COMPREHENSIVE PEDIATRIC NURSING CERTIFICATION
EXAMINATION
Focus: Growth, Development, Infant Milestones, and Developmental
Delay Evaluation (200 Questions with Rationales)
SECTION 1: INFANT DEVELOPMENT & 9-MONTH
EVALUATION (Questions 1 - 50)
Question 1: A nurse is assessing a 9-month-old infant during a well-
child visit. Which of the following findings indicates a
developmental delay that requires further evaluation?
A. Inability to pull to a standing position
B. Inability to transfer objects from one hand to the other
C. Absence of babbling with consonant sounds ('ba-ba', 'da-da')
D. Inability to walk independently
Correct Answer: D. Inability to walk independently
Rationale: Independent walking is typically achieved around 12 to 15
months of age. Expecting a 9-month-old to walk independently is
developmentally inappropriate. At 9 months, expected milestones
include sitting without support (tripod sitting or steady sitting),
pulling to stand (by 9-10 months), transferring objects between
hands, and babbling with consonants.

developmentally inappropriate. At 9 months, expected milestones
include sitting without support, pulling to stand, transferring objects,
and babbling.
Question 2: During a routine well-child evaluation, a nurse assesses
the language and communication of a 7-month-old infant. Which
finding represents a normal developmental milestone for this age
group?
A. Cooing and vocalizing vowel sounds
B. Using single words with intent ('mama', 'dada')
C. Combining 3-to-4 word sentences
D. Engaging in abstract political debate
Correct Answer: C. Combining 3-to-4 word sentences
Rationale: At this developmental stage (7-month-old infant),
assessing language and communication requires understanding
standardized pediatric milestones. Expected findings align with
normative data from the AAP and standardized screening tools such
as the Denver II and ASQ, ensuring early identification of deviations.
Question 3: During a routine well-child evaluation, a nurse assesses
the social-emotional of a 10-month-old infant. Which finding
represents a normal developmental milestone for this age group?
A. Responding with a social smile
B. Experiencing peak stranger and separation anxiety
C. Developing peer-oriented cooperative play
D. Forming complex romantic attachments
, Correct Answer: B. Experiencing peak stranger and separation
anxiety
Rationale: At this developmental stage (10-month-old infant),
assessing social-emotional requires understanding standardized
pediatric milestones. Expected findings align with normative data
from the AAP and standardized screening tools such as the Denver II
and ASQ, ensuring early identification of deviations.
Question 4: During a routine well-child evaluation, a nurse assesses
the cognitive development of a 13 month-old toddler. Which finding
represents a normal developmental milestone for this age group?
A. Demonstrating basic object permanence
B. Understanding abstract hypothetical reasoning
C. Exhibiting magical thinking characteristic of preoperational stage
D. Achieving formal operational logic
Correct Answer: B. Understanding abstract hypothetical reasoning
Rationale: At this developmental stage (13 month-old toddler),
assessing cognitive development requires understanding standardized
pediatric milestones. Expected findings align with normative data
from the AAP and standardized screening tools such as the Denver II
and ASQ, ensuring early identification of deviations.
Question 5: During a routine well-child evaluation, a nurse assesses
the gross motor of a 16 month-old toddler. Which finding represents
a normal developmental milestone for this age group?
A. Demonstrating steady head control without lag
B. Walking independently with a steady gait
C. Hopping on one foot consecutively
D. Skipping and jumping rope
, Correct Answer: C. Hopping on one foot consecutively
Rationale: At this developmental stage (16 month-old toddler),
assessing gross motor requires understanding standardized pediatric
milestones. Expected findings align with normative data from the
AAP and standardized screening tools such as the Denver II and
ASQ, ensuring early identification of deviations.
Question 6: During a routine well-child evaluation, a nurse assesses
the fine motor of a 19 month-old toddler. Which finding represents
a normal developmental milestone for this age group?
A. Palmar grasp reflex present
B. Transferring objects between hands
C. Building a tower of six blocks
D. Writing first and last name legibly
Correct Answer: C. Building a tower of six blocks
Rationale: At this developmental stage (19 month-old toddler),
assessing fine motor requires understanding standardized pediatric
milestones. Expected findings align with normative data from the
AAP and standardized screening tools such as the Denver II and
ASQ, ensuring early identification of deviations.
Question 7: During a routine well-child evaluation, a nurse assesses
the language and communication of a 22 month-old toddler. Which
finding represents a normal developmental milestone for this age
group?
A. Cooing and vocalizing vowel sounds
B. Using single words with intent ('mama', 'dada')
C. Combining 3-to-4 word sentences
D. Engaging in abstract political debate
