as the embryo and fetus grow. The decidua parietal is, which lines the rest of the uterine cavity. By about 22 weeks of gestation, the decidua capsularis fuses with the decidua parietalis, filling the uterine cavity. Citculation in the Maternal Side. Exchange of substances between mother and fetus occurs within the it11ervil/011s space of the placenta. While in the imervillous space, maternal blood is briefly outside her circulatory system. About 150 ml of maternal blood is contained within the intervillous space, and it is changed about three or four times per minute. Maternal blood enters the intervillous spaces through 80 to 100 spiral arteries in tl1e decidua. After the oxygenated and nutrient-bearing maternal blood washes over the chorionicvilli containing fetal capillaries, it returns to the maternal circulation through the endometrial veins for elim inati on of fetal waste products.

    Fetal Component Development The fetal side of the placenta develops from the outer cell layer ( trophoblast) of the blastocyst at the same time that the inn er cell mass develops into the embryo and fetus. The primary chor ion ic villi are the initial structures that eventually form the fetal side of the placenta. Circulation in the Fetal Side. 13lood is circulated to and from the fetal side of the placenta by the fetal heart. The umbilical cord contains two umbilical arteries that spiral around one vein to transport blood between the fetus and placenta. The chorionic villi are bathed by oxygen -rich and nutrient-rich maternal blood in the maternal intervillous spaces. Each chorionic villus is supplied by a tiny fetal artery carrying deoxygenated blood and waste products from tl1e fetus. The vein of the chorionic villus returns oxygenated blood and nutrients to the fetus. Fetal capillaries in tl1e chorionic villi are separated from direct contact witl1 tl1e motl1er's blood by the membranes of each villus. 111is arrangement allows contact close enough for exchange and avoids mixing of fetal and maternal blood, which may not be compatible.

    Metabolic Functions The placenta produces some nutrients needed for the embryo and for its own functions. Substa.nces synthes ized include gly· cogen, cholesterol, and fatty acids ( Moo re & Pe rsaud, 2008a, 2008b).

    Maternal Component

    Transfer Functions

    Development. When conception occurs, cells of the endometrium w1dergo changes that promote early nutrition of the embryo and enable most of the uterine lining to be shed after birth. These changes convert endometrial cells into the decidua. In addition to providing nourishment for the embryo, the decidua may protect the mother from uncontrolled invasion of fetal placental tissue into the uterine wall. The three decidual layers are: The decidua basalis, which underlies the developing embryo and forms the maternal side of the placenta.

    Exchange of m.)'gen, nutrients, and waste products across the chorionic villi occurs by several methods. Table 12-4 presents examples of substances transferred between the mother and the developing fetus. Placental trans fer of harmful substances also may occur. Most substances that enter the mother's bloodstream can enter the fetal circulation, and many agents enter it almost immediately. Gas Exchange. A key function of the placenta is respiration. Oxygen and carbon dioxide pass through the placental membrane by simple diffusion. The average oxygen partial pressure

    Conception and Prenatal Development

    (Po 2) of maternal blood in the intervillous space is 50 mm Hg. The average blood Po2 in the umbilical vein (after oxygenation) is about 30 mm Hg (HalJ, 20 11). The fetus can thrive in this low-oxygen environment for three reasons: Fetal hemoglobin can carry 20% to 50% more oxygen than adult hemoglobin. The fetus has a higher oxygen-carrying capacity because of a higher average hemoglobin (15 to 24 g/dL) and hematocrit value (about 44% to 70%). Hemoglobin can carry more oxygen at low carbon dioxide partial pressure ( Pc o 2) levels than it can at high ones ( Bohr effect). Blood entering the placenta from the fetus has a high Pc o 2, but carbon dioxide diffuses quickly to the motl1er's blood, where the Pco 2 is lower, reversing the levels of carbon dioxide in maternal and fetal blood supplies. Therefore tl1e fetal blood becomes more alkaline and the maternal blood becomes mo re acidic. This difference aUows the motl1cr's blood to give up oxygen and the fetal blood to co mbine with oxygen readil)'. Nutrie11t Tra11sfer. The growing fetus req uires a constants up ply of nutrients from the p regna n t woman. Glucose, fatty acids, electrolyte.s, and vitamin s pass read ily across the placenta. Waste Removal. In add itio n to ca rbon d iox ide, urea, uric acid, and bilirubin are read il y transferred from the fetus to the mother for disposal. Antibody Tra11sfer. The immunoglob ulin G (lgG) maternal antibodies are the primary ones transferred to the fetus by the placenta. Transfer of lgG antibodies to the fetus may provide temporary ( passive) immunity against diseases such as rubella or tetanus if the mother is immune. The preterm or small-for-gestational-age infant has little disease protection because many maternal antibodies are not transferred until late pregnancy and are poorly transferred if placental function is inadequate. Passage of antibodies from mother to fetus also may be harmful. If maternal and fetal ABO blood types or Rh factors are not compatible, the mother either may already have or may produce antibodies against fetal erythrocytes. The mod1er's antibodies may then destroy the fetal erythrocytes, causing fetal anemia or even fetal deatl1. Transfer of Matema I Hormones. Most maternal protein hormones do not reach tl1e fetus i11 amounts sufficient to cause abnormalities.

