Growth and Development: Practice Questions & Explanations

Erik Erikson's psychosocial stages identify AUTONOMY vs. SHAME AND DOUBT as the primary conflict of toddlerhood (approximately ages 1-3). During this stage the child is developing a sense of personal control and independence. Key behaviors include: insisting on doing things independently ('me do it'); negativism and oppositional behavior ('no'); parallel play (alongside but not yet cooperative with peers); developing self-feeding, walking, and early language skills. Nursing implications: encourage independence within safe limits; offer limited, simple choices ('Do you want the red cup or the blue cup?'); avoid shaming the child for accidents or failures; recognize that toddler negativism is developmentally normal. TRUST vs. MISTRUST is the infant stage (birth to 18 months) — centered on whether the caregiver is reliable and nurturing. INITIATIVE vs. GUILT is the preschool stage (ages 3-6) — the child explores purpose and pursues goals. INDUSTRY vs. INFERIORITY is the school-age stage (ages 6-12) — centered on competence and achievement. LPN/LVNs are expected to understand normal developmental milestones to recognize deviations and provide anticipatory guidance to families. Toddler safety concerns include: choking hazards (foods must be cut small, small toys avoided), falls, poisoning (medications must be locked away), drowning (never leave unattended near water).

By age 2 months, normal developmental milestones include: SOCIAL SMILE (smiling in response to a face or voice — a key early social milestone, distinct from the reflexive newborn smile); HOLDS HEAD UP briefly when placed on the abdomen (prone position); follows objects with eyes past midline; responds to sound; coos and makes vowel sounds; recognizes parent's face and voice. SITTING WITHOUT SUPPORT typically develops around 6-8 months. PULLING TO STAND typically occurs around 8-10 months. WALKING INDEPENDENTLY usually happens around 9-15 months (average 12 months). RED FLAGS at 2 months: no social smile by 2 months; doesn't follow objects with eyes; doesn't react to loud sounds; very floppy tone or very stiff tone; doesn't coo or make sounds. PN role: document milestone assessment during well-child visits; report to RN/provider any delays; provide parents anticipatory guidance about upcoming milestones; reinforce safe sleep (supine position, firm mattress, no soft bedding — 'back to sleep' for SIDS prevention). DEVELOPMENTAL SCREENING tools used in clinical practice include the Denver Developmental Screening Test (Denver II), which assesses four domains: personal-social, fine motor, language, and gross motor. Early intervention referral is recommended when delays are identified.

NOCTURNAL ENURESIS (bedwetting) is very common in young children. Expected timeline for toilet training: DAYTIME DRYNESS — most children achieve by ages 2-3; NIGHTTIME DRYNESS — typically not expected until ages 5-6; NORMAL VARIATION — many children are not consistently dry at night until age 6-7; approximately 15-20% of 5-year-olds and 5% of 10-year-olds still have occasional bedwetting. PRIMARY NOCTURNAL ENURESIS refers to children who have NEVER achieved consistent nighttime dryness; this is distinct from secondary enuresis (a child who was dry for 6+ months and then begins wetting again — which warrants evaluation for: UTI, stress, new sibling, school change, sexual abuse, diabetes). EVALUATION IS WARRANTED if: age 5+ with frequent wetting; daytime wetting; painful urination; polydipsia/polyuria (possible diabetes); symptoms of UTI; recurrence after 6 months of dryness.

Nursing guidance: reassure parents that bedwetting is DEVELOPMENTALLY NORMAL at age 4; avoid punishment or shame (worsens problem and disrupts development); avoid restricting ALL fluids but reduce fluids 1-2 hours before bed; encourage voiding before sleep; use waterproof mattress cover; reward for dry nights (positive reinforcement) but do not punish for wet nights; most children outgrow it without intervention; moisture alarms and desmopressin (DDAVP) are options for persistent enuresis at age 7+.

Pn role: reassure parents; teach developmental expectations; screen for signs that warrant referral.

SCHOOL-AGE NUTRITION is foundational to healthy growth, cognitive function, and lifelong dietary patterns. Key principles:

Balanced diet: use MyPlate as a visual guide — half the plate fruits and vegetables; one quarter whole grains; one quarter lean protein; dairy on the side.

