Which topic will the nurse plan to include in discharge teaching for a patient with heart failure with reduced ejection fraction (HFrEF)?

Correct Answer: D

Rationale: The core measures for the treatment of heart failure established by The Joint Commission indicate that patients with an ejection fraction below 40% should receive an ACE inhibitor to decrease the progression of heart failure. Aerobic exercise may not be appropriate for a patient with this level of heart failure, salt substitutes are not usually recommended because of the risk of hyperkalemia, and the patient will need to see the primary care provider more frequently than annually.

Correct Answer: B

Rationale: The common carotid artery typically bifurcates into internal and external carotid arteries at the C3-C4 level.

Correct Answer: C

Rationale: The AV bundle (AV node) has the slowest conduction to delay the impulse, allowing atrial contraction before ventricular.

Correct Answer: A

Rationale: Right heart failure increases right atrial pressure due to backflow from the failing right ventricle.

Correct Answer: C

Rationale: Without an ECG, 100 bpm is a common normal value for illustrative purposes; actual calculation requires ECG data.
