NCLEX Postpartum and Newborn Care — 10 Practice Questions With Rationale

Erik Erikson's eight stages of psychosocial development describe normal developmental tasks across the lifespan. Stage 5 (12-18 years): Identity vs. Role Confusion — adolescents develop a sense of self and personal identity. Success leads to fidelity; failure to role confusion and weak sense of self. The eight stages: (1) Trust vs. Mistrust (infant, 0-18 months) — develop trust through reliable caregiving; (2) Autonomy vs. Shame/Doubt (toddler, 18 months-3 years) — develop independence in toilet training, walking, choice-making; (3) Initiative vs. Guilt (preschool, 3-5 years) — assert control through play and social interaction; (4) Industry vs. Inferiority (school age, 6-11 years) — develop competence through school and activities; (5) Identity vs. Role Confusion (adolescent); (6) Intimacy vs. Isolation (young adult, 18-40 years) — develop close relationships; (7) Generativity vs. Stagnation (middle adult, 40-65 years) — contribute to society and next generation; (8) Integrity vs. Despair (older adult, 65+) — reflect on life with sense of fulfillment. NCLEX commonly tests these stages because age-appropriate teaching and care depends on understanding developmental tasks.

Separation anxiety is a normal developmental milestone reflecting cognitive development. Around 6-8 months, infants develop 'object permanence' — understanding that objects (and people) continue to exist when out of sight. This enables them to miss caregivers, leading to anxiety when separated. Separation anxiety typically peaks at 10-18 months, then gradually decreases as children develop trust that caregivers return. Stranger anxiety also emerges around 6-8 months. Nursing implications: (1) Hospitalization is particularly distressing for infants 6 months to 3 years — separation from parents, unfamiliar environment; (2) Encourage parents to stay with hospitalized infants and toddlers when possible; (3) Maintain comfort items (favorite blanket, stuffed animal); (4) Routines and consistent caregivers help; (5) Goodbye rituals and reassurance about return; (6) Brief separations (parent stepping out) help develop trust that caregivers return. Excessive separation anxiety beyond developmental norms or in older children may indicate separation anxiety disorder. Other infant developmental milestones: smiles socially (2 months), holds head up (3 months), rolls over (4 months), sits without support (6 months), crawls (8-10 months), pulls to stand (9-12 months), first steps (around 12 months), first words (around 12 months).

Recommended pregnancy weight gain depends on pre-pregnancy BMI (Institute of Medicine guidelines): (1) Underweight (BMI <18.5): 28-40 pounds; (2) Normal weight (BMI 18.5-24.9): 25-35 pounds; (3) Overweight (BMI 25-29.9): 15-25 pounds; (4) Obese (BMI ≥30): 11-20 pounds. Twin pregnancies: higher recommendations (37-54 pounds for normal BMI). Weight gain distribution: ~1-5 pounds in first trimester; ~1 pound per week in second and third trimesters. Weight gain components: baby (~7-8 lbs), placenta (~1-2 lbs), amniotic fluid (~2 lbs), uterus (~2 lbs), breast tissue (~1-3 lbs), blood volume (~3-4 lbs), fat stores (~5-9 lbs), increased fluid (~2-3 lbs). Excessive gain risks: gestational diabetes, preeclampsia, macrosomia, cesarean delivery, postpartum weight retention. Inadequate gain risks: preterm birth, low birth weight, failure to thrive. Nutrition counseling: ~340 additional calories/day in second trimester, ~450 in third; balanced diet emphasizing protein, calcium, iron, folate; prenatal vitamins; avoiding alcohol, smoking, recreational drugs, certain fish (high mercury), unpasteurized products. Track weight at each prenatal visit; address concerning patterns promptly.

