AACN CCRN Pediatric Certification Examination Practice Test
Pediatric critical care nursing requires interpreting changes in a child’s physiology and responding to life-threatening instability. Practice-bank scenarios include congenital cardiac shunts, tamponade, respiratory failure, burns, chemotherapy-associated neutropenia, vascular catheter complications, spinal cord injury, pancreatitis, and acute anemia. They connect assessment findings with immediate priorities in intensive care.
Exam overview
About the AACN CCRN Pediatric Certification Examination Exam
Questions call for linking bedside signs to mechanisms such as pulmonary overcirculation from a ventricular septal defect, impaired cardiac filling from pericardial tamponade, and respiratory acidosis from hypoventilation. Other scenarios test recognition of poor tissue perfusion, fluid-resuscitation response, compromised distal circulation after arterial catheterization, and fever with severe neutropenia. Nursing decisions include protecting a threatened airway, escalating care for hemodynamic deterioration, assessing renal perfusion through urine output trends, and tracking oxygen delivery in anemia. Work through each case by identifying the most urgent threat, distinguishing expected findings from deterioration, and selecting an action that supports stabilization while avoiding delays in definitive treatment. These cases also reinforce age-specific assessment, hemodynamic interpretation, and prioritization when several findings change at once.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A child with a large ventricular septal defect has tachypnea, hepatomegaly, and poor weight gain. Which physiological problem most directly accounts for these findings?
Show answer
Correct answer: AA significant ventricular septal defect can permit left-to-right shunting, increasing pulmonary blood flow and cardiac workload. Pulmonary congestion and heart failure may present with tachypnea, hepatomegaly, and feeding difficulty or poor growth.
A child with a new pericardial effusion becomes tachycardic and hypotensive. Heart sounds are difficult to hear, and the pulse pressure is narrowing. Which complication should the nurse suspect?
Show answer
Correct answer: AA pericardial effusion can impair cardiac filling and cause tamponade. Tachycardia, hypotension, and muffled heart sounds are concerning findings; urgent evaluation and preparation for pericardial drainage may be necessary.
A child with a large burn has decreasing urine output despite prescribed fluid resuscitation. Which interpretation is most appropriate?
Show answer
Correct answer: AUrine output is commonly monitored as a perfusion endpoint during burn resuscitation. A decline calls for prompt reassessment of hemodynamics, fluid delivery, catheter patency, and other potential causes; it does not by itself establish kidney failure.
A child with a newly inserted femoral arterial catheter has a cool, pale foot on the catheterized side and weaker distal pulses than the opposite foot. What is the best nursing response?
Show answer
Correct answer: BA cool, pale extremity with diminished pulses may indicate arterial obstruction or compromised perfusion. Prompt assessment and escalation are needed to protect the limb and guide intervention.
A child receiving chemotherapy has a temperature of 38.5°C (101.3°F) and a markedly low absolute neutrophil count. What is the priority response?
Show answer
Correct answer: AFever with severe neutropenia can indicate rapidly progressive infection. It requires timely clinical evaluation and management according to the facility's pathway; rectal procedures are generally avoided in neutropenic patients because of mucosal injury and infection risk.
A child with acute respiratory distress has inspiratory stridor, suprasternal retractions, and a hoarse voice. Which action is most appropriate while preparing for definitive airway management?
Show answer
Correct answer: AWith signs of upper-airway obstruction, agitation and unnecessary airway manipulation can precipitate worsening obstruction. Keep the child calm, provide oxygen as tolerated, and promptly involve clinicians prepared to secure the airway. Pharyngeal inspection, supine positioning, and oral intake may increase risk or delay care.
A child with a high cervical spinal cord injury develops sudden severe hypertension, flushing above the injury, and a pounding headache. What should the nurse do first?
Show answer
Correct answer: BThese findings suggest autonomic dysreflexia. Sitting the child upright can help lower blood pressure; promptly identify and remove triggers, commonly bladder or bowel distention, while monitoring closely and following the treatment plan.
How to use this practice test
Access is free. The practice page draws up to 20 random questions from its 50-question bank for each session and shows results afterward. Use missed or uncertain items to identify clinical patterns to revisit, such as respiratory compensation, perfusion changes, and emergency responses to pediatric instability.
Preparation tips
- For cardiac cases, connect shunt direction and volume overload with findings such as tachypnea, hepatomegaly, and poor growth; distinguish these from signs of tamponade and reduced cardiac output.
- Practice interpreting arterial blood gases by relating pH and PaCO₂ to respiratory acidosis, then connect the result to ventilation and the child’s clinical status.
- Review pediatric burn resuscitation trends, including urine output, and consider whether findings indicate inadequate renal perfusion or a need for prompt reassessment.
- For fever during chemotherapy, pair temperature with absolute neutrophil count and prioritize urgent evaluation for infection in a neutropenic child.
- Rehearse immediate responses to stridor and to acute limb ischemia after femoral arterial catheterization, focusing on airway protection and rapid escalation of impaired perfusion.
