Pediatric Growth & Development Review
At a 2-month well visit, which social milestone is most expected?
1 Plays simple board games
A
Smiles responsively at a caregiver
B
Copies a square
C
Uses two-word phrases
D
Answer: B. Smiles responsively at a caregiver
Explanation: A responsive social smile commonly emerges by about 2 months and reflects early social engagement. Two-word phrases and more complex play occur much later.
Which finding in an infant should prompt the most urgent developmental evaluation?
2 Brief stranger anxiety
A
Loss of previously acquired milestones
B
Preference for a familiar caregiver
C
Occasional startle with loud sounds
D
Answer: B. Loss of previously acquired milestones
Explanation: Developmental regression is a red flag at any age and warrants prompt evaluation. Normal variations in temperament do not carry the same concern.
A term infant's birth weight is expected to approximately double by what age?
3 About 4 to 6 months
A
2 weeks
B
18 months
C
9 months
D
Answer: A. About 4 to 6 months
Explanation: Most healthy term infants double birth weight by roughly 4 to 6 months and triple it by about 12 months. Trends on the growth chart are more important than a single measurement.

100 original questions with the answer and explanation immediately after every question.
Which statement best describes developmental surveillance?
4 It is limited to motor development
A
It is done only when parents request it
B
It replaces formal screening tools
C
It is an ongoing process performed at routine health visits
D
Answer: D. It is an ongoing process performed at routine health visits
Explanation: Developmental surveillance occurs longitudinally and includes parent concerns, history, observation, and review of milestones. Standardized screening is added at recommended
ages or when concerns arise.
According to common pediatric guidance, standardized developmental screening is recommended at which well-child ages?
5 2, 4, and 6 months
A
5, 10, and 15 years
B
9, 18, and 30 months
C
12, 24, and 48 months only
D
Answer: C. 9, 18, and 30 months
Explanation: AAP guidance recommends standardized developmental screening at 9, 18, and 30 months, with additional screening whenever concerns are present.
Autism-specific screening is routinely recommended at which ages?
6 4 and 6 years
A
Birth and 2 months
B
18 and 24 months
C
6 and 9 months
D
Answer: C. 18 and 24 months
Explanation: Autism-specific screening is recommended at the 18- and 24-month visits. Earlier or additional evaluation is appropriate when social-communication concerns arise.

100 original questions with the answer and explanation immediately after every question.
A 6-month-old who was born 8 weeks premature is being assessed for milestones. Which age is most appropriate to use when interpreting
7 development?
Gestational age at delivery forever
A
Bone age
B
Chronologic age only
C
Corrected age
D
Answer: D. Corrected age
Explanation: For children born preterm, corrected age helps interpret early developmental expectations, commonly through about 2 years of age.
Which growth measure is especially important to track during infancy because it reflects brain and skull growth?
8 Head circumference
A
Arm span only
B
Waist circumference only
C
Chest circumference only
D
Answer: A. Head circumference
Explanation: Serial head-circumference measurements are important during infancy and early childhood because abnormal acceleration or deceleration can signal neurologic or cranial concerns.
The posterior fontanel usually closes at approximately what age?
9 Around 12 months
A
Around 3 years
B
At birth in every infant
C
By about 1 to 2 months
D
Answer: D. By about 1 to 2 months
Explanation: The posterior fontanel is small and generally closes within the first couple of months. The anterior fontanel closes later.
