The American Association of Critical-Care Nurses (AACN) CCRN-Pediatric exam is a certification exam for registered nurses who are seeking to validate their expertise in pediatric critical care nursing. CCRN-Pediatric exam assesses the nurses' ability to provide high-quality care to critically ill infants, children, and adolescents in various healthcare settings, including emergency departments, intensive care units, and specialty units.
AACN CCRN-Pediatric Certification Exam consists of 150 multiple-choice questions, and nurses have three hours to complete the exam. CCRN-Pediatric Exam covers a wide range of topics related to pediatric critical care nursing, including assessment and diagnosis, hemodynamics and cardiovascular concepts, neurologic and respiratory concepts, and professional caring and ethical practice.

AACN Critical Care Nursing Exam Sample Questions (Q16-Q21):
NEW QUESTION # 16
High-frequency ventilation improves pulmonary air leaks by:
- A. Increasing the pressure differential between the airway and the intrapleural space
- B. Increasing the mean airway pressure
- C. Decreasing the pressure differential between the airway and the intrapleural space
- D. Decreasing minute ventilation
Answer: C
Explanation:
High-frequency ventilation (HFV) utilizes very small tidal volumes delivered at rapid frequencies (often greater than 150 breaths per minute), which helps minimize alveolar overdistention and cyclical opening and closing of alveoli-both of which contribute to pulmonary air leak syndromes (e.g., pneumothorax, pulmonary interstitial emphysema).
According toCCRN (Pediatric) - Direct Care (Pulmonary Section):
"HFV is particularly beneficial in managing pulmonary air leaks by stabilizing alveoli with a constant mean airway pressure while using very low tidal volumes, which significantly reduce the pressure gradient between the airways and the surrounding intrapleural space. This promotes healing of alveolar disruptions and prevents further leakage." Therefore, thereduced pressure differentialprotects fragile alveoli and allows for tissue repair without additional mechanical trauma.
NEW QUESTION # 17
A 3 year-old child is being treated with Metronidazole suspension, 200 mg per dose. The child weighs 30 lbs. and the daily dose range is 20-40 mg/kg of body weight, in three divided doses every 8 hours.

- B. Hold the medicine as the dosage is way too low
- C. Recognize that the medicine were over-prescribed
- D. Administer the medicine as ordered
Answer: D
Explanation:
Explanation: The dose range is 20-40 mg/kg/day divided every 8 hours. 15kg x 40mg = 600mg, divided by
3 = 200 mg per dose. The prescribed dose is correct and should be given as ordered.
NEW QUESTION # 18
Why are unit admission and discharge criteria developed?
- A. Provide ethical decision-making guidelines
- B. Address triage decisions
- C. Secure managed care contracts
- D. Identify criteria for withholding treatment
Answer: A
Explanation:
Establishingadmission and discharge criteriaensures that care decisions areconsistent, justifiable, and ethically grounded. These criteria guide clinicians inresource allocation, promotingfair accessand minimizing bias in treatment decisions.
"Admission/discharge policies support ethical care delivery by ensuring objective, equitable decision-making, especially in high-acuity environments like ICUs." (Referenced from CCRN Pediatric - Professional Caring and Ethical Practice: Ethical Resource Management and Clinical Guidelines)
NEW QUESTION # 19
Michael, a toddler, was admitted at the hospital with a diagnosis of Wilm's tumor. The nurse should be aware that:
- A. disease is communicable therefore the client must be isolated.
- B. hypertension may occur at anytime of confinement.
- C. respiratory problems should be expected and reported.
- D. vigorous palpation of the mass must be avoided.
Answer: D
Explanation:
Explanation: The nurse should be aware that vigorous palpation of the mass must be avoided. The abdominal mass should be carefully examined. Palpating a mass too vigorously could lead to the rupture of a large tumor into the peritoneal cavity. There are hospitals that require nurses to put signs like" DO NOT PALPATE".
NEW QUESTION # 20
In a 3-year-old diagnosed with hemolytic uremic syndrome, which of the following findings requires immediate intervention?
- A. Weight gain of 2 kg in 24 hours
- B. ECG showing peaked, tented T waves
- C. ECG showing PR interval of 0.12 sec
- D. Positive guaiac test and 3+ protein in the urine
Answer: B
Explanation:
Peaked T waveson ECG are a hallmark ofhyperkalemia, which is a life-threatening electrolyte imbalance commonly seen inhemolytic uremic syndrome (HUS)due to acute kidney injury. This requiresimmediate interventionto prevent cardiac arrhythmias.
"In patients with HUS, hyperkalemia is a critical electrolyte disturbance. Peaked T waves are a warning sign of impending cardiac complications and demand emergent treatment." (Referenced from CCRN Pediatric - Direct Care: Renal, Hemolytic Uremic Syndrome and Electrolyte Emergencies)
