INTRODUCTION
This comprehensive assessment is designed to prepare candidates for the Certified
Pediatric Nurse (CPN) examination. The primary purpose of this exam is to validate
the clinical expertise, diagnostic reasoning, and specialized knowledge required to
provide high-quality nursing care to the pediatric population. The assessment covers
a wide spectrum of topics including physiological needs, developmental milestones,
,and complex multi-system disorders. Utilizing a mix of foundational theory and
scenario-based questions, the exam emphasizes real-world application, critical
thinking, and ethical decision-making. Each question is structured to reflect the
challenges faced by pediatric nurses in diverse clinical settings, ensuring a robust
evaluation of professional competency.
SECTION ONE: QUESTIONS 1–100
1. A 4-year-old child is admitted with suspected epiglottitis. Which of the following
nursing interventions is the highest priority?
A. Obtain a throat culture to identify the pathogen
B. Initiate a peripheral IV for fluid resuscitation
🟢 C. Ensure emergency airway equipment is available at the bedside
D. Position the child supine to facilitate breathing
🔴 RATIONALE: Epiglottitis is a medical emergency that can lead to sudden airway
obstruction. Examination of the throat or stressful interventions can trigger
laryngospasm; therefore, maintaining a patent airway and having intubation or
tracheostomy equipment ready is the priority.
, 2. According to Piaget’s stages of cognitive development, a 9-year-old child should
be in which stage?
A. Sensorimotor
B. Preoperational
🟢 C. Concrete operational
D. Formal operational
🔴 RATIONALE: Children aged 7 to 11 years are in the concrete operational stage,
where they begin to think logically about concrete events and understand the concept
of conservation.
3. A nurse is preparing to administer an intramuscular (IM) injection to a 10-month-
old infant. Which site is most appropriate?
🟢 A. Vastus lateralis
B. Dorsogluteal
C. Deltoid
D. Ventrogluteal
🔴 RATIONALE: The vastus lateralis is the preferred site for IM injections in infants
because it is the most developed muscle mass in this age group and avoids proximity
, to major nerves and vessels.
4. Which clinical manifestation is most characteristic of a child with pyloric
stenosis?
A. Currant jelly stools
🟢 B. Projectile vomiting after feedings
C. Ribbon-like stools
D. Right lower quadrant pain
🔴 RATIONALE: Hypertrophic pyloric stenosis typically presents with non-bile-
stained projectile vomiting shortly after feeding, often accompanied by an olive-
shaped mass in the epigastrium.
5. A 6-year-old with sickle cell anemia is admitted for a vaso-occlusive crisis. What
is the primary goal of nursing care?
A. Administering prophylactic antibiotics
🟢 B. Managing pain and maintaining hydration
C. Encouraging vigorous physical activity
D. Monitoring for signs of iron deficiency
