SECTION 1: GROWTH & DEVELOPMENT (INFANT TO ADOLESCENT) Q1 –
Q9
══════════════════════════════════════
Question 1 of 50
A nurse is assessing a 4-month-old infant during a well-child visit. The parent
reports the infant can hold the head steady when upright, bears weight on the
legs when supported, and brings the hands to the midline. The nurse notes the
infant has not yet rolled from prone to supine. Which response by the nurse is
most appropriate?
,2
A. Refer the infant immediately for developmental evaluation due to delayed
rolling
B. Reassure the parent that rolling typically occurs by 6 months and current
milestones are on track
C. Schedule a follow-up visit in 2 weeks to reassess rolling ability
D. Teach the parent tummy time exercises to accelerate motor development
Correct Answer: B
Rationale: Rolling from prone to supine typically emerges between 4 and 6
months, so a 4-month-old who has not yet achieved this skill is still within the
normal developmental window. Head control, weight-bearing, and midline
hand play are all appropriate 4-month milestones that confirm normal
development. Referring for evaluation at this age would be premature and
cause unnecessary parental anxiety. Tummy time is beneficial but not needed
to accelerate development in a child who is already progressing normally.
Question 2 of 50
A nurse is teaching a parent of a 9-month-old infant about language
development. The parent asks when the infant will say the first real word.
Which milestone should the nurse identify as the expected age for a first
meaningful word?
A. 6 months
B. 9 months
C. 12 months
D. 15 months
Correct Answer: C
,3
Rationale: Most infants speak their first meaningful word around 12 months of
age, typically a simple label like "mama" or "dada" with specific reference. At 9
months, infants are usually babbling in strings of consonants but are not yet
producing true words. By 15 months, a delay in word production would
warrant further evaluation, as most children have a vocabulary of several
words by that age. The 12-month mark is the standard developmental
checkpoint for this milestone.
Question 3 of 50
During a routine school physical, a nurse is assessing a 6-year-old child. The
child is able to ride a bicycle, skip on alternating feet, and print several letters.
The child cannot yet tie shoelaces. Which action by the nurse is most
appropriate?
A. Document the finding and refer the child for fine motor evaluation
B. Reassure the parent that shoelace tying typically develops by age 7 to 8
years
C. Recommend occupational therapy to improve finger dexterity
D. Advise the parent to practice tying shoelaces daily for 30 minutes
Correct Answer: B
Rationale: Tying shoelaces is a complex fine motor skill that typically develops
between 7 and 8 years of age, so a 6-year-old who cannot yet perform this task
is still within the expected developmental range. The child is demonstrating
appropriate gross motor skills for age, including bicycle riding and skipping,
which confirms overall motor development is on track. Referring for
occupational therapy or intensive practice would be unnecessary and
potentially stressful for a child who is developing normally. The nurse should
provide anticipatory guidance about when to expect this skill.

Question 4 of 50
A nurse is caring for a 2-week-old newborn in the nursery. The parent asks
when the infant will begin to smile socially rather than reflexively. The nurse
should explain that the social smile typically appears at which age?
A. 2 weeks
B. 4 to 6 weeks
C. 3 months
D. 6 months
Correct Answer: B
Rationale: The social smile, which is a responsive and intentional facial
expression directed at caregivers, typically emerges between 4 and 6 weeks of
age. Before this time, facial movements that appear smile-like are usually
reflexive and not socially directed. By 3 months, the infant should be smiling
readily and engaging in reciprocal social interaction, so waiting until that age
would be a delay. The 6-month mark is well beyond the expected window for
this milestone and would indicate a significant social developmental concern.
Question 5 of 50
A nurse is evaluating a 15-month-old toddler during a well-child visit. The
parent reports the toddler walks independently, says three words, and points
to desired objects. The toddler does not use a spoon. Which response by the
nurse is most appropriate?
A. Recommend a developmental screening tool because self-feeding is delayed
B. Reassure the parent that independent spoon use typically develops by 18
months
