Growth & Development Across Pediatric Age Groups – 10 questions
Q1: A nurse is assessing a 4-month-old infant during a well-child visit. Which of the
following gross motor milestones should the infant be able to perform by this age?
A. Rolls from back to side and sits without support.
B. Raises head 90 degrees when prone and rolls from back to abdomen.
C. Sits alone for a brief moment and transfers objects between hands.
D. Walks alone and climbs stairs with assistance.
Correct Answer: B
Rationale: The best answer is raising the head 90 degrees and rolling from back to
abdomen because a 4-month-old infant typically has sufficient head control and is
mastering rolling over. Sitting alone and transferring objects are typically seen around
6-9 months, and walking alone is a 12-month milestone.
Q2: According to Erikson's theory of psychosocial development, which developmental
conflict is a 2-year-old child experiencing?
A. Trust vs. Mistrust
B. Initiative vs. Guilt
C. Industry vs. Inferiority
D. Autonomy vs. Shame and Doubt
Correct Answer: B
Rationale: This aligns with Erikson's stages because the toddler years (1 to 3 years) are
defined by the conflict of initiative versus guilt, where children learn to assert power and
control over their environment through play and exploration. Autonomy vs. Shame and
Doubt corresponds to infancy.
Q3: A parent asks the nurse what toy is most appropriate for a 6-month-old infant who is
just beginning to grasp objects. Which toy selection by the nurse demonstrates
understanding of developmental milestones?
A. A set of alphabet flashcards
B. A rattle and soft blocks
C. A 24-piece puzzle
,D. A coloring book with crayons
Correct Answer: B
Rationale: This choice is correct because infants at this age are developing their palmar
grasp and hand-eye coordination, making rattles and soft blocks ideal for shaking and
grasping. Flashcards, puzzles, and coloring books require fine motor and cognitive skills
not yet developed at 6 months.
Q4: The nurse is reviewing the immunization schedule for a newborn. According to the
current recommendations (2026/2027), which vaccine is typically administered shortly
after birth, preferably within the first 24 hours?
A. MMR (Measles, Mumps, Rubella)
B. Hepatitis B (HepB)
C. Varicella
D. DTaP (Diphtheria, Tetanus, acellular Pertussis)
Correct Answer: B
Rationale: The best answer is Hepatitis B because current guidelines recommend
administering the first dose of the monovalent Hepatitis B vaccine within the first 12
hours after birth, or at least before hospital discharge, to prevent perinatal transmission.
Q5: During a newborn assessment, the nurse elicits the Moro reflex. What is the
expected response of a healthy term newborn?
A. The infant fannedly extends the legs and then draws them inward.
B. The infant turns the head toward the stimulus and sucks vigorously.
C. The infant abducts the arms and legs and then flexes them inward.
D. The infant flexes the toes upward when the sole of the foot is stroked.
Correct Answer: C
Rationale: This choice is correct because the Moro (startle) reflex involves a
symmetrical abduction and extension of the arms and legs followed by a flexion
(embrace) in response to a sudden movement or loud sound.
Q6: A mother brings her 12-month-old child to the clinic for a check-up. She is
concerned because the child says "mama" and "dada" but cannot form sentences. What
is the nurse’s best response?
A. "Your child is demonstrating a delay in language development; we should schedule a
hearing test immediately."
B. "This is normal development; at this age, one- or two-word phrases are expected, not
full sentences."
C. "You should encourage more television time to help the child learn vocabulary faster."
D. "Most 12-month-olds can speak in full sentences; we need to refer you to a speech
therapist."
Correct Answer: B
, Rationale: This aligns with developmental milestones because a 12-month-old typically
uses one or two words besides "mama" and "dada" and understands simple commands.
The ability to form sentences generally emerges between 18 and 24 months of age.
Q7: The nurse reviews the growth chart of a 2-year-old child. The child’s weight has
dropped from the 50th percentile to the 10th percentile over the last six months, while
height remains stable. This finding is most suggestive of:
A. Normal variation in growth patterns
B. Failure to thrive
C. Constitutional growth delay
D. Obesity
Correct Answer: B
Rationale: The best answer is failure to thrive because a significant drop in weight
percentile while maintaining length (linear growth) indicates inadequate weight gain or
weight loss, requiring further assessment for nutritional intake or underlying health
issues.
Q8: A 9-month-old infant becomes distressed and cries when a new babysitter enters
the room. The nurse recognizes this behavior as a sign of:
A. Separation anxiety
B. Stranger anxiety
C. Object permanence
D. Neglect
Correct Answer: B
Rationale: This choice is correct because stranger anxiety typically appears between 8
and 9 months of age when infants become more able to distinguish familiar faces from
strangers, leading to fear or distress in the presence of unknown individuals.
Q9: During a health supervision visit, the nurse provides anticipatory guidance to the
parents of a 6-month-old infant. Which recommendation regarding oral health is most
appropriate at this age?
A. Schedule the first dental visit by the first birthday.
B. Start fluoridated toothpaste twice daily.
C. Discontinue breastfeeding if the infant has started solids.
D. Offer fruit juice in a sippy cup to supplement fluid intake.
Correct Answer: A
Rationale: This aligns with current recommendations because the American Academy
of Pediatrics and AAPD advise establishing a dental home by age 1, which includes
scheduling the first dental visit. Fluoridated toothpaste (rice grain size) starts when teeth
erupt, and fruit juice is generally discouraged.
