1. During a routine developmental assessment of a 4-month-old infant,
which milestone would the nurse expect to observe?
 A) Sitting without support
 B) Rolling from back to stomach
 C) Babbling and cooing
 D) Pincher grasp development
 Answer: C) Babbling and cooing
 Rationale: By 4 months of age, infants typically engage in babbling and
cooing as a form of early language development. Sitting without support
and rolling from back to stomach are milestones usually achieved around
6 months, while the pincher grasp develops around 9 months.
2. A nurse is assessing a 2-year-old child during a well-child visit. Which
developmental achievement is most characteristic of this age group?
 A) Using complete sentences
 B) Walking up stairs with alternating feet
 C) Recognizing gender identity
 D) Engaging in parallel play
 Answer: D) Engaging in parallel play
 Rationale: Two-year-old children often play alongside other children
(parallel play) but do not yet engage in cooperative play. Complete
sentences are typical of older toddlers, walking up stairs with alternating
feet is a skill developed around 3 years, and recognizing gender identity
occurs later in preschool years.
3. In evaluating the growth patterns of a 6-year-old child, the nurse
recognizes that school-age children typically:
 A) Triple their birth weight by the first year
 B) Gain about 2 kg per year
 C) Experience rapid growth comparable to infancy
 D) Show decreased appetite compared to toddlerhood
 Answer: B) Gain about 2 kg per year
 Rationale: School-age children generally gain about 2 kg per year.
Tripling birth weight occurs by the first year, rapid growth is seen inÂ
