Midwife Licensure Exam Infant & Child Health (Growth, Development & IMCI) — Growth & Development Across ChildhoodRevision Notes

Exam Tips

• If an NLE item asks which direction development proceeds, the answer is BOTH cephalocaudal AND proximodistal — they operate together.
• When a question describes a child skipping a milestone (e.g., walks without ever crawling), know that the sequence can occasionally vary but still reflects normal variability.
• Questions about 'what the nurse should tell the mother' about development often want you to say: 'Development follows a predictable sequence but the rate is individual.'

Key Points

• Growth = increase in physical size (weight, height, head circumference) — measurable and quantitative.
• Development = progressive acquisition of function and skills (motor, language, cognitive, psychosocial) — qualitative.
• Cephalocaudal direction: head control develops BEFORE trunk control, which develops BEFORE leg control. Example: infant holds head up → sits → walks.
• Proximodistal direction: from midline outward. Shoulder control develops BEFORE hand control; palmar grasp develops BEFORE pincer grasp.
• Development is continuous, orderly, sequential, and predictable in ORDER — but the RATE varies between individual children.
• Simple to complex and general to specific: babbling before words; whole-hand grasping before fine pincer.
• Critical/sensitive periods exist when a child is most receptive to acquiring a particular skill.
• NLE clinical implication: always compare a child's pattern against the expected sequence, not just the rate.

Principles of Growth and Development

Common Mistakes

• Confusing growth (physical size) with development (function/skill) — NLE distractors exploit this.
• Assuming all children must reach milestones at the exact listed age — remember, RATE varies; SEQUENCE does not.
• Forgetting that cephalocaudal and proximodistal are two separate but simultaneous patterns.

Formulas

Exam Tips

• Memorize the TRIPLES at 12 months rule — it is one of the most frequently tested NLE growth facts.
• When an NLE scenario mentions a tense or bulging fontanelle, think ICP — link this to findings like high-pitched cry and vomiting.
• For fontanelle closure: Posterior = 2 months; Anterior = 12–18 months. Use the mnemonic 'PA' — Posterior first, Anterior later.

Key Points

• Average newborn weight: 3–3.5 kg (3,000–3,500 g). Physiologic weight loss of 5–10% in first few days; regained by 10–14 days.
• WEIGHT RULE: Doubles by ~4–6 months → Triples by 12 months (1 year) → Quadruples by ~24 months (2 years).
• Average newborn length: ~50 cm. Length increases by ~50% by 1 year (~75 cm). Birth length doubles by ~4 years.
• Average newborn head circumference (HC): ~34–35 cm. HC > chest circumference at birth; they equalize at ~1–2 years.
• Head circumference increases ~1 cm/month in the first year.
• POSTERIOR fontanelle (triangular) closes by ~2 months (6–8 weeks).
• ANTERIOR fontanelle (diamond-shaped) closes by ~12–18 months.
• Bulging anterior fontanelle = increased intracranial pressure (↑ICP) — URGENT.
• Sunken fontanelle = dehydration — requires prompt intervention.
• First deciduous teeth erupt at ~6 months (lower central incisors FIRST).
• Formula for number of teeth: Age in months − 6 = number of teeth (e.g., 12 months: 12 − 6 = 6 teeth).
• All 20 deciduous teeth present by ~2.5–3 years.

Section Title

Physical Growth Parameters — The Numbers You Must Memorize

Common Mistakes

• Mixing up which fontanelle closes FIRST — it is the POSTERIOR (by 2 months), not the anterior.
• Confusing 'triples by 12 months' with 'doubles by 12 months' — weight DOUBLES at 4–6 months, TRIPLES at 12 months.
• Forgetting that bulging fontanelle = ICP and sunken = dehydration — the NLE will test clinical interpretation, not just anatomy.
• Applying the teeth formula incorrectly — it is age (months) MINUS 6, starting at 6 months.

Exam Tips

• Use this mnemonic for Erikson: 'Trust, Autonomy, Initiative, Industry, Identity' — TAIIII — mapped to Infant, Toddler, Preschool, School-age, Adolescent.
• For Piaget, associate: Baby Senses (Sensorimotor 0–2), Pretend Play Ego (Preoperational 2–7), Concrete Thinkers (7–11), Formal Abstract (11+).
• For Freud: 'Old Age People Like Growing' — Oral, Anal, Phallic, Latency, Genital.
• NLE items often present a behavior and ask WHICH theorist's stage it reflects — know all three frameworks for the same age group simultaneously.
• If an NLE item asks 'what is the BEST nursing action for a hospitalized toddler,' the answer almost always involves offering limited choices (supporting autonomy).

