Developmental Stages and Aging: Practice Questions & Explanations

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).

Normal aging changes affect every body system and influence care: (1) Vision: presbyopia (near vision decline starting ~40), cataracts, glaucoma risk, decreased adaptation to dark and glare; (2) Hearing: presbycusis (high-frequency hearing loss); (3) Cardiovascular: decreased cardiac output, increased BP variability, slower heart rate response to exercise; (4) Respiratory: decreased lung elasticity and reserve, decreased ciliary function (increased infection risk); (5) GI: decreased gastric acid (affecting iron, B12, calcium absorption), slower peristalsis (constipation risk), decreased appetite; (6) Renal: decreased GFR (drug dosing implications); (7) Musculoskeletal: decreased muscle mass (sarcopenia), decreased bone density (osteoporosis), joint changes, decreased flexibility; (8) Neurological: slower reaction time, decreased balance, mild changes in short-term memory normal (dementia is NOT normal aging); (9) Skin: thinning, decreased elasticity, slower wound healing, decreased sensation; (10) Immune: less robust response to infections and vaccines (immunosenescence); (11) Thermoregulation: less effective response to heat/cold; (12) Pharmacokinetics: changes in drug absorption, distribution, metabolism, excretion — most older adults need lower drug doses than younger adults. Polypharmacy is common and concerning. Nurses should distinguish normal aging from pathology — confusion, falls, weight loss, incontinence are not normal aging but signal medical issues. Beers Criteria identify potentially inappropriate medications in older adults.

Car seat recommendations (AAP and NHTSA): (1) Rear-Facing: as long as possible; until the child reaches the rear-facing seat's maximum height or weight limit (typically 40-50 pounds in convertible seats); minimum until age 2; rear-facing significantly reduces injury in crashes by 5x compared to forward-facing in young children; (2) Forward-Facing with Harness: when the child outgrows rear-facing limits; use until reaching the harness seat's maximum height or weight (often 65-80 pounds); (3) Belt-Positioning Booster: when the child outgrows the harness; use until the seat belt fits properly without the booster (typically 4'9' tall, age 8-12); (4) Seat Belt Alone: when the child can sit with back against the seat, knees bend at the seat edge, lap belt low across thighs, shoulder belt across chest (not neck), and stay this way for the entire ride. Back seat until age 13 — front airbags are dangerous to children. Booster seats are commonly skipped — they significantly reduce injury and should be used until belt fits properly. Properly used car seats can reduce death by 71% for infants and 54% for toddlers. Nurses in pediatric, emergency, and well-child settings should reinforce proper use; many hospitals have car seat clinics for installation checks.

At AGE 6 (school-age entry), certain developmental skills are expected. RED FLAGS warranting referral include: LANGUAGE: difficulty following two-step directions; very limited vocabulary for age; significant articulation problems that make speech hard to understand; COGNITIVE: inability to recognize letters or write their name; difficulty understanding simple concepts; FINE MOTOR: inability to hold a pencil, copy simple shapes, or button clothing; GROSS MOTOR: clumsiness significantly beyond peers; SOCIAL-EMOTIONAL: complete inability to interact with peers; no interest in other children; extreme behavioral problems beyond typical child behavior. EXPECTED SKILLS at 6 years: LANGUAGE: 2,000+ word vocabulary; can tell a story; follows multi-step instructions; COGNITIVE: begins reading simple words; understands counting; recognizes name in print; understands cause and effect; FINE MOTOR: copies shapes; writes name; uses scissors; draws recognizable figures; GROSS MOTOR: runs, jumps, hops, skips; rides a bicycle (often); catches a ball reliably; SOCIAL: plays cooperatively with other children (parallel play transitions to cooperative play around ages 4-6); understands rules in games; has friends. NORMAL VARIATION: children develop at different rates; occasional difficulty is normal; tying shoes is a fine motor skill many 6-year-olds are still learning; preferring one close friend is normal; difficulty losing is normal. REFERRAL CONSIDERATIONS: developmental screening tools (Ages and Stages Questionnaire, Denver II); early intervention is key — the earlier developmental delays are identified and addressed, the better the outcomes. PN ROLE: document developmental assessments; report concerns to RN/provider; provide anticipatory guidance to families.

Commonly taught developmental theory (such as Erikson's stages) identifies the primary psychosocial task of infancy (approximately birth to 1 year) as developing trust versus mistrust — the infant learns to trust caregivers when their basic needs are met consistently and lovingly. Identity formation is the task of adolescence, generativity belongs to middle adulthood, and career achievement is an adult concern. Understanding broad psychosocial developmental tasks by stage supports anticipatory guidance and family teaching. Recognizing the developmental focus of each life stage at a high level is a standard growth-and-development concept. (This reflects widely taught theory; verify against current NCLEX prep materials.)

Developmentally appropriate care for a preschool-age child includes using simple, concrete language, offering choices when appropriate to support their growing autonomy, incorporating play (a key way young children learn and cope), and involving the parents. Preschoolers cannot process detailed abstract explanations and should not be treated as adults. Tailoring communication and care to the child's developmental level — and partnering with parents — improves understanding and cooperation. Understanding developmentally appropriate approaches for children is a standard health-promotion concept. (This reflects general principles; verify against current NCLEX prep materials.)

A general principle of growth and development is that development tends to follow predictable sequences and directions (for example, head-to-toe and center-outward progression in motor development), but the rate of development varies among individual children. Therefore, findings are interpreted in context rather than expecting every child to reach milestones at identical times, while still noting significant delays for further evaluation. Understanding that development is sequential yet individually variable is a foundational concept that guides assessment and anticipatory guidance. (This reflects general principles; specific milestone assessment should be verified against current authoritative guidance and NCLEX prep materials.)
