The nurse preceptor is teaching a newly licensed nurse about blood flow through the heart.
The nurse preceptor knows teaching has been effective when the newly licensed nurse states that the upper chambers of the heart are:.

The thickest part of the heart.

Where blood leaves.

Where blood enters.

Called ventricles.

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is ["1100"]

Explanation

The correct answer is 1100.

Calculation: The current time is 0700 and there are 300 mL remaining in the bag. The IV is infusing at a rate of 75 mL/hr. Therefore, 300 mL ÷ 75 mL/hr = 4 hours. Adding 4 hours to the current time of 0700 gives 1100.