Breakfast: research consistently links eating breakfast to better concentration, memory, and school performance; children who skip breakfast have more behavioral problems and lower academic achievement; limit added sugars (in breakfast cereals, juices, pastries) and provide protein and whole grains.

Fruits and vegetables: aim for 5+ servings daily; varied colors provide different micronutrients.

Whole grains: choose whole wheat bread, oatmeal, brown rice over refined grains.

Lean protein: chicken, fish, beans, eggs, nuts (school-age children need more protein for growth).

Dairy/calcium: critical for bone development during school years; milk, yogurt, cheese or calcium-fortified alternatives.

Limit: added sugars (soft drinks, candy, pastries), excessive sodium (processed/fast foods), saturated fats.

Obesity prevention: approximately 20% of school-age children in the US have obesity, associated with type 2 diabetes, cardiovascular risk, joint problems, social issues; promote physical activity alongside nutrition.

Special needs: iron-rich foods for girls who begin menstruation; calcium and vitamin D throughout growth; if vegetarian/vegan family, assess for B12, iron, zinc adequacy.

Pn teaching tip: involve children in food preparation; avoid labeling foods as 'good' or 'bad' (can create disordered relationships with food); role-model healthy eating.

Jean PIAGET's theory describes four stages of cognitive development. The PREOPERATIONAL STAGE (approximately ages 2-7) is characterized by: EGOCENTRISM — the child cannot take another's perspective; believes others see, think, and feel exactly as they do; demonstrated by Piaget's 'three mountains' task; MAGICAL THINKING — animism (attributing life to inanimate objects), belief that thoughts can cause events; SYMBOLIC/LANGUAGE THINKING — beginning to use symbols (words, pictures) to represent objects; dramatic play; LACK OF CONSERVATION — does not understand that quantity stays the same when appearance changes (pouring water from a short, wide glass to a tall, narrow glass — child says the tall glass has 'more' water); CENTRATION — focuses on only one dimension at a time; IRREVERSIBILITY — cannot mentally reverse actions; TRANSDUCTIVE REASONING — reasoning from specific to specific (if A caused B once, A always causes B). Piaget's full stages: SENSORIMOTOR (birth to 2 years) — learns through senses and motor action; object permanence develops; PREOPERATIONAL (2-7 years) — symbolic thought, egocentrism; CONCRETE OPERATIONAL (7-11 years) — logical thinking with concrete materials, conservation, decentration, reversibility; FORMAL OPERATIONAL (12+ years) — abstract, hypothetical reasoning.

Nursing application: preoperational children may think their illness is punishment for bad thoughts (magical thinking); medical procedures should be explained simply and concretely; allow them to handle equipment when safe; don't assume they understand explanations aimed at adults; they may not report symptoms accurately because of egocentrism; school-age/concrete operational children benefit from logical explanations and hands-on demonstration.

MMR VACCINE SCHEDULE (CDC ACIP recommended):

First dose: 12-15 months of age.

Second dose: 4-6 years of age (school entry).

Catch-up: Children who did not receive MMR on schedule should be vaccinated as soon as possible; adults born after 1957 who lack evidence of immunity should receive 1-2 doses.

Why not before 12 months: Maternal antibodies (IgG passed to the baby across the placenta) interfere with the baby's immune response to live vaccines; these antibodies decline over the first year; by 12 months, most infants have sufficiently low maternal antibody levels for the vaccine to generate an effective immune response; some outbreak situations (international travel, exposure risk) may prompt vaccination at 6-11 months — but this early dose does NOT count toward the series and must be repeated at 12-15 months. MMR PRECAUTIONS (live vaccine): Do NOT administer to immunocompromised individuals (HIV with low CD4 count, cancer treatment, corticosteroid use); do NOT administer during pregnancy (teratogenic risk); avoid pregnancy for 4 weeks after vaccination; may cause fever and mild rash 7-12 days post-injection (expected immune response); egg allergy is not a contraindication unless severe anaphylaxis to egg — consult allergist; TST (tuberculin test) if needed should be done on the same day as MMR or 4-6 weeks later (MMR can suppress tuberculin reaction temporarily).

