# SECTION 1: GROWTH AND DEVELOPMENT (Questions 1–40)
**1.** A nurse is educating a parent about infant developmental
milestones. Which milestone would the nurse expect an 8-month-old
infant to demonstrate?
A) Walks independently
B) Sits unsupported
C) Uses a pincer grasp
D) Says “mama” specifically
**Correct Answer:** B – Sits unsupported
**Rationale:** An 8-month-old infant can sit without support, transfer
objects between hands, and babbles (“baba,” “mama” nonspecifically).
The pincer grasp develops around 9-10 months.
**2.** A 3-year-old child is having a tantrum in the waiting room. The
parent asks the nurse why the child is behaving this way. The nurse
explains that this is most likely due to:
A) Lack of discipline
B) Frustration with limited language skills
C) Oppositional defiant disorder
D) Fatigue only
,3|Page
**Correct Answer:** B – Frustration with limited language skills
**Rationale:** Toddlers and young preschoolers (ages 2-4) lack the
language to fully express their needs, leading to frustration tantrums.
This is normal for the developmental stage.
**3.** A nurse is assessing a 12-month-old infant during a well-child
visit. Which finding requires further evaluation?
A) Birth weight tripled
B) Birth length increased by 50%
C) Able to stand with assistance
D) Anterior fontanel that remains palpable
**Correct Answer:** D – Anterior fontanel that remains palpable
**Rationale:** The anterior fontanel should close by 12-18 months. A
palpable fontanel at 12 months may be normal but requires continued
monitoring. The other options are expected.
**4.** According to Erikson, a preschooler (ages 3-6) is in which
psychosocial stage?
A) Trust vs. Mistrust
B) Autonomy vs. Shame and Doubt
C) Initiative vs. Guilt
D) Industry vs. Inferiority
, 4|Page
**Correct Answer:** C – Initiative vs. Guilt
**Rationale:** Initiative vs. Guilt is the stage for preschoolers. They
begin to assert power and control over their environment, leading to a
sense of purpose.
**5.** A nurse is teaching a parent about the expected play activities for
a 9-month-old infant. Which toy is most appropriate?
A) Shape sorter
B) Push-pull toy
C) Peek-a-boo cloth book
D) Tricycle
**Correct Answer:** C – Peek-a-boo cloth book
**Rationale:** Infants at 9 months enjoy interactive play such as peek-
a-boo. They enjoy exploring textures. Push-pull toys are for toddlers.
Shape sorters are for older toddlers (15-18 months).
**6.** A mother of a 15-month-old toddler expresses concern that her
child is no longer walking after having mastered it at 12 months. What is
the best response by the nurse?
A) “This is normal toddler behavior.”
B) “You should contact a neurologist immediately.”
C) “Is the child showing any other regression?”
D) “Give the child more time; it’s just a phase.”