Key Points

• THREE major theorists tested: Erikson (psychosocial), Piaget (cognitive), Freud (psychosexual).
• ERIKSON — Infant (0–1 yr): Trust vs Mistrust. Nursing: consistent caregiving, prompt response to crying.
• ERIKSON — Toddler (1–3 yr): Autonomy vs Shame and Doubt. Behavior: negativism, 'No!', temper tantrums, toilet training. Nursing: offer limited choices.
• ERIKSON — Preschool (3–6 yr): Initiative vs Guilt. Behavior: curious, imaginative play, questions. Nursing: encourage exploration, avoid excessive criticism.
• ERIKSON — School-age (6–12 yr): Industry vs Inferiority. Behavior: wants to achieve, complete tasks, be competent. Nursing: encourage hobbies, collections, schoolwork.
• ERIKSON — Adolescent (12–18 yr): Identity vs Role Confusion. Behavior: peer-focused, questions identity. Nursing: respect privacy, support peer relationships.
• PIAGET — Sensorimotor (0–2 yr): learns through senses and movement. KEY milestone: Object permanence at ~8–9 months.
• PIAGET — Preoperational (2–7 yr): egocentrism, magical thinking, animism, centration. Cannot yet conserve.
• PIAGET — Concrete Operational (7–11 yr): logical reasoning about concrete objects, masters conservation and classification.
• PIAGET — Formal Operational (11 yr+): abstract, hypothetical, deductive reasoning.
• FREUD — Oral (infant) → Anal (toddler) → Phallic/Oedipal (preschool) → Latency (school-age) → Genital (adolescent).
• Object permanence (Piaget, ~8–9 months) explains WHY peek-a-boo is enjoyed and WHY separation anxiety begins around 8–10 months.

Section Title

Developmental Theorists — Erikson, Piaget, and Freud

Common Mistakes

• Confusing Piaget's Preoperational stage (2–7 yrs) with Erikson's Initiative vs Guilt stage (3–6 yrs) — they overlap in age but describe different dimensions.
• Placing school-age children in the Preoperational stage — school-age (7–11 yrs) is Concrete Operational.
• Forgetting that Freud's Phallic stage corresponds to the PRESCHOOLER (3–6 yrs), not the toddler.
• Confusing the Oral stage with the Anal stage — Oral is INFANT, Anal is TODDLER.
• Mixing up Identity (adolescent) with Industry (school-age) — remember: school-age works and produces (Industry); adolescent asks 'Who am I?' (Identity).

Exam Tips

• Use the '3-4-6-9-12-15' rule for gross motor milestones: smile at 2, rolls at 4, sits supported at 6, sits unsupported at 7–8, crawls/pincer at 9, stands at 12, walks well at 15.
• For tricycle-hop-skip, think: '3-4-5' — Tricycle at 3, Hop (one foot) at 4, Skip at 5.
• A question mentioning a child who 'walks independently' is likely describing a 15-month-old, not a 12-month-old.
• Language at 2 years = 2-word phrases + ~50 words + half understandable to strangers — a complete package to memorize.

Key Points

• 2 months: Lifts head when prone; SOCIAL SMILE appears (key milestone).
• 4 months: Rolls from prone (front) to supine (back); no head lag; steady head control.
• 6 months: Sits WITH support; rolls BOTH ways; palmar grasp; transfers objects hand to hand.
• 7–8 months: Sits WITHOUT support (unsupported sitting).
• 9 months: CRAWLS; NEAT PINCER GRASP develops (thumb and forefinger).
• 10 months: PULLS TO STAND; cruises along furniture.
• 12 months: STANDS ALONE; may take first steps; 2–3 meaningful words besides mama/dada.
• 15 months: WALKS ALONE WELL.
• 18 months: RUNS stiffly; climbs stairs with help; 10–15 words.
• 2 years: Walks up and down stairs (both feet per step); runs well; ~50+ words; 2-WORD PHRASES; ~50% of speech understandable to strangers.
• 3 years: RIDES TRICYCLE; climbs stairs alternating feet; 3-word sentences; ~75% of speech understandable.
• 4 years: HOPS ON ONE FOOT; throws overhand; asks many 'why' questions.
• 5 years: SKIPS; JUMPS ROPE; hops on alternate feet; ~100% of speech understandable.
• Language: 12 months ~2 words; 2 years ~50 words + 2-word phrases; 3 years ~250+ words + sentences.
• Fine motor progression: palmar grasp (4–6 months) → neat pincer grasp (~9–10 months) → scribbling (~15–18 months) → copying a circle (~3 years) → copying a square (~4–5 years).

