CPN Injury Prevention Practice Questions (10 Flashcards)

The maximum recommended temperature is 120°F (49°C). At 140°F, a deep partial-thickness burn can occur in just 3 seconds, whereas at 120°F, it takes nearly 5 minutes of exposure. Exam Strategy: PNCB frequently tests this specific number. Distractors often include 110°F (too low for sanitation) or 130°F (too high for safety). Nurses should also educate that bath water should be tested with the wrist or elbow and should ideally be around 100°F.

Parents must secure heavy furniture (dressers, TVs) to the wall using anchors. As infants pull themselves up, they are at high risk for tip-over injuries. Exam Strategy: PNCB questions link developmental milestones to specific risks. For a 10-month-old, the priority is furniture anchors and stair gates. For a 4-month-old, the priority is not leaving them unattended on high surfaces (rolling). Avoid wheeled baby walkers as a recommendation; they are a major fall hazard and discouraged by the AAP.

The priority is monitoring for delayed respiratory compromise (formerly called secondary drowning). Submersion can lead to surfactant washout, pulmonary edema, and inflammatory lung injury that may not manifest immediately. Exam Strategy: Patients who are symptomatic (tachypnea, cough, hypoxia) require observation and likely admission. If a child is completely asymptomatic with normal vitals for 6-8 hours, they may be discharged. PNCB focuses on the fact that asymptomatic doesn't mean safe to leave immediately.

1. Cardiac Arrhythmias: Electrical current can disrupt the heart's conduction (monitor via EKG/telemetry). 2. Myoglobinuria/Rhabdomyolysis: Internal tissue damage releases myoglobin, which can cause Acute Kidney Injury (AKI). Exam Strategy: Electrical burns are often iceberg injuries where surface damage is minimal but internal damage is severe. PNCB expects nurses to prioritize cardiac monitoring and IV fluid resuscitation to maintain high urine output (clearance of pigments) in these cases.

The nurse should strongly discourage wheeled walkers. They do not help children learn to walk and are a leading cause of head injuries and ED visits due to falling down stairs or reaching hot surfaces/poisons faster than expected. Exam Strategy: The AAP has called for a ban on wheeled walkers. The CPN exam looks for the nurse to suggest safer alternatives like stationary activity centers (Exersaucers) or supervised floor time. Distractors will suggest walkers are safe if supervised, but the correct answer is complete avoidance.
