Study guide
Health Promotion and Maintenance covers the nurse's role in preventing illness and supporting normal development across the entire lifespan, from a newborn's first assessment to health screening in an older adult. This chapter is educational only; specific immunization schedules, screening intervals, and contraceptive guidance change periodically and should always be checked against current CDC and professional-society recommendations. Expect teaching-focused questions that test whether you can recognize normal versus concerning findings and communicate them in plain language.
Growth and Development Across the Lifespan
Developmental milestones give the nurse a baseline for what is expected at a given age, so deviations can be caught early. In infancy, gross motor milestones progress roughly from head control by two to four months, to rolling by four to six months, sitting unsupported around six months, and walking near twelve months, though a reasonable range exists around each and single missed milestones are evaluated in context rather than treated as a diagnosis. Erik Erikson's psychosocial stages are commonly referenced in nursing education: infancy centers on trust versus mistrust, toddlerhood on autonomy versus shame and doubt, preschool on initiative versus guilt, school age on industry versus inferiority, adolescence on identity versus role confusion, young adulthood on intimacy versus isolation, middle adulthood on generativity versus stagnation, and older adulthood on ego integrity versus despair. Applying this, a toddler who insists on doing tasks independently, such as feeding herself messily rather than accepting help, is displaying developmentally appropriate autonomy, and a caregiver who takes over the task every time may be unintentionally undermining that development. In older adults, expected changes include some decline in visual acuity, hearing, and reaction time, alongside preserved crystallized intelligence and vocabulary; the nurse's role is to distinguish normal aging from a pathologic process, such as sudden confusion, which is not a normal aging change and warrants prompt evaluation.
Antepartum, Intrapartum, Postpartum, and Newborn Care
Antepartum care focuses on monitoring maternal and fetal well-being across pregnancy: tracking weight gain, blood pressure trends (watching for preeclampsia, marked by new hypertension with proteinuria or other organ involvement after twenty weeks), fundal height as a rough gauge of gestational age, and fetal movement. Common patient teaching includes avoiding alcohol and unpasteurized foods, taking a prenatal vitamin with folic acid to reduce neural tube defect risk, and reporting warning signs such as vaginal bleeding, severe headache, or decreased fetal movement immediately. Intrapartum care centers on monitoring labor progress (cervical dilation and effacement, contraction pattern) and fetal heart rate patterns; a reassuring fetal heart tracing typically shows a baseline in the normal range with moderate variability, while recurrent late decelerations or minimal variability are concerning findings requiring prompt evaluation. Postpartum care includes assessing uterine involution (the uterus should feel firm and progressively descend below the umbilicus), lochia progression from bright red to lighter discharge over days to weeks, and screening for postpartum mood changes, distinguishing transient 'baby blues' from postpartum depression, which involves persistent symptoms and requires referral. Newborn care includes the Apgar score assessed at one and five minutes after birth (rating heart rate, respiratory effort, muscle tone, reflex irritability, and color), maintaining thermoregulation since newborns lose heat quickly, and teaching new parents safe sleep practices, such as placing the infant on their back on a firm surface with no loose bedding, to reduce sudden infant death syndrome risk.
Health Screenings and Immunizations
Targeted screenings are recommended at different life stages and the nurse's role often includes performing basic screens and referring abnormal findings. Vision screening in young children helps catch amblyopia early, when treatment is most effective; a caregiver-reported concern, such as a child holding books very close to the face, warrants referral rather than reassurance alone. Nutritional screening across the lifespan looks for both undernutrition (unintended weight loss, low intake) and overnutrition, and validated depression screening tools, such as brief structured questionnaires, are used across settings, from postpartum visits to older-adult wellness checks, because depression is common and underrecognized in both populations. Immunization schedules are published and updated by the CDC's Advisory Committee on Immunization Practices and change periodically, so a candidate should understand the general categories, such as childhood series against diseases like measles, mumps, rubella, and pertussis, and adult recommendations like periodic tetanus boosters and age-based vaccines, without memorizing exact current-year intervals as fixed forever. When a caregiver expresses vaccine hesitancy, therapeutic communication (open-ended questions, acknowledging the concern, providing evidence-based information without judgment) is more effective than dismissing the concern outright. High-risk behavior counseling, such as discussing safer sex practices, substance use, or seatbelt and helmet use with adolescents, uses similarly nonjudgmental, direct communication, since adolescents are more likely to disclose honestly when they do not feel lectured.
