Introduction
This comprehensive examination is designed to assess the advanced clinical knowledge, diagnostic reasoning, and
critical decision-making skills required for the Pediatric Acute Care Nurse Practitioner (PNP-AC) certification. The
exam covers foundational theory, applied professional knowledge, regulatory and legal compliance, ethics, and
real-world clinical scenarios. Each question is structured as a multiple-choice item with a single best answer,
accompanied by a detailed rationale to reinforce learning. Emphasis is placed on the ability to synthesize complex
patient data, prioritize interventions, and deliver evidence-based, family-centered care across acute, critical, and
,chronic pediatric populations. This assessment mirrors the rigor and format of the national certification
examination.
SECTION ONE: QUESTIONS 1–100
Question 1
A 6-month-old infant is brought to the emergency department with a 2-day history of fever, poor feeding, and
a bulging anterior fontanelle. The infant is irritable and difficult to console. Which of the following is the most
appropriate next step in management?
A. Administer intravenous ceftriaxone and vancomycin after blood and cerebrospinal fluid cultures
B. Obtain a complete blood count and blood culture only
C. Perform a lumbar puncture prior to antibiotic administration
D. Start oral antibiotics and observe for 24 hours
🟢C
🔴 RATIONALE: In an infant with suspected meningitis, the priority is to obtain cerebrospinal fluid (CSF) for
culture and analysis before initiating antibiotics to maximize diagnostic yield. While blood cultures should also
,be obtained, delaying lumbar puncture until after antibiotics can compromise CSF culture results and obscure
the diagnosis.
Question 2
A 3-year-old child with a history of sickle cell disease presents with fever of 38.9°C, cough, and chest pain. The
parent reports the child has been less active than usual. Which of the following is the priority diagnostic study?
A. Chest X-ray
B. Complete blood count with differential
C. Blood culture
D. Rapid viral respiratory panel
🟢A
🔴 RATIONALE: Children with sickle cell disease and fever are at high risk for acute chest syndrome, a leading
cause of mortality. A chest X-ray is the priority to evaluate for infiltrates or effusions, which are hallmark
findings. While blood cultures and CBC are important, the chest X-ray provides immediate information to guide
urgent management.
, Question 3
A 10-year-old child is brought to the emergency department after a motor vehicle accident. The child is alert
but complains of severe abdominal pain. The primary survey reveals a heart rate of 140 beats per minute, blood
pressure 90/60 mmHg, and respiratory rate 24 breaths per minute. Which of the following is the most
appropriate initial intervention?
A. Place the child in the Trendelenburg position
B. Administer a 20 mL/kg bolus of isotonic crystalloid
C. Obtain a CT scan of the abdomen and pelvis
D. Insert a nasogastric tube
🟢B
🔴 RATIONALE: The child is showing signs of compensated shock with tachycardia and hypotension. The
priority is fluid resuscitation with an isotonic crystalloid bolus of 20 mL/kg. This should be done before
diagnostic imaging to stabilize hemodynamics and prevent progression to decompensated shock.
Question 4
A 2-week-old neonate presents with poor feeding, lethargy, and a temperature of 37.8°C. The infant was born at
38 weeks gestation via uncomplicated vaginal delivery. Which of the following is the most likely diagnosis?
