Therefore, the nurse should closely monitor the client for any signs of hemorrhage, such as unexplained bruising, bleeding gums, or blood in the urine or stools.

Correct Answer: B

Rationale: Nitroglycerin is a rapid-acting medication used to relieve angina pain by dilating blood vessels. The correct administration is to take one tablet every 5 minutes as needed, up to three doses. If chest pain persists after three doses, the client should seek emergency medical attention as it can indicate a more serious cardiac issue.

Correct Answer: A

Rationale: Enalapril, an ACE inhibitor, can lead to hypotension, particularly following the initial dose or dosage escalation. This effect is due to the medication's mechanism of action in dilating blood vessels, which can result in lowered blood pressure. Monitoring for hypotension is crucial to prevent complications such as dizziness, lightheadedness, or fainting in clients taking enalapril.

Correct Answer: C

Rationale: Hypokalemia increases the risk of digoxin toxicity as low potassium levels enhance the effects of digoxin on the heart, leading to toxicity and potential adverse effects.
