A client on amlodipine (Norvasc) experiences chest pain. Which condition should the nurse monitor for after administering sublingual nitroglycerin?

The correct answer is hypotension, which is an important consideration after administering sublingual nitroglycerin, especially in a client who is already on amlodipine. Both amlodipine, a calcium channel blocker, and nitroglycerin can lead to vasodilation, which reduces blood pressure. When nitroglycerin is administered, there is a risk of further lowering blood pressure, potentially leading to symptomatic hypotension, characterized by dizziness, lightheadedness, or fainting.

Monitoring for hypotension is crucial because the combined effects of these two medications can enhance the risk of excessive blood pressure reduction, particularly if the patient is also experiencing chest pain, which may already place increased strain on the cardiovascular system. The patient’s response to nitroglycerin, particularly in terms of blood pressure, should be closely observed to ensure safe and effective management of their anginal symptoms.
