Introduction
This comprehensive examination is designed to rigorously assess the knowledge, critical thinking, and clinical
decision-making skills essential for the Certified Pediatric Emergency Nurse (CPEN). The assessment covers a broad
spectrum of pediatric emergencies, from foundational theory and pathophysiology to complex, real-world clinical
scenarios. Candidates will encounter a variety of multiple-choice questions that challenge their ability to prioritize
care, interpret assessment findings, and implement evidence-based interventions. Emphasis is placed on the
application of professional standards, ethical principles, and regulatory compliance in the dynamic and often high-
,acuity environment of pediatric emergency care. Successful completion of this exam indicates a readiness to
provide safe, competent, and compassionate care to pediatric patients and their families.
SECTION ONE: QUESTIONS 1–100
1. A 3-year-old child presents with a barking cough, inspiratory stridor at rest, and mild intercostal
retractions. The child is afebrile and has been experiencing these symptoms for the past two nights. What is
the priority intervention?
A. Obtain a lateral neck radiograph
B. Administer nebulized racemic epinephrine
C. Administer oral dexamethasone
D. Perform a nasopharyngeal suctioning
🟢 B. Administer nebulized racemic epinephrine
🔴 RATIONALE: The child's presentation is classic for moderate to severe croup (laryngotracheobronchitis). The
presence of stridor at rest indicates significant upper airway edema. Nebulized racemic epinephrine is the
priority intervention as it rapidly reduces airway edema through vasoconstriction, providing prompt relief of
respiratory distress. While dexamethasone is indicated for croup, its onset of action is slower, and racemic
epinephrine is the first-line treatment for acute, significant stridor.
,2. A 6-month-old infant is brought to the emergency department with fever, irritability, and a petechial rash
on the trunk and extremities. The infant is lethargic and has poor peripheral perfusion. Which of the
following is the priority intervention?
A. Administer intravenous acetaminophen
B. Obtain blood cultures and administer intravenous antibiotics
C. Administer a 20 mL/kg normal saline bolus
D. Administer intravenous corticosteroids
🟢 B. Obtain blood cultures and administer intravenous antibiotics
🔴 RATIONALE: The combination of fever, petechial rash, and lethargy in an ill-appearing infant is highly
concerning for meningococcemia or sepsis. This is a medical emergency. The priority is to obtain blood cultures
and then immediately administer broad-spectrum intravenous antibiotics (such as ceftriaxone or cefotaxime) to
cover Neisseria meningitidis. Delays in antibiotic administration can be fatal.
3. A 10-year-old child with a history of asthma is in severe respiratory distress. The child is using accessory
muscles, has a prolonged expiratory phase, and an SpO2 of 88% on room air. On auscultation, the chest is
silent. Which finding indicates impending respiratory failure?
A. Tachypnea
B. Use of accessory muscles
C. Wheezing throughout lung fields
D. Silent chest
, 🟢 D. Silent chest
🔴 RATIONALE: A silent chest on auscultation indicates minimal to no air movement, signifying severe
bronchospasm and airway obstruction. This is a critical sign of impending respiratory failure and requires
immediate, aggressive intervention. In contrast, wheezing indicates some degree of air movement, and while
tachypnea and accessory muscle use are signs of respiratory distress, they do not indicate the imminent failure
that a silent chest does.
4. A 4-year-old child presents with high fever, stridor, drooling, and is sitting upright in a tripod position.
What is the priority nursing action?
A. Perform a throat culture
B. Prepare for immediate airway management
C. Administer oral fluids
D. Place the child in a supine position for examination
🟢 B. Prepare for immediate airway management
🔴 RATIONALE: This presentation is classic for epiglottitis, a life-threatening emergency characterized by rapid-
onset airway obstruction. The tripod position and drooling are signs of severe respiratory distress. The priority
action is to prepare for immediate airway management (e.g., intubation or tracheostomy) as any stimulation,
including examination or throat culture, can precipitate complete airway occlusion. The child should be kept
calm and in a position of comfort.
