Introduction:
This comprehensive examination is designed to rigorously assess the knowledge and clinical decision-making skills
essential for the Certified Pediatric Emergency Nurse (CPEN). The assessment covers a wide array of critical
domains, from foundational pathophysiology to complex, real-world scenarios encountered in the emergency
department. Candidates will navigate multiple-choice questions and clinical vignettes that challenge their ability
,to synthesize information, prioritize care, and apply evidence-based interventions. The emphasis is on practical
application, safety, and the nuanced management of pediatric patients from infancy through adolescence,
ensuring the test-taker is prepared for the demands of a high-acuity emergency environment.
Section One: Questions 1-100
1. The nurse is triaging a 4-year-old child who presents with a barking cough, stridor, and a temperature of
38.5°C (101.3°F). The child is sitting upright and drooling. Which intervention should the nurse prioritize?
A. Prepare for immediate intubation.
B. Obtain a throat culture.
C. Administer racemic epinephrine via nebulizer.
D. Allow the child to remain in a position of comfort.
🟢 D. Allow the child to remain in a position of comfort.
🔴 RATIONALE: The child's presentation (barking cough, stridor, drooling, sitting upright) is highly suggestive of
epiglottitis, a life-threatening airway emergency. The priority is to minimize agitation and maintain airway
patency. Allowing the child to remain in a position of comfort is critical, as any intervention that causes distress,
including an examination, can precipitate complete airway obstruction. Immediate intubation may be necessary
but is not the first intervention unless the child shows signs of impending respiratory failure.
2. What is the most reliable indicator of adequate hydration status in a 6-month-old infant?
A. Skin turgor
B. Urine output
,C. Tears
D. Weight change
🟢 D. Weight change
🔴 RATIONALE: Changes in body weight are the most sensitive and reliable indicator of fluid balance in infants
and children. A loss of 1 gram is approximately equivalent to 1 mL of fluid loss. While urine output, skin turgor,
and tears are valuable clinical signs, they are more subjective and can be influenced by other factors.
3. A 14-year-old is brought to the ED after a motor vehicle accident. The patient is alert and oriented but
complains of severe abdominal pain. The nurse notes seatbelt marks across the chest and abdomen. Which
finding should cause the greatest concern for an intra-abdominal injury?
A. Mild tachycardia
B. Bruising in the flank area
C. Complaints of nausea
D. Complaints of left shoulder pain
🟢 D. Complaints of left shoulder pain
🔴 RATIONALE: Left shoulder pain (Kehr's sign) in a patient with abdominal trauma is a classic indicator of
diaphragmatic irritation, often due to splenic rupture and subsequent intra-abdominal bleeding. While
tachycardia, nausea, and flank bruising (which could indicate retroperitoneal injury) are concerning, Kehr's sign
is a more specific indicator of splenic injury requiring immediate surgical consultation.
4. The emergency nurse is caring for a 2-year-old child with febrile seizures. The seizure has stopped, and the
child is now postictal. The parent asks what caused the seizure. What is the nurse's best response?
A. "Your child may have a severe underlying neurological disorder."
B. "A rapid rise in temperature can trigger a seizure in some children."
, C. "The seizure was likely caused by an electrolyte imbalance."
D. "This means your child will likely develop epilepsy later in life."
🟢 B. "A rapid rise in temperature can trigger a seizure in some children."
🔴 RATIONALE: Simple febrile seizures are common in children ages 6 months to 5 years and are often
triggered by a rapid increase in core body temperature. They are typically benign and do not necessarily
indicate a neurological disorder or that the child will develop epilepsy. The nurse's response should be accurate,
reassuring, and avoid providing false or alarming information.
5. A 10-year-old with asthma is receiving a continuous albuterol nebulizer treatment. The nurse assesses the
patient and notes a heart rate of 150 bpm, tremors, and reports of nausea. Which action is most appropriate?
A. Continue the treatment as ordered; these are expected side effects.
B. Stop the treatment immediately and prepare for intubation.
C. Stop the treatment and notify the provider of the patient's symptoms.
D. Increase the flow rate of the oxygen to deliver the medication faster.
🟢 C. Stop the treatment and notify the provider of the patient's symptoms.
🔴 RATIONALE: Tachycardia, tremors, and nausea are signs of beta-2 agonist toxicity (e.g., from albuterol).
While these are side effects, they are not merely expected; they indicate a need for clinical evaluation. The nurse
should hold the treatment and inform the provider to reassess the patient's respiratory status and medication
regimen, as the side effects may limit further treatment.
6. The nurse is assessing a 3-month-old infant with a fever and is unable to visualize the tympanic
membrane due to cerumen. What is the most appropriate action?
A. Use a tympanometric device to assess for middle ear fluid.
B. Document the assessment as "unable to visualize."
