SECTION 1: GROWTH & DEVELOPMENT (Questions 1-25)
1. A nurse is assessing a 2-month-old infant. Which finding should the nurse report
to the provider as a developmental delay?
A) Does not roll from back to side
B) Does not hold head up when prone
C) Does not reach for objects
D) Does not sit without support
Answer: B – Does not hold head up when prone
Rationale: By 2 months, an infant should be able to lift their head when placed in a prone
,position. Rolling back to side occurs around 4 months, reaching for objects around 3-4
months, and sitting without support around 6-8 months.
2. A mother asks when her infant can begin eating solid foods. The nurse's best
response is:
A) "You can start at 2 months with rice cereal in the bottle."
B) "Around 6 months, when the infant has good head control and can sit with support."
C) "At 4 months with pureed meats for iron."
D) "Not until the first birthday."
Answer: B – "Around 6 months, when the infant has good head control and can sit
with support."
Rationale: The AAP recommends introducing solid foods around 6 months when the infant
shows readiness signs including good head control, ability to sit with support, and loss of
the extrusion reflex. Iron-fortified cereals are typically first foods.
3. Which of the following fine motor skills should a 9-month-old infant demonstrate?
A) Builds a tower of 2 blocks
, B) Uses a pincer grasp
C) Scribbles spontaneously
D) Turns pages in a book
Answer: B – Uses a pincer grasp
Rationale: The pincer grasp (using thumb and forefinger) develops around 9 months.
Building a 2-block tower occurs at 15 months, scribbling at 15-18 months, and turning book
pages at 18 months.
4. A nurse is providing anticipatory guidance to parents of a 4-year-old. Which
statement by the parents indicates understanding?
A) "We should expect our child to have imaginary friends."
B) "Our child should be able to ride a bicycle."
C) "It's time for our child to stop napping completely."
D) "Our child should understand abstract concepts."
Answer: A – "We should expect our child to have imaginary friends."
Rationale: Imaginary friends and magical thinking are common and developmentally
appropriate in preschoolers (ages 3-5). Bicycle riding (two-wheeler) is typical at age 6-7,
napping may continue, and abstract thinking develops in adolescence.