    Endocrine Functions The placenta produces many ho rmones necessary for normal pregnancy. h CG causes the co rpus luteum to persist and secrete estrogens and progeste ro ne for the fi rst 6 to 8 weeks. The placenta gradually takes over production of estrogens and progesterone, and the corpus luteum regresses after 20 weeks. When a Y chromosome is present in the male fetus, hCG also causes the fetal testes to secrete testosterone necessary for normal development of male reproductive structures. Human chorionic somatomammotropin, formerly called human placental lactogen, promotes normal nutrition and growth of the fetus and maternal breast development for lactation. The hormone decreases maternal insulin sensitivity and

    utilization of glucose, making more glucose available for fetal growth. Steroid hormones secreted by the placenta include es trogens and progesterone. Estrogens cause enlargement of the woman's uterus, enlargement of the breasts, growth of the ductal system of the breasts, and enlargement of the externa l genitalia. Estrogens enhance uterine activity, particularly as term approaches, playing a role as labor begins. Progesterone causes the endometrium to change into the decidua, providing nourishment for the early conceptus. Progesterone reduces uterine contractions and suppresses maternal reactions to fetal antigens to prevent spontaneous abortion. Progesterone acts with estrogens and other hormones to cause growd1 of tl1e breasts, budding of the alveoli that wil I secrete milk, and development of secreto ry cha racteri stics in the alveolar cells. Other hormones produced by the placenta include human chorion ic thyrotropin and human cho ri o nic ad renoco rticotropin as weU as many growth facto rs.

    Fetal Membranes and Amniotic Fluid The two fetal membranes are the amnion (inne r membrane) and the chorion (o uter membrane). The two membranes are so close as to be one, although they ca n be separated. Together they are often caUed the bag of waters. If they rupture in labor, amnion and chor ion usually rupture together, releasing the amniotic fluid within the sac. The amnion is continuous with the surface of the umbilical cord, joining the epithelium of the fetus's abdominal skin. Chorionic villi proliferate over the entire surface of the gestational sac for the first 8 weeks after conception. A conceptus observed at this tinie looks like a shaggy sphere with the embq'O suspended inside. As the embryo grows, it bulges into the uterine cavity. The villi on tl1e outer surface gradually a trophy and form the smooth-surfaced chorion. The remaining villi continue to branch and enlarge to form the fetal side of the placenta. Amniotic fluid protects the growing fetus and promotes normal prenatal development. Amniotic fluid protects the fetus by: Cushioning against an impact to the maternal abdomen Providing a stable temperature Amniotic fluid promotes normal prenatal development by:

    Allow in g symmetric development of the fetus as body surfaces fold toward die midline Keep ing the membran es from adhe ring to developin g fe tal parts Providing room ;md buoya ncy fo r fetal movement Amniotic ti uid is derived from two so urces: fetal urine and fluid transpo rted from the maternal blood across the amn ion. Cast-off fetal epithelial cells and vern ix are suspended in the amniotic fluid. The water of the amniotic fluid change.s by absorption across the amnion, returning to the mother. Some fluid is absorbed by the fetal lungs with b reath ing movements. Additional amniotic fluid is swallowed and absorbed by the fetal digestive tract. The volume of amniotic fluid increases during pregnancy, until it is about 500 to IOOO mL at term, although the volume