APGAR (developed by Virginia Apgar in 1952) is the standard newborn assessment at 1 and 5 minutes after birth. Five categories scored 0-2 each: A — Appearance (color): 0 = blue/pale all over, 1 = pink body with blue extremities (acrocyanosis), 2 = pink all over; P — Pulse (heart rate): 0 = absent, 1 = <100 bpm, 2 = ≥100 bpm; G — Grimace (reflex irritability to stimulation): 0 = no response, 1 = grimace/weak cry, 2 = vigorous cry; A — Activity (muscle tone): 0 = limp, 1 = some flexion, 2 = active movement; R — Respirations: 0 = absent, 1 = slow/irregular, 2 = good crying. Total: 0-10. Interpretation: 7-10 normal; 4-6 moderate distress, may need stimulation/oxygen; 0-3 severe distress, immediate resuscitation. The 5-minute score is generally more predictive of outcomes than the 1-minute. Low APGAR at 5 minutes warrants additional 10-minute (and beyond) reassessments. Note: APGAR scores alone do not diagnose birth asphyxia or predict long-term outcomes; they guide immediate care. Most newborns have acrocyanosis (blue hands/feet) in the first hours, normal and not concerning.

AAP recommendation: exclusive breastfeeding for the first 6 months, then continued breastfeeding with appropriate complementary foods through at least 12 months and longer as mutually desired. WHO recommends continued breastfeeding through 2 years. If breastfeeding is not chosen or possible, iron-fortified infant formula is the alternative. Why exclusive breastfeeding for 6 months: (1) Breast milk provides complete nutrition for that period; (2) Antibodies and immune factors reduce infections; (3) GI tract is developmentally ready for milk but not solids; (4) Reduces allergy and asthma risk; (5) Reduces SIDS risk. NOT recommended before 12 months: cow's milk (insufficient iron, may cause GI bleeding in infants); honey (botulism risk); foods that are choking hazards (whole grapes, nuts, popcorn, hot dogs, raw vegetables). Solid foods are introduced around 6 months when infant shows readiness signs: sits with support, head control, doubled birth weight, shows interest in food, loses tongue-thrust reflex. Iron-rich foods first (iron-fortified cereal, pureed meat) because iron stores deplete around 6 months. Introduce one food at a time, waiting 3-5 days between new foods to identify allergies. By 12 months: solid food primary nutrition, transition to whole milk (after 12 months only).

MMR (measles, mumps, rubella) is a combination live attenuated vaccine. CDC recommended schedule: First dose at 12-15 months; Second dose at 4-6 years. Two doses provide approximately 97% effectiveness for measles, 88% for mumps, 97% for rubella. MMRV (also contains varicella) is available as an alternative. The first dose is given after age 12 months because maternal antibodies in the infant blood interfere with vaccine response until then. MMR is contraindicated in: pregnant women (live vaccine, theoretical risk to fetus — though no actual harm documented); severely immunocompromised individuals; anaphylactic reaction to gelatin or neomycin. Common side effects: fever, mild rash, swelling at injection site, joint pain (more common in adults). Serious adverse events are rare. There is NO link between MMR and autism — extensive research has refuted the discredited 1998 Wakefield study; multiple large studies confirm safety. Measles outbreaks have resurged due to vaccine refusal; nurses play key roles in family education about safety and benefits. Adults born after 1957 without evidence of immunity should receive MMR. Healthcare workers need documented immunity to MMR.

Standard adult vaccination recommendations (CDC ACIP): (1) Influenza — annually for all adults, especially essential for healthcare workers, elderly, pregnant women, immunocompromised; (2) Tdap (tetanus, diphtheria, pertussis) — at least once for all adults; then Td or Tdap booster every 10 years; Tdap during each pregnancy (27-36 weeks) for pertussis protection of newborn; (3) Pneumococcal — PCV15 or PCV20 followed by PPSV23 for adults 65+ and younger adults with risk factors (diabetes, COPD, heart disease, immunocompromised); (4) Shingles (Zoster) — Shingrix (recombinant zoster vaccine, 2 doses) for adults 50+; replaces the older Zostavax; (5) HPV — for unvaccinated adults through age 26 (and 27-45 in some circumstances per shared decision-making); (6) COVID-19 — current CDC recommendations; (7) Hepatitis A and B — for adults at risk or seeking protection; HepB now recommended for all adults 19-59; (8) MMR — adults born after 1957 without immunity; (9) Varicella — adults without immunity; (10) Meningococcal — for specific risk groups; (11) Travel vaccines — yellow fever, typhoid, etc. for international travel. Nurses commonly assess vaccination status and provide vaccinations in primary care, occupational health, and public health settings.

