INTRODUCTION
The Certified Pediatric Nurse (CPN) credential is awarded by the Pediatric Nursing
Certification Board (PNCB) to registered nurses who demonstrate specialized knowledge and
competence in pediatric nursing. The CPN role encompasses health promotion, acute and chronic
illness management, health restoration, family-centered care, and professional practice for
infants, children, and adolescents.
Eligibility is based on PNCB requirements for pediatric nursing experience and an active,
unrestricted RN license. Current PNCB information describes pathways involving recent
pediatric clinical practice or an alternative pathway based on longer pediatric nursing experience.
Candidates should verify the requirements applicable to their individual application directly with
PNCB.
CPN certification provides formal recognition of pediatric nursing expertise and can support
professional development, career advancement, and demonstration of specialized pediatric
nursing competence. CPNs practice in diverse settings including children's hospitals, community
hospitals, schools, home health, specialty clinics, public health agencies, and primary care
practices.
The current CPN examination consists of 175 multiple-choice questions with 3 hours (180
minutes) of testing time. The exam tests application and critical-thinking skills rather than
simple memorization. PNCB identifies four major content areas: Health Promotion, Assessment,
Planning and Management, and Professional Responsibilities.

The percentages and item counts above reflect PNCB's current published CPN blueprint. The
actual examination contains 175 questions; this practice set intentionally contains 200 original
questions for expanded study coverage.
QUESTIONS 1–200
Q1: A 2-month-old infant is brought for a routine visit. The parents report that the infant
briefly lifts the head when prone and follows a face with the eyes. Which nursing response
is most appropriate?
A) These findings indicate a significant gross-motor delay.
B) These behaviors are consistent with expected early developmental progression.
C) The infant should already be sitting independently.
D) The infant should be referred immediately for neurological imaging.
Correct Answer: B
Rationale: At approximately 2 months, emerging head control and visual tracking are expected
developmental behaviors. Independent sitting is not expected at this age. The findings do not by
themselves indicate neurological pathology or justify imaging. Development should be evaluated
longitudinally and in the context of the complete developmental assessment.
Q2: A 15-month-old has a weight below the fifth percentile but has followed approximately
the same growth curve since infancy. The child is active and developmentally appropriate.
What should the nurse do first?
A) Recommend immediate high-calorie supplementation.
B) Evaluate the child's growth pattern, dietary intake, and parental heights.
C) Diagnose failure to thrive.
D) Restrict physical activity.
Correct Answer: B
Rationale: A low percentile is not necessarily abnormal when the child follows an established
trajectory and has otherwise normal development. Assessment should include growth history,
,nutritional intake, feeding behavior, and genetic potential. Failure to thrive requires evidence of
inadequate growth or nutritional compromise rather than a single low percentile.
Q3: A 4-year-old becomes frightened during an abdominal examination. Which
intervention best supports developmentally appropriate care?
A) Complete the examination rapidly without explanation.
B) Ask the child to remain completely still.
C) Allow the child to handle safe equipment and explain each step in simple terms.
D) Separate the child from the parent during the examination.
Correct Answer: C
Rationale: Preschool children benefit from simple explanations, play, choices, and opportunities
to interact with equipment. Parent presence can provide reassurance. Completing the
examination without explanation may increase fear, while unnecessary separation removes an
important source of security.
Q4: A school-age child with asthma says, “I only use my controller inhaler when I feel
wheezy.” Which teaching point is most important?
A) Stop the medication whenever symptoms disappear.
B) Controller therapy is intended for regular use even when the child feels well.
C) Use the controller only before exercise.
D) Replace the controller with the rescue inhaler.
Correct Answer: B
Rationale: Controller medications are used regularly to reduce airway inflammation and
prevent exacerbations. They are not intended solely for immediate symptom relief. Rescue
medication treats acute bronchoconstriction, whereas controller therapy addresses the
underlying inflammatory process.
Q5: A 6-month-old has fewer wet diapers, dry mucous membranes, and a sunken anterior
fontanelle after several days of diarrhea. Which finding most strongly indicates significant
dehydration?
A) Mild irritability
B) Slightly decreased appetite
C) Reduced urine output with signs of poor perfusion
D) One episode of loose stool
Correct Answer: C
Rationale: Decreased urine output is an important indicator of reduced renal perfusion and
significant fluid loss. Dry mucous membranes and a sunken fontanelle further support
dehydration. Irritability and decreased appetite are less specific and can occur with many
pediatric illnesses.
Q6: A 3-year-old with gastroenteritis is lethargic, tachycardic, and has delayed capillary
refill. Which action has priority?
A) Offer a large meal.
B) Obtain a stool culture before any intervention.
C) Initiate rapid assessment and treatment of circulatory compromise.
D) Encourage unrestricted oral juice intake.
, Correct Answer: C
Rationale: Lethargy, tachycardia, and delayed capillary refill indicate potentially significant
hypovolemia and impaired perfusion. Stabilization takes priority over diagnostic testing or oral
nutrition. Large amounts of hypotonic or sugary beverages can worsen gastrointestinal
symptoms and do not provide appropriate resuscitation.
Q7: A 7-year-old with sickle cell disease reports severe extremity pain. Which intervention
should the nurse anticipate?
A) Restrict fluids.
B) Encourage strenuous exercise.
C) Provide prescribed analgesia and maintain adequate hydration.
D) Apply prolonged cold therapy to painful areas.
Correct Answer: C
Rationale: Vaso-occlusive pain episodes require prompt analgesia, hydration as clinically
appropriate, oxygen if hypoxemia is present, and treatment of precipitating factors. Dehydration
can worsen sickling. Cold exposure and strenuous activity can increase vasoconstriction or
metabolic demand.
Q8: A child receiving chemotherapy develops a temperature of 38.5°C (101.3°F). The child
has an absolute neutrophil count of 400/mm³. What is the priority?
A) Administer acetaminophen and reassess tomorrow.
B) Treat the fever as a potential neutropenic emergency and initiate the prescribed
evaluation pathway.
C) Place the child in a crowded waiting area for observation.
D) Delay cultures until the next scheduled chemotherapy visit.
Correct Answer: B
Rationale: Fever in a profoundly neutropenic child can indicate life-threatening infection with
minimal localizing signs. Prompt cultures, assessment, and empiric antimicrobial therapy
according to institutional protocol are critical. Antipyretics do not address the underlying
infection and should not delay evaluation.
Q9: A 10-year-old receiving insulin becomes pale, sweaty, confused, and shaky. What
should the nurse do first if the child is awake and able to swallow?
A) Administer the next scheduled insulin dose.
B) Give a rapid-acting source of glucose.
C) Encourage vigorous exercise.
D) Restrict oral intake.
Correct Answer: B
Rationale: Diaphoresis, tremor, confusion, and pallor are classic manifestations of
hypoglycemia. If the child is conscious and able to swallow safely, rapid-acting carbohydrate
should be administered and glucose reassessed. Exercise and additional insulin can worsen
hypoglycemia.
Q10: A 5-year-old with type 1 diabetes has vomiting, abdominal pain, deep respirations,
and a fruity odor to the breath. Which condition should the nurse suspect?
A) Hypoglycemia