    CHAPTER 12 var ies in the last trim ester ( Blackburn, 2013; Beall & Ross, 2009; Carlson, 2009; Hall, 20 11 ). An abnormally small quantity of fluid (less than 50% of the amount expected for gestation, or less than 500 rnL at term) is called oligohydrnnmios and is associated with poor fetal lung development and malformations that result from compression of fetal parts. Oligohydramnios may occur because the kidneys fail to develop, urine excretion is blocked, or placental blood flow is inadequate. Hydrnmnios (also called polyhydra11111ios) is the opposite situation, in which the quantity may exceed 2000 mL. H ydramn ios may occur when the fetus has a severe malformation of the cenLral nervous system or gastrointestinal tract that prevenLS normal ingestion of amniotic fluid. Fetal Circulation. 'l11e course of fetal blood circulation is from the fetal heart, to the placenta for exchange of oxygen and waste products, and back to the fetus for delivery to fetal tissues ( Figure 12- 9, A).

    Conception and Prenatal Development

    229

    Umbilical Cord The umbilical cord has two arteries that carry blood tha t is high in carbon dioxide and other waste products away from the fetus to the placenta, where these substances are transferred to the mother's circulation for elimination. The umbilical vein carries freshly oxygenated and nutrient-rich blood from the placenta back to the fetus. Tiie umbilical arteries and vein are coiled within the cord to allow them to stretch and prevent obstruction of blood flow through them. The entire cord is cushioned by a soft substance called \V11nr1011's jelly to prevent obstruction caused by pressure.

    Fetal Circulatory Circuit Because the fetus does not breathe air or metabolize substances in the liver, several alterations of the postbirth circulatory route are needed. Three shunts-the ductus venosus, the foramen

    ovale, and the ductus arteriosus-divert most circulating blood away from the lung.s and liver. Oxygenated blood from the placenta enters the fetal body through the umbil ical vein. About half the o:-.11genated venous blood goes through the liver du rin g early pregnancy and the rest bypasses the liver mid enters the inforio rvena cava through the first shun t, the duc111.1 venosus. The blood then enters the right atrium. Most of the blood passes d irectly into the left atrium through the second shunt, the fornmen ovale, where it mixes with the small amount of blood return ing fi-om the lung.~. Blood is pumped from the left ventricle into the ao rta to nou rish the body. A small amount ofblood from the right ventricle is circulated to the lung; to nourish the lung tissue. The rest of the blood from the right ventricle joins oxygenated b lood in the aorta through the third shunt, the duaus arteriosus. The head and upper body receive the greatest amount of oxygenated blood. During late pregnancy the liver receives 75% to 80% of the oxygenated venous blood (Blackburn, 2013; Fineman & Clyman, 2009; Jones, 2009b).

    Resistance lo blood flow through the uninflated lungs is high, causing the right ventricle to work harder and have a thicker waU than the left. After breathing is establ ished, resistance to pulmonary blood now falls a nd syste mic resistance rises, causing the right ventr icular wall to become th inner wh ile the left becomes thicker.

    Changes in Blood Circulation After Birth Fetal circulatory shw1ts are not needed after birth because the infant oxygenates blood in the lungs, metabol izes substances in the liver, and stops circulating blood to the placenta (see Figure 12-9, B). As the infant breathes, blood flow to the lungs increases, pressure in the right heart falls, and the foramen ovale closes. Pressure in the aorta rises as pressure in the pulmonary artery falls, causing the direction of blood now through the ductus arteriosus to reverse, from the aorta into the pulmonary artery. The duct us arteriosus constricts as t11e arterial oxrgen level rises. The duct us venosusconstrictswhen blood now from the umbilical cord stops.

    3. Serum tests for syphilis. Other routine admis sion tests may Include serum HIV. vaginal gonorrhea and chlamydia. or vaginal group B streptococcus {GBS) tests. Routine drug screens are common for a woman who has not had prenatal care

    1. Hemoglobin at least 10.5 g/dL: hematocrit at least 33%. 2. The woman who is Rh·negative and has had regular prenatal care receives Ah im· mune globulin at 28 weeks of gestation to prevent formation of anti-Rh antibodies. 3. Negative on all. GBS screening may have been done recently during a prenatal visit late in pregnancy \see Chapter 13. Table 13· 1. p. 238 for more information).