Section Title

Motor and Language Developmental Milestones

Common Mistakes

• Confusing 'sits with support' (6 months) with 'sits without support' (7–8 months) — a frequent NLE distractor.
• Placing the pincer grasp at 6 months instead of 9 months.
• Saying a child walks at 12 months — at 12 months they STAND ALONE and may take a few steps; walking WELL is at 15 months.
• Forgetting that tricycle riding is 3 years, hopping is 4 years, and skipping/jumping rope is 5 years — these are chronically confused.

Exam Tips

• Group most primitive reflexes together: Moro, rooting, sucking, palmar grasp, and tonic neck ALL disappear by ~3–4 months.
• Plantar grasp is the exception — it lasts until 8–10 months.
• Babinski is the only one that is NORMAL with an upgoing response in infants — all others should diminish, not persist.
• Asymmetric Moro in a newborn after a difficult delivery → think brachial plexus injury (Erb's palsy) or clavicle fracture — frequently tested in neonatal nursing scenarios.

Key Points

• Primitive reflexes are present at birth due to lower brainstem dominance; they disappear as the cortex matures.
• ABSENCE at birth OR PERSISTENCE beyond expected age = neurologic red flag.
• MORO (startle) reflex: sudden noise/movement → arms abduct and extend, then embrace. Disappears by ~3–4 months.
• ROOTING reflex: stroke the cheek → head turns toward stimulus (assists feeding). Disappears ~3–4 months.
• SUCKING reflex: object at lips → sucking motion. Disappears ~3–4 months (while awake).
• PALMAR GRASP: object placed in palm → fingers curl and grip. Disappears ~3–4 months.
• PLANTAR GRASP: pressure to sole of foot → toes curl downward. Disappears ~8–10 months.
• TONIC NECK (fencing) reflex: head turned to side → same-side arm and leg extend, opposite side flexes. Disappears ~3–4 months.
• BABINSKI reflex: stroke the lateral sole upward → toes FAN OUT (dorsiflex/up-going). NORMAL in infants until ~1–2 years; ABNORMAL (and concerning) in children >2 years and adults.
• STEPPING/DANCE reflex: held upright with feet on surface → stepping movements. Disappears ~4–8 weeks.
• KEY clinical points: Persistence of Moro or tonic-neck reflex beyond 6 months suggests cerebral pathology.
• Babinski is the ONLY primitive reflex that is NORMALLY present (up-going toes) in infants — this is the reverse of the adult normal response.

Definitions

Section Title

Newborn Primitive Reflexes

Common Mistakes

• Thinking that an upgoing Babinski in an infant is ABNORMAL — it is NORMAL until ~1–2 years.
• Stating that all primitive reflexes disappear at the same age — palmar and plantar grasp disappear at DIFFERENT times (palmar at 3–4 months; plantar at 8–10 months).
• Forgetting that absence of a reflex at birth is just as concerning as persistence beyond the expected age.
• Confusing the Moro and startle reflex — Moro specifically involves the arms-out-then-embrace pattern; it is more specific than a general startle.

Exam Tips

• Use this sequence: Solitary → Parallel → Associative → Cooperative (SPAC) mapped to Infant → Toddler → Preschool → School-age.
• NLE scenarios that ask 'which toy is most appropriate' require you to consider BOTH the developmental stage AND safety (no small parts for <3 years).
• Therapeutic play items: encourage the use of a doll or puppet to explain procedures to preschoolers — this is a standard NLE 'best nursing action' answer.

Key Points

• Play is a critical nursing assessment parameter and a therapeutic tool — 'play is the work of childhood.'
• SOLITARY PLAY — Infant: plays alone; does not seek other children. Appropriate toys: mobiles, rattles, teething rings (must be mouthing-safe).
• PARALLEL PLAY — Toddler: plays ALONGSIDE other children but NOT with them; no sharing or interaction. Appropriate toys: push-pull toys, blocks, simple puzzles.
• ASSOCIATIVE PLAY — Preschool: plays WITH others but without formal rules or assigned roles; includes imitative/dramatic play (dress-up, pretend). Appropriate toys: tricycles, play kitchen, art supplies.
• COOPERATIVE PLAY — School-age: organized, rule-based, team activities; includes board games, sports, collections. Promotes industry and social competence.
• THERAPEUTIC PLAY is used in hospital settings to allow children to express fears, understand procedures, and reduce anxiety (e.g., letting a preschooler handle medical equipment on a doll before a procedure).
• Adolescents engage in competitive sports and peer group activities; peer acceptance is central to identity formation.

Section Title

Play by Age — The Work of Childhood

Common Mistakes

• Confusing associative play (preschool) with cooperative play (school-age) — cooperative has RULES and ROLES; associative does not.
• Selecting parallel play for preschoolers — parallel play is specifically the TODDLER stage.
• Forgetting that toy safety is age-specific — mouthing-safe toys for infants/toddlers; no small parts.

