Growth and Development (Questions 1–10)
1. At what age does a typically developing infant
begin to sit unsupported?
A. 2 months
B. 4 months
C. 6 months
D. 9 months
Answer: C. 6 months
Rationale: Most infants achieve unsupported sitting
by around 6 months as trunk muscles strengthen and
postural control improves (CDC).
2. Which play activity is most appropriate for a
3-year-old child?
A. Solitary play
B. Parallel play
C. Cooperative play
D. Team sports
Answer: B. Parallel play
Rationale: Preschoolers (2–4 years) engage in
parallel play—playing alongside peers without direct
interaction—which supports social development
(CDC).
3. A 9-month-old infant should typically be able to:
A. Crawl and pull to stand
B. Walk independently
C. Say “mama” and “dada” specifically
, D. Use a spoon and fork
Answer: A. Crawl and pull to stand
Rationale: By 9 months, gross motor skills include
crawling and pulling to stand; first words (“mama,”
“dada”) usually appear by 10–12 months (CDC).
4. Which of the following is a red flag in toddler
language development?
A. Using two-word phrases by 2 years
B. Imitating speech sounds by 18 months
C. No single words by 18 months
D. Pointing to desired objects by 15 months
Answer: C. No single words by 18 months
Rationale: Lack of any single words by 18 months
suggests a language delay and warrants further
evaluation (Pediatrics Publications).
5. Erikson’s stage for the school-age child focuses
on:
A. Trust vs. mistrust
B. Autonomy vs. shame and doubt
C. Initiative vs. guilt
D. Industry vs. inferiority
Answer: D. Industry vs. inferiority
Rationale: School-age children (6–12 years) strive for
competence in skills and peer approval,
characterizing the industry vs. inferiority stage (CDC).
6. Which growth chart is most appropriate for
plotting head circumference?
A. BMI-for-age
, B. Length/height-for-age
C. Weight-for-age
D. Head circumference-for-age
Answer: D. Head circumference-for-age
Rationale: Head circumference charts track brain
growth, especially important in infants <36 months
(CDC).
7. At 15 months, a child should be expected to:
A. Walk up stairs alternating feet
B. Build a tower of two blocks
C. Throw a ball overhand
D. Speak in three-word sentences
Answer: B. Build a tower of two blocks
Rationale: Fine motor skill of stacking two blocks
emerges by 15 months (CDC).
8. Piaget’s sensorimotor stage ends when:
A. Object permanence is achieved
B. Magical thinking begins
C. Abstract reasoning starts
D. Logical operations develop
Answer: A. Object permanence is achieved
Rationale: Sensorimotor stage (birth–2 years)
culminates with understanding that objects continue
to exist when out of view (CDC).
9. Which reflex should disappear by 4–6 months?
A. Moro reflex
B. Rooting reflex
C. Babinski reflex
