PALS - Pediatric Advanced Life Support High-Quality Pediatric BLS Questions and Answers

Question 1

When performing two-rescuer CPR on a 4-year-old child, what is the correct chest compression-to-ventilation ratio?

Accepted Answer

15:2

Answer

30:2

Answer

15:1

Answer

30:1

Question 2

You are performing high-quality CPR on a 7-year-old child. What is the recommended depth for chest compressions?

Accepted Answer

At least one-third the anterior-posterior diameter of the chest, approximately 2 inches (5 cm).

Answer

At least one-fourth the anterior-posterior diameter of the chest, approximately 1.5 inches (4 cm).

Answer

At least one-half the anterior-posterior diameter of the chest.

Answer

A depth of 2.5 inches (6.5 cm) to maximize cardiac output.

Question 3

Which of the following is the primary physiological reason for allowing the chest to fully recoil between each compression?

Accepted Answer

To allow the heart to adequately fill with blood before the next compression.

Answer

To prevent rescuer fatigue and maintain a consistent rate.

Answer

To reduce the risk of iatrogenic injuries such as rib fractures.

Answer

To create positive intrathoracic pressure, which aids lung inflation.

Question 4

A lone rescuer finds a 10-month-old infant in cardiac arrest. An AED with only adult-sized pads is available. What is the most appropriate action regarding AED pad placement?

Accepted Answer

Place one pad on the center of the infant's chest and the other on the back, ensuring they do not touch.

Answer

Do not use the AED, as adult pads will deliver an excessive shock.

Answer

Cut the adult pads to better fit the infant's torso before applying.

Answer

Place both pads side-by-side on the infant's chest, even if they overlap slightly.

Question 5

To ensure high-quality CPR and maximize coronary perfusion pressure, interruptions in chest compressions should be limited to no more than:
