Free CPR Chest Compressions & Defibrillation Questions and Answers

Question 1

What is the correct hand placement for adult chest compressions?

Accepted Answer

On the lower half of the sternum

Answer

The correct hand placement for adult chest compressions is on the lower half of the sternum, in the center of the chest. This position ensures that compressions are delivered directly over the heart, maximizing effectiveness. Proper placement also helps avoid injury to other organs or the xiphoid process.

Question 2

What is the appropriate depth of chest compressions for children during CPR?

Accepted Answer

2 inches

Answer

For children during CPR, the appropriate depth of chest compressions is about 2 inches (5 cm), or approximately one-third the depth of the chest. This depth is crucial for effectively circulating blood to vital organs. It balances the need for adequate compression with the child's smaller body size to prevent injury.

Question 3

Which of the following improves the effectiveness of chest compressions?

Accepted Answer

Allowing full chest recoil

Answer

Allowing full chest recoil significantly improves the effectiveness of chest compressions. Full recoil permits the heart to refill completely with blood between compressions, maximizing the amount of blood pumped with each subsequent compression. Leaning on the chest prevents this vital refilling and reduces blood flow.

Question 4

How long should interruptions in chest compressions be limited to?

Accepted Answer

10 seconds

Answer

Interruptions in chest compressions should be limited to no more than 10 seconds. Minimizing these interruptions is critical because blood flow to the brain and heart stops when compressions cease. Prolonged pauses can significantly reduce the chances of survival during cardiac arrest.

Question 5

When using an AED, what is the first step after turning it on?

Accepted Answer

Attach electrode pads

Answer

When using an AED, the first step after turning it on is to attach the electrode pads to the victim's bare chest. This allows the AED to analyze the heart's electrical rhythm. Without the pads properly attached, the device cannot assess whether a shock is needed.