GROSS MOTOR MILESTONES for walking: SITTING independently: 6-8 months;

Pulling to stand: 8-10 months; CRUISING (walking while holding furniture): 9-12 months; STANDING ALONE briefly: 10-12 months.

First independent steps: 9-12 months (range).

Walking well: 12-15 months (most children).

Red flag: Not walking by 18 months requires developmental evaluation. DENVER DEVELOPMENTAL SCREENING covers motor, language, personal-social, and fine motor milestones.

NCLEX application: Nurses assess developmental milestones at well-child visits; anticipatory guidance helps parents know what to expect; referral when milestones are significantly delayed. Remember the milestones vary — some children walk at 9 months, others at 15 months — the 18-month threshold is the concern threshold, not a pathology diagnosis.

ERIKSON'S STAGES OF PSYCHOSOCIAL DEVELOPMENT: INITIATIVE vs GUILT (ages 3-6, preschool): Children begin to assert themselves — taking initiative in play, pretend play, asking questions, directing activities. When adults encourage initiative, the child develops the virtue of PURPOSE. When adults consistently criticise, punish initiative, or don't allow independent activity, the child develops GUILT about their own impulses and desires.

Nursing application: Preschool hospitalisation — allow children to make some choices (which arm for IV, what colour bandage), play with medical equipment beforehand, encourage pretend play about medical scenarios.

Developmental context: Other stages — Trust vs Mistrust (0-18 months, infancy); Autonomy vs Shame and Doubt (18 months-3 years); Industry vs Inferiority (6-12 years, school age); Identity vs Role Confusion (12-18 years, adolescence).

120°F (49°C) is the recommended maximum water heater setting to prevent scalding burns in children. At 140°F, scalding occurs in 5 seconds; at 120°F, it takes approximately 5 minutes — providing time to react. Young children have thinner, more sensitive skin and cannot react as quickly as adults. This is a standard anticipatory guidance recommendation at well-child visits for families with young children or elderly family members (also at higher scalding risk). LPN role: deliver this preventive education at appropriate well-child visits.

At about 6 MONTHS, typical development includes: SITTING with support (and beginning to sit without support around 6-7 months); rolling over; transferring objects between hands; babbling; and introducing SOLID FOODS (around 6 months, complementary to breast milk/formula). NCLEX-PN health promotion/growth and development. WALKING typically occurs around 12 months; TOILET TRAINING around 2-3 years; SENTENCES around 2-3 years — these would be inappropriate expectations for a 6-month-old. Anticipatory guidance about age-appropriate milestones helps parents support development and recognize concerns. Knowing major developmental milestones by age is a frequently tested health-promotion concept.

Commonly taught developmental theory (such as Erikson's stages) describes the toddler period (approximately ages 1–3) as a time of developing autonomy — the child begins to assert independence, explore, and do things for themselves ('autonomy versus shame and doubt'). Abstract reasoning develops much later (adolescence), and career and retirement concerns belong to adulthood. Understanding general, age-appropriate developmental characteristics — at a high level — supports anticipatory guidance and health teaching for families. Recognizing broad developmental milestones by stage is a standard health-promotion/growth-and-development concept. (This reflects widely taught theory; verify specifics against current NCLEX prep materials.)

A general principle of care across the lifespan is to adapt communication, teaching, and interventions to the client's developmental stage, abilities, and needs — for example, using play and simple language with young children, and respecting autonomy and addressing sensory or cognitive changes with older adults. Treating all clients identically, relying on a single format for everyone, or ignoring developmental differences reduces the effectiveness and safety of care. Tailoring care to developmental stage is a foundational health-promotion concept. (This reflects general principles; verify against current NCLEX prep materials.)

Commonly taught developmental theory (such as Erikson's) describes adolescence as the period in which a major developmental task is establishing a sense of identity ('identity versus role confusion') — exploring who one is and one's values and roles. Developing trust is the task of infancy, learning to walk occurs in early childhood, and retirement adjustment belongs to later adulthood. Understanding broad developmental tasks by life stage — at a high level — helps the nurse provide age-appropriate anticipatory guidance and teaching. Recognizing the developmental focus of adolescence is a standard growth-and-development concept. (This reflects widely taught theory; verify against current NCLEX prep materials.)