Comprehensive lifestyle teaching addresses major modifiable risk factors for chronic disease. (1) Nutrition: balanced diet emphasizing fruits, vegetables, whole grains, lean protein, healthy fats; limit added sugars, refined carbs, sodium, saturated/trans fats; Mediterranean or DASH diets show strong evidence; portion control. (2) Physical activity: WHO/CDC recommend at least 150 minutes moderate-intensity OR 75 minutes vigorous-intensity aerobic activity per week, PLUS muscle-strengthening 2+ days/week. Any activity beats sedentary; sitting >8 hours daily is a risk factor. (3) Tobacco: avoid all forms (cigarettes, vaping, smokeless tobacco, secondhand smoke); cessation counseling and pharmacotherapy when ready; tobacco causes major morbidity and mortality. (4) Alcohol: limit to ≤1 drink/day for women, ≤2 for men (or less); abstinence preferred during pregnancy and for some medical conditions; no safe level for cancer risk. (5) Sleep: 7-9 hours/night for adults; sleep hygiene practices; address sleep apnea and insomnia. (6) Stress management: mindfulness, exercise, social connection, hobbies, therapy when needed. (7) Social connections: strong social relationships reduce all-cause mortality. (8) Preventive care: annual physical (or every 1-3 years per age), screenings, immunizations, dental care. (9) Sun protection: sunscreen, protective clothing, shade. (10) Safety: seatbelts, helmets, fall prevention, gun safety. These factors prevent leading causes of death: heart disease, cancer, stroke, COPD, diabetes complications, accidents.

Colorectal cancer screening guidelines updated by ACS in 2018 and USPSTF in 2021 to lower age from 50 to 45 due to increased CRC incidence in younger adults. Screening options for average-risk adults age 45-75: (1) Colonoscopy every 10 years — gold standard; can identify and remove polyps in one procedure; requires prep and sedation; (2) Fecal Immunochemical Test (FIT) annually — non-invasive stool test for blood; requires colonoscopy if positive; (3) FIT-DNA (Cologuard) every 1-3 years — stool test detecting DNA markers and blood; requires colonoscopy if positive; (4) Sigmoidoscopy every 5 years — examines only lower colon; (5) CT Colonography (virtual colonoscopy) every 5 years — imaging study; requires colonoscopy if abnormal; (6) Sigmoidoscopy plus annual FIT. Choice depends on patient preference, ability to undergo prep/sedation, cost, insurance, family history. Higher-risk individuals (family history, inflammatory bowel disease, certain genetic syndromes) need earlier and more frequent screening. After 75: individualized decision; ACS suggests through age 85 may benefit. Patient education: prep is the worst part of colonoscopy for most; many adults avoid screening due to anxiety; nurses can normalize the procedure and address concerns. Stool-based tests offer alternatives for those who decline colonoscopy.

Hypertension is often asymptomatic ('silent killer'); patient education is critical because behavior change drives outcomes. Key teaching: (1) DASH Diet (Dietary Approaches to Stop Hypertension) — emphasizes fruits, vegetables, whole grains, low-fat dairy, lean protein; limits saturated fat, total fat, sodium, sweets; demonstrated to lower BP significantly; (2) Sodium reduction — 1500-2300 mg/day; read food labels (sodium often hidden in processed foods); cooking from scratch with less salt; avoiding fast food; (3) Weight management — even 5-10 pound weight loss can significantly reduce BP; (4) Physical activity — 150 minutes moderate aerobic activity weekly; (5) Alcohol moderation — ≤1 drink/day for women, ≤2 for men; (6) Smoking cessation — smoking acutely raises BP and damages vasculature; (7) Stress management; (8) Medication: take as prescribed, even when feeling well; do not stop abruptly; report side effects to prescriber; common side effects vary by class (ACE inhibitors: cough; calcium channel blockers: edema; diuretics: increased urination, electrolyte changes; beta-blockers: fatigue, bradycardia, sexual dysfunction); (9) Home BP monitoring — accurate technique, log readings, target generally <130/80 (varies); (10) Symptoms requiring immediate attention — severe headache, vision changes, chest pain, neurological symptoms (could indicate hypertensive crisis or stroke). Long-term untreated hypertension causes stroke, MI, heart failure, kidney disease, retinopathy.