Family Planning, Home Safety, and Self-Care Teaching
Family planning education covers a range of contraceptive methods with different mechanisms, effectiveness, and side-effect profiles: barrier methods (condoms, which also reduce sexually transmitted infection risk), hormonal methods (combined oral contraceptives, patches, rings, injections), long-acting reversible methods (intrauterine devices, subdermal implants), and permanent methods (tubal ligation, vasectomy). The nurse's teaching role is to present accurate, unbiased information about effectiveness and risks so the client can make an informed choice consistent with their own values, rather than steering toward a particular method. Home safety teaching is tailored to developmental stage: for a household with a new crawling infant, teaching includes covering electrical outlets, securing furniture that could tip, and keeping small objects and cleaning products out of reach; for an older adult with mobility changes, teaching includes removing throw rugs, improving lighting, installing grab bars, and reviewing medications that increase fall risk, such as sedatives. Self-care teaching for chronic conditions, such as showing a newly diagnosed client with diabetes how to check blood glucose and recognize signs of hypoglycemia, is most effective when it uses teach-back, meaning the nurse asks the client to explain or demonstrate the skill in their own words rather than simply asking 'do you understand?' NGN-style scenario: A nurse is teaching a first-time mother, Ms. Okafor, before newborn discharge. The infant is exclusively breastfeeding, and Ms. Okafor asks whether it is fine to place the baby on his stomach at night because he seems to sleep better that way. The nurse recognizes this as an unsafe sleep practice and explains that placing the infant on his back reduces the risk of sudden infant death syndrome, then confirms understanding by having Ms. Okafor describe how she will position the baby at home.
Key terms
- Developmental milestone
- — An expected physical, cognitive, or social skill achieved within a typical age range, used to screen for delays.
- Erikson's psychosocial stages
- — A theory describing a conflict or task characteristic of each life stage, such as trust versus mistrust in infancy.
- Preeclampsia
- — A pregnancy complication after twenty weeks marked by new-onset hypertension with proteinuria or other organ involvement.
- Fetal heart rate variability
- — Fluctuation in the fetal heart rate baseline used to assess fetal oxygenation status during labor; moderate variability is reassuring.
- Uterine involution
- — The postpartum process by which the uterus returns to its pre-pregnancy size and position.
- Apgar score
- — A newborn assessment scored at one and five minutes after birth across heart rate, respiratory effort, muscle tone, reflexes, and color.
- Postpartum depression
- — A persistent mood disorder following childbirth, distinct from transient baby blues, requiring screening and referral.
- Teach-back
- — A teaching-verification method where the client repeats or demonstrates information in their own words to confirm understanding.
- Long-acting reversible contraception (LARC)
- — Highly effective, reversible birth control methods such as intrauterine devices and subdermal implants that do not require daily action.
- Amblyopia
- — Reduced vision in one eye due to abnormal visual development in childhood, most treatable when caught early.
Exam tips
- When a question describes a caregiver worry alongside a developmental milestone, first decide whether the finding falls within a normal age range before assuming pathology.
- In maternal-newborn questions, a change from the expected trend (rising fundal height that suddenly stalls, a heart rate pattern that loses variability) is more significant than a single isolated number.
- Do not memorize an exact current-year vaccine schedule as a fixed fact; know the categories and let the exam's context clues guide age-based reasoning.
- Family planning and contraception questions test unbiased education, not steering a client toward a particular method.
- For teaching questions, the best answer usually involves teach-back or a return demonstration rather than simply asking if the client has questions.