    1. Values lower than these reduce maternal resel\ie for normal blood loss at birth. 2. Ah-negative mothers need Rh immune globulin after birth if the infant is Ah-positive.

    3. A positive test indicates that the baby could be infected and needs treatment after birth. The mother should be treated if she has not been treated already. Maternal antibiotics are grven for positive GBS to reduce newborn infection from organisms within the vagina.

Eiqilarn the procediie to the woman. 1he reasons and what is !curd at each step to teach her and reassiie her when the assessment fincings are normal. 2. Ask the woman to empty her blac;ler ii she has not dooe so recently to reduce discomfort during palpation and make fetal parts easier to feel. Have her lie oo her back with her knees flexed sli~tly or head slightly elevated to help her relax her abdominal muscles. Place a small pillow or folded towel under one hip 10 prevent supine hypotension. 3. Wash your hands with warm water to prevent transmission of microorganisms and to make your hands warmer when touching the woman. Wear gloves to avoid contact with the woman's secretions as indicated. 4. Stand beside the woman. facing her head, with your dominant hand nearest her, because the first three manewers are most easily performed in this position. First Maneuver 5. Palpate the uterine fund us to distinguish between a cephalic and breech presentation. The breechlbuuocks) is softer and more irregular in shape than the head. Moving the breech also moves the fetal trunk. The head is harder. with a round, uniform shape. The head can move without the entire fetal trunk moving.

    Third Maneuver 7. Palpate the suprapubic area to confirm the presentation felt in the first ma newer and to determine if the presenting part is engaged. If a breech was palpated in the fundus. expect a hard. rounded head in 1his area. Grasp the presenting part gently between !he 1humb and fingers. If the presenting part is not engaged, grasping wi1h 1he fingers moves it upward in the uterus.

    8. Omit the fourth maneuver if the fetus is in a breech presentation. because this manewer is done only in cephalic presentations 10 deter· mine if the fetal head is flexed.

    Second Maneuver 6. Hold your left hand steady on one side of the uterus while palpating the opposite side of lhe uterus wilh your right hand to detennine which side the fetal back is on and which side lheanns and legs rs mall parts") areon. Then hold your right hand steady while palpating the opposite side of the uterus wilh your left hand. The fetal back is a smooth, convex surface. The fetal arms and legs feel nodular, and the felUs often moves them during palpation.

Assess the fetal prese nta tion and position and the FHR. Note the colo r of the am niotic fl uid and the time of rupture if th e membranes have ruptured. Labor Status. Determine the woman's labo r status by: Assessing her contraction pattern Determining cervical dilation and effacement; and fetal station (measurement of fetal descen r in the pelvis related to the ischial spines), presentation, and position Determining if her membranes have ruptured Ph}~ical Ei...amination. If birth is not imminent, perform a brief physical examination to evaluate the woman's overall health. Important general observations that relate to birth

    include the presence and location of edema, abdom inal scars, and the heigh t of the fund us.

    Admission Procedures Notifying the Physician or Midwife. After assessment, con-

    tact the woman's birth attendant to report on her status and obtain orders. Include the following data in the report: Gravidity, parity, abortions (spontaneous and elective). and tenn and preterm births EDD; fundal height Contraction pattern Fetal presentation and position Cervical dilation and effacement; feral presentation and position; station of the presenting part FHR and pattern Maternal vital signs Any identified abnormalities or concerns about the maternal or fetal condition Pain, anxiety, or other reactions to labor lf the woman is admitted, any of several procedu res may be done. Consent Forms. The woman signs co nsent fo r ca re du ring labo r, anesthesia, vagi nal bir th, cesa rean bir th, and blood transfusion. A separate co nsent fo r huma n immunodeficiency virus (HJV) is frequen t. Consent for newborn ca re is often completed as well. A separate consent for tubal li gation must be signed for women desiring permanent sterilization at delivery.

    l

    344 Laboratory Tests. A woman has routine admission labora tory tests plus other tests ifind icated by her history and physical examination. Simple tests may be done nn the unit, such as: Hematocrit Blood glucose levels Midstream urine specimen for dipstick evaluation of protein , glucose, and ketone levels. Urinalysis and culture and sensitivity may be ordered for possible urinary tract infection. Other common routine tests done for every admitted perinatal patient include: Complete blood count Blood type and Rh factor Rapid plasma reagin ( RPR) or ocher test for syphilis Hepatitis B surface antigen HIV testing, if the woman consents Intravenous Access. If used, intravenous access is usuaUy started with at least an 18-gauge catheter. A saline lock may be used, or the woman may receive continuous infusion of fluids. The lock facilitates walking during ea rly labor and is les.s associated with illness, but it provides quick access if fluids o r drugs are needed. Continuous flu id in fusion helps prevent or rel ieve dehydration and is needed if ep idural block analgesia is used Isotonic elel1rolyte solutions, such as lactated Ringer's solution, are common.

