After a set of 50 compressions, give the client 2 rescue breaths.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

While it’s important to start CPR as soon as possible, the AED should be attached as soon as it’s available.

Choice B rationale:

The American Heart Association recommends providing chest compressions at a rate of 100-120/min during CPR.

Choice C rationale:

Checking for a brachial pulse is not a priority during CPR. The focus should be on providing chest compressions and rescue breaths.

Choice D rationale:

The correct ratio of compressions to breaths during CPR is 30:2, not 50:2.

Correct Answer is C

Explanation

Choice A rationale:

The thickest part of the heart is not the upper chambers but the lower chambers, specifically the left ventricle. This is because it needs to pump blood to the entire body.

Choice B rationale:

Blood leaves the heart through the lower chambers, or ventricles, not the upper chambers.

Choice C rationale:

Blood enters the heart through the upper chambers, or atria. This is where deoxygenated blood from the body and oxygenated blood from the lungs first enter the heart.

Choice D rationale:

The term “ventricles” refers to the lower chambers of the heart, not the upper chambers.
