There are no chambers.

B.

Large chambers called ventricles.

C.

Small chambers called ventricles.

D.

Large chambers called the atrium.

This statement is correct. The heart has two large chambers called ventricles that pump blood out of the heart.

This statement is incorrect because the atria are the smaller chambers of the heart, not the larger ones.

Correct Answer is A

Explanation

Choice A rationale:

Asking the client’s full name and date of birth is the most reliable method of identification.

Choice B rationale:

Verifying the client’s room number is not reliable because room assignments can change.

Choice C rationale:

Asking a family member to verify the client’s identity is not always possible or reliable.

Choice D rationale:

Checking the client’s name on the medication administration record (MAR) is important but should be done in conjunction with direct client identification.

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.
