Introduction
This comprehensive examination is designed for candidates preparing for the
Certified Pediatric Nurse (CPN) credential. It assesses the essential knowledge,
critical thinking skills, and clinical judgment required for excellence in pediatric
nursing practice. The exam covers key domains, including health promotion, disease
management, pharmacology, and family-centered care, all presented through a
rigorous format. It features a blend of foundational theory questions and complex,
real-world scenario-based items that require the application of evidence-based
practice. The emphasis is on safe, ethical, and effective decision-making to ensure
readiness for professional certification and clinical leadership.
,Section One: Questions 1 – 50
1. A nurse is assessing a 2-year-old child in the clinic. Which developmental
milestone is the nurse most likely to observe?
A. The child is able to tie their shoelaces.
B. The child can draw a circle.
C. The child speaks in three- to four-word sentences.
D. The child can walk up and down stairs independently.
🟢 Correct Answer: C. The child speaks in three- to four-word sentences.
🔴 Explanation: By age 2, a child typically uses simple phrases and short
sentences of three to four words. Tying shoelaces is a skill for school-aged
children. Drawing a circle is usually achieved by age 3. Walking up and down
stairs independently is a milestone for a 2.5- to 3-year-old, but often requires
support on the rail.
2. The mother of a 4-month-old infant reports that the baby is not sleeping
through the night. What is the most appropriate nursing response?
A. "You should start weaning the infant to solid foods at bedtime."
B. "This is normal for a 4-month-old. You can start gentle sleep training by
establishing a consistent bedtime routine."
C. "This is a concern for failure to thrive; you should increase the volume of
daytime feedings."
D. "You should put the infant in bed with you to help them feel more secure."
🟢 Correct Answer: B. "This is normal for a 4-month-old. You can start gentle
sleep training by establishing a consistent bedtime routine."
🔴 Explanation: At 4 months, many infants have not yet developed a mature
sleep-wake cycle. Establishing a consistent, calming bedtime routine is an
appropriate and safe first step. Solid foods are not introduced at 4 months (and
,are not a sleep solution). Co-sleeping is not recommended due to SIDS risk. This
is not a sign of failure to thrive without other indicators.
3. A nurse is preparing to administer a vaccine to a 6-month-old infant. The
infant's mother expresses hesitancy, stating she has read about side effects
online. Which action by the nurse is most appropriate?
A. Respectfully listen to the mother's concerns and provide evidence-based
information about the vaccine's safety and efficacy.
B. Tell the mother that she must have the vaccine to protect her child from
disease.
C. Skip the vaccine today and tell her to reschedule when she is more
comfortable.
D. Ask the mother if she has researched the topic from reputable sources.
🟢 Correct Answer: A. Respectfully listen to the mother's concerns and provide
evidence-based information about the vaccine's safety and efficacy.
🔴 Explanation: This demonstrates family-centered care, active listening, and
patient education. Addressing concerns with factual information is the most
therapeutic and ethical approach. Dismissing the mother's concerns (B) or
postponing without education (C) is not optimal. Asking about her research
sources (D) could be perceived as dismissive and is not the most immediate or
effective intervention.
4. A 9-year-old child with type 1 diabetes mellitus is brought to the emergency
department with a blood glucose level of 350 mg/dL. The child has been
vomiting for the past four hours. Which finding would the nurse expect to
observe?
A. Tremors and confusion
B. Deep, rapid respirations
, C. Decreased heart rate
D. Flushed, dry skin
🟢 Correct Answer: B. Deep, rapid respirations
🔴 Explanation: Hyperglycemia with vomiting suggests possible diabetic
ketoacidosis (DKA). The body attempts to blow off excess CO2 through Kussmaul
respirations (deep, rapid breathing) to compensate for metabolic acidosis.
Tremors and confusion are signs of hypoglycemia. Tachycardia, not bradycardia, is
seen in DKA. While dry skin can occur, it is not the pathognomonic sign; Kussmaul
respirations are a hallmark of DKA.
5. The nurse is assessing the pain of a 3-year-old child postoperatively. Which
pain scale is the most appropriate for this age group?
A. Numeric Rating Scale (0-10)
B. Visual Analog Scale
C. FLACC Scale
D. Wong-Baker FACES Pain Rating Scale
🟢 Correct Answer: C. FLACC Scale
🔴 Explanation: The FLACC Scale (Face, Legs, Activity, Cry, Consolability) is a
behavioral pain assessment scale designed for children ages 2 months to 7 years
who cannot reliably self-report pain. Numeric and Visual Analog scales require
cognitive abilities usually developed in older children (over age 7). The Wong-
Baker FACES scale is suitable for children 3 years and older, but the FLACC scale is
considered more appropriate and reliable for a 3-year-old postoperatively,
especially when they may be sleepy or unable to communicate effectively.
6. A nurse is providing anticipatory guidance to the parents of a 12-month-old.
The nurse should instruct the parents to ensure that their child's diet includes