    Assessments After Admission After the admission assessment, the woman and her fetus need regular assessments based on their risk status and on whether interventions such as epidural analgesia are needed. General guidelines for continuing assessments are listed here. The woman is usuaUy observed ifit is unclear after the initial assessment whether she is in true labor. After I or 2 hours, progressive cervical changes (effacement, dilation, or both) suggest true labor. Assess tlie woman and fetus during the observation period as if she were in early labor. Fetal Assessments. Fetal asses.sments continue to identil)• signs of weU- being and signs that suggest compromise. The principaJ fetal assessments include the FH R and patterns and tlie character of the amniotic fluid. Abnormalities revealed in these assessments may be associated with impaired fetal gas exchange or infection. FIIR. The Fl IR is usually assessed using electronic fetal monitoring. However, interm ittent auscultat ion may be done with a Doppler transducer or a fetoscope (see Chap ter 17). Amniotic Fluid. The membranes may rupture spontaneously (spontaneous rupture of membranes [SROMJ ). or amniotomy (a rtificial rupture of memb ranes [AROMJ) may be done. Assess the FHR for a l least I minute after the membranes rupture. The umbilical cord cou ld be displaced in a large fluid gush, resulting in compression and interruption of blood flow through it. Charting related to membrane rupture includes the time, FHR (which will appear on an electronic fetal monitor strip), and character oftl1e fluid. Amniotic fluid should be clear and may include bitsofvemix, the creamy fetal skin lubricant. Cloudy, yellow, or foul -smeUing amniotic fluid suggests infection. Green fluid indicates that the fetus has passed meconium before birth. Meconi um passage may have been a response Lo transient hypoxia, although the cause

    may remain unknown. Meco11ium-sta ined fluid is not usuaUy noted in the preterm infant, although it may be seen in the late preterm newborn born at 34 °;, to 36 o/7 weeks of gestation. Describe quantity in approximate terms. At term, a "large" amount is more than 1000 ml; a "moderate" amount is about 500to1000 ml; and "scant" amniotic fluid is only a trickJe, barely enough to detect. If the fetus is weU down into the pelvis when the membranes rupture, a smaU amount of fluid in front of the fetal head may be discl1arged (forewaters), with the rest lost at birth. Maternal Assessments. Several maternal assessments, such as vital signs and contractions, also relate to the heaJth of the fetus. Vital Signs. Guidelines for maternal vital signs assessment are listed in Table 16- 2. Hypotension, hypertension, elevated pulse and respiratory rates, and elevated temperature should be reported, and repeat assessments should be done more frequently. Contractions. Contractio ns ca n be assessed by palpation (see Procedure on p. 345) or with the elect ronic fetal monitor, using the guidel in es in Table 17- 1. Witl1 external monitoring, a combination of techniques is o rten used. Progress of Labor. Period ic vaginal exam inations determine cervicaJ dilation and e ffacement and fetal descent. The frequency of vaginal examinatio ns depends o n the woman's parity, the status of her membranes, and the overall speed of her labor. Vaginal examinations are limited to avo id introducing microorganisms from the perinea! area into the uterus. Intake and Output. Oral and intravenous intakes are recorded. Each voiding is recorded. Labor or regional anesthesia reduces a woman's urge to void, so check her suprapubic area every 2 hours to identify bladder distention. Check more frequently if she has received large amounts of intravenous fluid. Pressure of the fetaJ head on tJie rectum in late labor makes many women feel the need to defecate, even if they had epidural analgesia. Look at tl1e woman's peri11eum for crowning of the fetal head if she abruptly expresses a need to defecate or says "something feels different down Lhere" or a similar remark. Respon!>e to Labor. 111e woman's behavioraJ responses change as labor intensifies. She withdraws from interactions but needs more nursing presence and reassurance. She may become more anxious because of pain and fear of bodily injur)'. unknown outcome, loss of control, unresolved psychological issues that influence her readiness to give birth (e.g., sexual abuse, previous b irtl1 experiences), or unexpected occu rrences during labor. Women vary in the way they ha n die the pa in oflabor. The nurse must constantly assess whether added pain co ntrol measures are needed, because laboring women are often uncertain about when they are ready for added rel ief measures. Behaviors that suggest the woman needs help witl1 p;1in management include: Expressing tliat nonpharrnacologic measures are ineffective. Tensing her muscles or arch ing her back during contractions. Persistence of muscle tension ber.11een contractions. A tense facial expression; rolling in the bed. Expressions such as "I can't take it anymore." Specific requests for medication or other pain control sucl1 as epidural (see Chapter 18).

