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 C

Explanation

Choice A rationale:

Tilt the head and lift the chin is a technique used to open the airway in an unconscious client, not a conscious one with an airway obstruction.

Choice B rationale:

Turning the client to the side is not the first action to take when a client is conscious and has an airway obstruction.

Choice C rationale:

The Heimlich maneuver is the appropriate action to take for a conscious client who has an airway obstruction. It works by creating an artificial cough, intended to force the obstruction out.

Choice D rationale:

A blind finger sweep should never be performed because it can push the obstruction further into the airway.

A. Repeat the potassium level. B. Withhold the medication. C. Monitor for paresthesia. D. Administer a hypertonic solution.

Correct Answer is B

Explanation

Choice A rationale:

Repeating the potassium level is not the first action to take. The nurse already has a recent lab value.

Choice B rationale:

The nurse should withhold the medication. The normal range for potassium is 3.5-5.0 mEq/L. A level of 5.5 mEq/L is high, so giving more potassium could lead to hyperkalemia.

Choice C rationale:

Monitoring for paresthesia is important in hyperkalemia, but it is not the first action. The nurse should first prevent further increase in potassium levels.

Choice D rationale:

Administering a hypertonic solution is not relevant in this situation. It does not directly address the high potassium level.
