CPEN Exam 4

Question 1

A 5-year-old is found unresponsive. The nurse confirms no pulse and begins CPR. What is the correct compression-to-ventilation ratio for a single rescuer?

Accepted Answer

30:2

Answer

A single rescuer performing CPR on a child uses a 30:2 compression-to-ventilation ratio, consistent with adult BLS guidelines.

Question 2

A 14-year-old athlete collapses during practice and has no pulse. The AED identifies a shockable rhythm. What is the correct initial energy dose for a pediatric defibrillation?

Accepted Answer

2 J/kg

Answer

The initial pediatric defibrillation dose is 2 J/kg, with subsequent shocks at 4 J/kg if the initial shock is unsuccessful.

Question 3

A 3-year-old presents with stridor at rest, a barking cough, and mild retractions. The nurse assigns a croup score of 3. Which initial treatment is most appropriate?

Accepted Answer

Oral dexamethasone only

Answer

Mild to moderate croup (scores 1-5) is managed with a single oral dose of dexamethasone, which reduces airway inflammation.

Question 4

A nurse is caring for a child with a suspected spinal injury after a diving accident. Which cervical immobilization device is most appropriate for initial prehospital stabilization?

Accepted Answer

Rigid cervical collar and backboard

Answer

A rigid cervical collar combined with spinal backboard immobilization provides the best initial stabilization for suspected cervical spine injury in the prehospital setting.

Question 5

A 6-year-old with known peanut allergy develops urticaria, throat tightness, and hypotension after eating at a restaurant. What is the FIRST priority intervention?

Accepted Answer

Administer intramuscular epinephrine (0.01 mg/kg)

Answer

Epinephrine IM is the first and most critical intervention in anaphylaxis, as it reverses bronchospasm, vasodilation, and urticaria.