    PROCEDURE

    Paloatinq Contractions Purpose To determine whether a contraction pattern is typical of true labor. To identify abnormal contractions that may 1eopardize the health of the mother or fetus or irdicate another complica!lon. 1 • Assess contractions with each assessment ol the fetal heart rate. Assess several contractions to evaluate aveiage chaiactei1st1cs of the pauem Palpate contractions periodically if an external fetal mon1toris used because the monitor is less accurate for 1ntens1ty as a result of vaiiations in the thicl:ness of the abdominal fat pad. mateinal pos1!IOI\ and fetal position. 2. Place the fingertips of one hand on the area where the contractions aie best felt. usually the uterine flJldus. The mother usually feels sensations in her lower abdomen and back. Use liijlt pressure. and keep,,our fingertips relatively sti ll rathe1than moving them over the uterus. because movi ng your hard o\.er the uterus may stimulate contraetions ard gi\.e an inaccurate view of their true pattern. The fingertips are more sensitive to !he first tightening of the uterus. 3. Note the timewhen each contraction begi1is and ends: a. Determine the frequency by noting the average time that elapses from the beginning of onecontraction 10 the beginning of the next one. b. Determine theduration of contractions by noting the average time in seconds from beginning to end or eachcontraction. c. Determine the i nteival between contractions by noting the average time between the end or onecontraction and the beginning or the next one.

    The Support Person's Response. Labor is stressful for the woman's suppo rt perso n, often the baby's father. He may become anxious, fearful , or tired. He feels a responsibility to protect and suppo rt the wo ma n but may have limited resources for doing so. It is difficult for him to watch the woma n he loves in pain, even if the pain is no rmal an d she declines medica tio n. He may respond to stress in many ways: by becoming q uiet, suffering silently, pacing, expressing an ger, o r even vomiting. Some fathers respond by leaving the room frequently o r for long periods, whereas others resist taking even short breaks that they need. Nurses encou rage and va lue the father's presence during labor and birth. This attitu de, h owever, may conflict with a couple's cultural norms, whi ch may di ctate that birth is a strictly femal e activi ty. The fa ther may be puUed in two directions, wanting to be included but· hesitant because men in his culture are not customaril)' involved in birth. The nurse should respect the valu es of each couple and their wishes about the father's involvem ent ( Da rby, 2007). The support p erson also may be a parent o r other relative, a fr iend of either sex, or a homosexual partne r. The nmse must remember that tmyo ne who assists the woman during labo r may feel anxious or helpl ess al ti mes. Reassu rance and care for the labor partner stre ngthe n that person's abil ity to support the woman and in crease the likelihood that both will view the b irth experience as positive.

    4. Estimate the average intensity of contractions 11( noting how easily the uterus can be indented during the peak of the contraction. a. Mild contractions are easily indented wth the fingertips. They feel similar to the tip of the nose. b. Moderate contractions can be 1rdented with more difficulty. They feel similar to the chm. c. Firm contractions feel ·woody" and ca mot be readily indented. They feel similai to the forehead. 5. Report hypertonic contractions that can reduce placental blood flow: a. Oocurring less thai1 2 mu111tes apart ard no more than 5contractions in 1o minutes b. Durations longer than90to 120secords c. Inteivals shorter than ll secords d. Incomplete relaxation of the uterus between contractions Hypertonic contractions reduce placental blood flow by prolonged compression of vessels that supply the imeivillous spaces. See Chapter 17 !or details and inteiventions.

    labor may be discharged to await ac tive labor, es peciaUy if she is a nullipara and lives nearby.