Exam Tips

• The NLE frequently asks: 'When should complementary feeding begin?' — Answer: 6 months, while continuing breastfeeding.
• If a question asks about a food to AVOID for an infant under 12 months, honey and whole cow's milk are the two classic answers.
• Philippine-specific programs (Garantisadong Pambata, Operation Timbang) may appear in community health-linked NLE items — know what they screen for.

Key Points

• EXCLUSIVE BREASTFEEDING (EBF) for the first 6 months — this is DOH, WHO, and UNICEF policy. No water, no formula, no other food.
• Complementary feeding begins at 6 months while breastfeeding continues up to 2 years and BEYOND (DOH/WHO recommendation).
• Introduce ONE new food at a time; wait 3–7 days before introducing the next food to detect allergies.
• Start with iron-fortified cereal (rice/oatmeal) → then pureed vegetables and fruits → then pureed meats.
• NEVER give HONEY to infants under 12 months — risk of infant botulism (Clostridium botulinum spores).
• Avoid WHOLE COW'S MILK as main drink before 12 months — immature renal function and lack of iron.
• Choking hazard foods for toddlers: whole grapes, raw carrots, nuts, popcorn, hot dogs (round slices) — require supervision or cutting.
• Philippine context: DOH programs include Garantisadong Pambata (health packages for children 0–14 years), Operation Timbang (weighing for malnutrition screening), ECCD (Early Childhood Care and Development).
• IMCI (Integrated Management of Childhood Illness) and growth monitoring at RHUs use WHO growth standards.
• Under RA 9173 (Philippine Nursing Act of 2002), nurses perform health education on infant nutrition as part of their independent nursing function.

Definitions

Section Title

Nutrition Milestones and Filipino DOH Context

Common Mistakes

• Stating that complementary feeding begins at 4 months — current DOH/WHO policy is 6 months.
• Forgetting that EBF means NO WATER — many test-takers think water is acceptable; it is NOT during EBF.
• Allowing honey after 6 months just because complementary feeding starts — honey is prohibited for the ENTIRE FIRST YEAR.
• Confusing the order of complementary food introduction — iron-fortified cereal FIRST, then vegetables/fruits, then meats.

Exam Tips

• NLE items on anticipatory guidance will often describe a child's current or upcoming age and ask WHICH safety concern to address — match the age to the primary risk.
• For infants: the answer about safety is almost always 'back to sleep' (supine position) or aspiration/choking prevention.
• For toddlers: the answer is almost always about poisoning or drowning prevention.
• For adolescents: the leading cause of death is MVA — this will appear in health promotion items.

Key Points

• Anticipatory guidance = teaching parents about EXPECTED developmental milestones and the INJURY RISKS associated with new abilities — given BEFORE the child reaches that stage.
• INFANT (0–12 months): Risks include SIDS, aspiration/choking, falls, suffocation. Teach: back-to-sleep (supine), rear-facing car seat, no propped bottles, no small objects in crib, crib safety (no bumpers, firm mattress).
• TODDLER (1–3 years): Mobile and curious; risks include POISONING, DROWNING, FALLS, BURNS. Teach: poison control storage, cabinet locks, stair gates, outlet covers, constant supervision near any water source (baldi, pail, pool).
• PRESCHOOL (3–6 years): Increasing independence; risks include TRAFFIC/ROAD INJURY, DROWNING, BURNS, STRANGER DANGER. Begin teaching: road safety (look both ways), swimming lessons, stranger safety ('no touch' rules).
• SCHOOL-AGE (6–12 years): Sports and bike activities; risks include SPORTS INJURIES, BICYCLE ACCIDENTS, DROWNING. Teach: HELMETS, seat belts, water safety rules, fire escape plans.
• ADOLESCENT (12–18 years): Risk-taking behavior; risks include MOTOR VEHICLE CRASHES (leading cause of death), SUBSTANCE USE, SEXUAL RISK. Counsel on: safe driving, seatbelts, avoiding alcohol/drugs, sexual health and contraception.

Definitions

Section Title

Anticipatory Guidance and Safety by Age Group

Common Mistakes

• Teaching parents about a risk AFTER the child is already at that developmental stage — anticipatory guidance is given BEFORE the stage.
• Overlooking that drowning in TODDLERS frequently occurs in small containers (baldi, basins) — not just pools.
• Forgetting that MVA (motor vehicle accident) is the LEADING CAUSE of death in adolescents — not substance abuse or violence.
• Recommending prone sleeping for infants — ALWAYS supine ('back to sleep') to reduce SIDS.
