1. The mother of a 15-month-old asks if it’s normal that
her child is not walking independently. What is the nurse’s
best response?
A) “Most walk by 12 months; this is a significant delay.”
B) “Some normal children walk as late as 18 months. Let’s
assess other milestones.”
C) “You should start physical therapy immediately.”
D) “This always indicates a neurological problem.”

,Correct Answer: B
Rationale: Independent walking typically occurs between
12–15 months, with a normal range up to 18 months.
Assessing other milestones first is appropriate before any
intervention or concern.
2. Which statement by a 5-year-old indicates correct
understanding of conservation?
A) “The tall glass has more juice even though you poured
it from the short fat glass.”
B) “If you break my cookie in half, I have more pieces.”
C) “My sister is older so she is taller.”

, D) “The same amount of clay is still the same if you roll it
into a snake.”
Correct Answer: D
Rationale: Conservation is the understanding that quantity
remains the same despite changes in shape/container.
Most children master this in concrete operational stage
(7–11 years). A 5-year-old typically fails conservation,
so answer D is advanced but correct if demonstrated.
3. A 3-year-old insists on wearing the same Batman
costume every day. This behavior is:
A) A sign of autism spectrum disorder
B) Normal ritualistic behavior