    I Nursing Diagnosis and Planning The woman may be frustrated because she canno t teU whether labor is real. She may resist returning to the b irth center, possibly delayi ng care needlessly. A nursing diagnosis that a pplies to many wome n with false labor contractio ns is: · Deficient Knowledge: C haracteri stics o f true labo r Expected Outcomes. After tl1e nu rse teaches the woman and her support, tl1ey will restate tlie signs o r s ymptoms for which she should re turn to the birth center.

    I

    I Interventions I Providing Reassurance A woman sent home after observation often feels foolish and frustrated. Reassure her that even professionals cannot always identify true labor and that false labor and early true labor have similar characteristics. Tell her that important preparat ion occurs du ring late pregnancy, such as cervical soften ing and fetal descent, even if objective progress like cerv ical d ilation has not yet occu rred. Teaching. Review guidelin es for return ing to the bir th center with her: regular contrac tions, leaking of amn iotic fluid, active bleeding (more than bloody show and often not mixed with mucus), and decreased fetal movement. Explain that these are only guidelines and that she sh ould call or re turn if she has any concerns. It is better for her to re turn with another false alarm than to arrive at the birth center in advanced labor or to develop complications at ho me.

    After assessment it may be a ppa rent that the wo man is not in true labor. If findings are no rmal and he r me mbranes are intact, sh e is usua Uy discharged ho me. The wo man who is in very early

    I Evaluation Can the woma n a nd her support person describe guidelines for returning to tl1e birtl1 center?

    NURSINli CARE

    The Woman with False or Early Labor I Assessment

    346 I NURSING CARE , The Woman in True Labor The admission assessmen l may confirm that the woman is in true labor, or true labor may be evident after observation. Nursing diagnoses and related care change during labor because the intrapartum period is an evolving process that involves two people who are connected: a mother and her fetus. Nursing care and medical or nurse-midwife care are also linked throughout. Care of mod1er and fetus before birth relates ro fetal oxygenation, maternal discomfort, and maternal injury. Nursing diagnoses are often interrelated during labor. For example, anxiety or fear ca n affect pain-relief measures. A maternal fluid volume deficit can alter feta.I oxygenation because less blood is available to circulate to the placenta.

    D SAFETY ALERT Conditions Associated w ith Fetal Com rom ise ~

    • • • • • • •

    A fetal heart rate (FHA) outside the normal range of 110 to 160 beats per minute (bpmt for a term fetus. Meconium-stai11ed (greenish) thick amniotic ftuid. Cloudy. yellowish. or foul odor to the amniotic ftuid (suggests infection). Excessive frequency or duration of contraeti ons. Incomplete uterine relaxation. Maternal hypotension lmay divert blood ftow ~vay from the placenta to ensure adequate perfusion of the maternal bra~n and heart). Maternal hypertension (may be associated with vasospasm in spiral arter· ies. which supply the intervillous spaces of the placenta). Matemal fever (38° C(100 4° FJ or higher!.

    Note: Chapter 17 provides detailed fetal assessments and interpretation of data.

    I FETAL OXYGEN_A _T_IO_N_ _ _ _ __ _ I Assessment Refer to assessments listed in Table 16-2 for intrapartum assessments. The main assessments related to feral well -being are:

    FHR Contractions: frequency, duration, intensity, resting tone, interval Character of amniotic fluid, amount, and time ofruptu re Maternal vital signs Chapter 17 contains deta iled in formation about FHR and related observations. I Nursing Diagnosis and Planning Most fetuses tolerate labor well, but maternal conditions such as hypotension or hypertension, fever, excessive (tetanic) contractions, or fetal conditions that co mpress the umbilical cord can compromise fetal oxygenation. Nursing measures may be able to restore good fetal oxyge nation or it may be necessary to noLify the birth attendant for collaborative patient care. The nursing diagnosis for fetal observation throughout labor would be: Risk for Ineffective Peripheral Tissue Perfusion: Fetal, related to interruption in oxygen-rich blood flow through the placenta or through the umbilical cord.

