Question 1: Which developmental milestone is typically achieved by a healthy
infant at approximately 6 months of age?
A. Walking independently
B. Pincer grasp development
C. Rolling from back to front
D. Speaking two-word phrases
CORRECT ANSWER: C. Rolling from back to front
Rationale: By 6 months of age, most infants can roll from back to front and front to back,
demonstrating developing gross motor coordination. Walking independently typically
emerges around 12-15 months, pincer grasp develops around 9-12 months, and two-
word phrases generally appear around 18-24 months.
Question 2: According to Erikson's psychosocial theory, the primary developmental
task for toddlers (ages 1-3 years) is:
A. Trust versus mistrust
B. Autonomy versus shame and doubt
C. Initiative versus guilt
D. Industry versus inferiority
CORRECT ANSWER: B. Autonomy versus shame and doubt
Rationale: Erikson identified autonomy versus shame and doubt as the central
psychosocial conflict for toddlers. During this stage, children develop a sense of
personal control and independence through exploration and self-care activities. Trust
versus mistrust applies to infancy, initiative versus guilt to preschool years, and industry
versus inferiority to school-age children.
Question 3: A pediatric nurse is assessing a 4-year-old child's fine motor skills.
Which activity would be developmentally appropriate to expect?
A. Tying shoelaces independently
B. Copying a circle and drawing a person with 2-4 body parts
C. Writing their full name legibly
D. Using scissors to cut complex shapes
CORRECT ANSWER: B. Copying a circle and drawing a person with 2-4 body parts
Rationale: At age 4, children can typically copy a circle and draw a person with 2-4 body
parts, reflecting age-appropriate fine motor and visual-motor integration. Tying
,shoelaces and writing full names usually develop around ages 5-6, while cutting
complex shapes emerges later in the preschool period.
Question 4: Which statement best describes the concept of "cephalocaudal
development" in pediatric growth?
A. Development proceeds from the center of the body outward
B. Development proceeds from head to toe
C. Development occurs in unpredictable spurts
D. Development is uniform across all body systems
CORRECT ANSWER: B. Development proceeds from head to toe
Rationale: Cephalocaudal development refers to the pattern where growth and motor
control develop from the head downward. Infants gain control of their head and neck
before their trunk and legs. This principle explains why babies lift their heads before
sitting, and sit before walking.
Question 5: During a well-child visit, a parent expresses concern that their 9-
month-old is not yet crawling. What is the most appropriate nursing response?
A. "Crawling is essential for brain development; immediate referral is needed."
B. "All infants crawl by 8 months; this indicates a developmental delay."
C. "Some infants skip crawling and proceed directly to walking; let's assess other
milestones."
D. "Crawling should be encouraged with special equipment to prevent delays."
CORRECT ANSWER: C. "Some infants skip crawling and proceed directly to
walking; let's assess other milestones."
Rationale: While crawling typically emerges between 7-10 months, some typically
developing infants bypass crawling and move directly to pulling up, cruising, or walking.
The nurse should conduct a comprehensive developmental assessment rather than
focusing on a single milestone, as variation in motor development patterns is normal.
Question 6: Which growth parameter is most sensitive to acute nutritional
deprivation in infants?
A. Head circumference
B. Length/height
C. Weight
D. Chest circumference
CORRECT ANSWER: C. Weight
Rationale: Weight is the most sensitive indicator of acute nutritional status in infants
because it can fluctuate rapidly with changes in intake, illness, or hydration.
Length/height reflects chronic nutritional status, while head circumference is closely
tied to brain growth and is less responsive to short-term nutritional changes.
,Question 7: According to Piaget's theory of cognitive development, a preschooler
(age 3-5 years) is primarily in which stage?
A. Sensorimotor stage
B. Preoperational stage
C. Concrete operational stage
D. Formal operational stage
CORRECT ANSWER: B. Preoperational stage
Rationale: The preoperational stage (ages 2-7) is characterized by symbolic thinking,
language development, and egocentrism. Children in this stage struggle with
conservation tasks and logical operations but engage in pretend play and use mental
representations. The sensorimotor stage applies to infancy, concrete operational to
school-age, and formal operational to adolescence.
Question 8: A 2-year-old child is brought for a well-child visit. Which language
milestone should the nurse expect to observe?
A. Using 50+ words and combining two words
B. Speaking in complete sentences of 5-6 words
C. Reciting the alphabet
D. Understanding abstract concepts
CORRECT ANSWER: A. Using 50+ words and combining two words
Rationale: By age 2, typically developing children have a vocabulary of approximately 50
words and begin combining two words to form simple phrases (e.g., "more milk,"
"mommy go"). Speaking in complete sentences emerges around age 3-4, while abstract
thinking develops much later in childhood.
Question 9: Which factor is most strongly associated with secure attachment in
infancy?
A. Consistent, responsive caregiving
B. Exposure to multiple caregivers
C. Early enrollment in daycare
D. Use of developmental toys
CORRECT ANSWER: A. Consistent, responsive caregiving
Rationale: Secure attachment develops when caregivers consistently respond to an
infant's cues and needs in a sensitive, timely manner. This responsive interaction helps
infants develop trust and a secure base for exploration. While multiple caregivers and
daycare can be beneficial, the quality of responsiveness is the primary determinant of
attachment security.
Question 10: At what age do most children typically achieve bladder control during
the day?
, A. 12-18 months
B. 18-24 months
C. 2-3 years
D. 4-5 years
CORRECT ANSWER: C. 2-3 years
Rationale: Most children achieve daytime bladder control between 2-3 years of age,
though there is considerable individual variation. Nighttime control often develops later,
typically by age 5-7. Attempts to toilet train before physiological readiness (usually
before 18 months) are often unsuccessful and may cause frustration.
Question 11: Which statement accurately describes the "proximodistal" principle
of development?
A. Growth proceeds from the extremities toward the center of the body
B. Development progresses from the center of the body outward to the extremities
C. Motor skills develop randomly without pattern
D. Cognitive development precedes physical development
CORRECT ANSWER: B. Development progresses from the center of the body
outward to the extremities
Rationale: The proximodistal principle states that development proceeds from the
center of the body outward. Infants gain control of their shoulders and arms before their
hands and fingers, explaining why reaching develops before the pincer grasp. This
principle complements the cephalocaudal pattern in understanding motor
development sequences.
Question 12: A school-age child (8 years old) is being assessed for cognitive
development. Which ability is characteristic of Piaget's concrete operational
stage?
A. Object permanence
B. Conservation of quantity
C. Abstract hypothetical reasoning
D. Egocentric perspective-taking
CORRECT ANSWER: B. Conservation of quantity
Rationale: Conservation—the understanding that quantity remains the same despite
changes in appearance—is a hallmark of the concrete operational stage (ages 7-11).
Object permanence develops in infancy, abstract reasoning emerges in the formal
operational stage (adolescence), and egocentrism is characteristic of the
preoperational stage.
Question 13: Which nutritional recommendation is most appropriate for a 6-month-
old infant beginning complementary feeding?
