PALS High-Quality Pediatric BLS 5

Question 1

A child receives high-quality CPR for 2 minutes. The AED analyzes and advises 'no shock.' What is the NEXT step?

Accepted Answer

Immediately resume CPR for another 2 minutes

Answer

If the AED advises no shock, immediately resume CPR beginning with compressions to minimize interruptions to perfusion.

Question 2

Which of the following is a sign that CPR compressions are adequate during pediatric resuscitation?

Accepted Answer

Palpable pulse with each compression

Answer

A palpable pulse (often femoral or carotid) synchronized with each compression confirms that adequate forward flow is being generated.

Question 3

In pediatric BLS, 'push hard and push fast' refers to which specific targets?

Accepted Answer

Depth ≥ 1/3 AP diameter; rate 100–120/min

Answer

High-quality pediatric CPR requires compressing at least 1/3 the AP chest diameter at a rate of 100–120 compressions per minute.

Question 4

A rescuer is providing bag-mask ventilation to a child in cardiac arrest. Which mask size selection principle applies?

Accepted Answer

The mask should cover the mouth and nose with an airtight seal

Answer

The correctly sized mask covers both the mouth and nose completely, allowing an airtight seal for effective ventilation.

Question 5

Why is it important to avoid excessive ventilation during pediatric CPR even when a bag-mask is available?

Accepted Answer

It raises intrathoracic pressure, decreasing cardiac output and coronary perfusion

Answer

Over-ventilation raises intrathoracic pressure, impeding venous return and severely reducing cardiac output during CPR.