    Expected Outcome. The FHR and co ntraction patterns are

    expected to remain reassuring throughout labor. I Interventions I Promoting Place11tal Fune ~ rn Maternal positioning is the most common measure to promote placental function during normal labor. The woman can choose any position other than supine to avoid aortocaval compression that would reduce blood flow to the placenta. If she must be in the supine position for a procedure such as carheterization, a small pillow or rolled towel or blanket wedged under one hip shifts her uterus to one side to maintain good placental blood flow. I Observing for ConditJons Associated with Fetal Compromise Determine whether an)' conditions associated with fetal compromise exist. If any are identified, assess the fetus more frequently and notify the birth attendant.

    I Evaluation A reassuring constant fetal evaluation in cludes a reassuring FHR pattern and ongo ing maternal assessments widlin expected limits. Throughout labor, the nurse co mpares actual data widl the norms for the mod1er and fetus. See Chapter 17 fo r integration of fetal assessments into intrapartum care planning.

    I DISCOMFORT I Assessment See Table 16-2 for continuing assessments of the laboring woman. I Nursing Diagnosis and Planning Labor is painful. Women vary in their responses to pain and in the pain management methods they choose. Providing choices for pain management and supporting the woman's choice increase her sense of control over her birth experience. The woman who successfully masters the pain and other physical demands of labor is more like!)' to view her experience as positive. Her support person is likely to feel more satisfaction with the experience as well. Pain and Anxiety are related nursing d iagnoses. Excess anxiety intensifies pain perception, and acute pain wo rse ns anxiety. The nurse clusters assessment data a nd co nsiders bodl pain and anxiety when determining the best app roacl1 to pain relief. Several cues may suggest that anxiety is a major contr ibuto r to labor pain that the woman might otherwise easily manage: a previous poor experience during birth or expressions of worry and concern. The nursing diagnosis is therefore: · Pain related to effects of uterine co ntrac tions. Expected Outcomes. The woman will state that she is able to tolerate labor pain satisfactorily and will use breathing and relaxation techniques during labor. The woman's partner will ex']>ress satisfaction with his or her ability to support her by discharge.

    _

    CHAPTER 16 Giv ing Birth _.__ I Interventions I Providing Comfott Measure Ordinary measures reduce irritating surroundings that impair a woman's ability to relax and use coping skills. Nurses must be creative when providing comfort to the laboring woman. Lighting. Soft, indirect lighting is soothing, whereas a bright overhead light is an irritant. Bright lights imply a hospital ("sick") atmosphere rather than the normal life event that birth is. Use the overhead light only when needed. A small flashlight is handy if the woman wants her room truly dark. Temperatura. Labor is work. Women in labor are often hot and perspiring. Cool, damp washcloths on the woman's face and neck promote comfort. Keep an ample supply of damp washcloths available, and change them often to keep d1em cool. An electric fan circulates air in the labor room and directs a breeze on the woman. lie sure that the fan does not blow on the infant after bird1, because cool air might cause hypothermia. Have the woman wear socks if her feet are cold. She may shake, sometimes intensely, although her temperatu re is normal and she den ies be ing cold. Cleanliness. Bloody show and am ni otic fluid leak from the woman's vagina during labor. Change the sheets and gown as needed to keep herd ry and co mfortable. Let he r preferences be the guide, because she may not want to be disturbed during late labor. Change the underpad regularly to reduce microorganisms that may ascend into the vagina. A folded towel absorbs larger quantities of amniotic fluid than the pad alone. If using pillows near where fluid will leak, protect them with underpads. Mouth Care. Ice chips, Popsicles, or hard candy on a stick reduces the discomfort ofa dry mouth. Avoid excess sugar intake that might contribute to neonatal hypoglycemia after birth. Oral intake restrictions among low-risk laboring women are a conflict among professional organizations in the United States and Canada. 111e American College of Nurse-Midwives advocates d1at d1e low- risk woman self-determine her oral intake. The World Health Organization does not promote interference with oral intake during labor ($harts-Hopko, 2010). If oral intake is contraindicated, brushing the teeth or sinlply rinsing the mouth helps. Many women appreciate a moist washcloth applied to their lips. Bladder. A full bladder intensifies pain during labor and can delay fetal descent. Remind the woman to empty her bladder at least every 2 hours. Ca thete rization is often needed. Positioning. Upright posit ions add the fo rce of gravity to fetal descen t. Wom en who labo r up right often need less an al gesia and have more effective contractions. Their in fants often have improved pH
