What safety instruction should the nurse include in discharge teaching for a client prescribed isosorbide dinitrate?

Isosorbide dinitrate is a vasodilator commonly used for the management of angina pectoris. One of the crucial safety instructions for clients taking this medication involves the risk of orthostatic hypotension, which can lead to dizziness or fainting when standing up rapidly. Therefore, advising the patient to always rise slowly from sitting or lying positions can significantly help mitigate this risk, promoting safety and minimizing the likelihood of injury from falls.

This option is particularly relevant because dizziness is a common side effect associated with vasodilators due to their effects on blood pressure. The other answers, while potentially relevant in different contexts, do not directly address the specific safety concern associated with isosorbide dinitrate usage.
