Which instruction about lisinopril is most important for a client to follow at discharge?

Lisinopril, an ACE inhibitor commonly used for managing hypertension and heart failure, can cause orthostatic hypotension, particularly in the initial stages of treatment or after dosage adjustments. This side effect occurs when blood pressure drops significantly upon standing, which can lead to dizziness or fainting. Therefore, advising the client to rise slowly and sit on the side of the bed before standing is essential to prevent potential falls and ensure patient safety.

While it is important for clients to monitor their potassium intake because lisinopril can increase potassium levels, and performing regular blood work may be part of their care plan, the immediate instruction on how to safely transition from lying or sitting to standing is crucial for avoiding acute complications related to blood pressure. Monitoring pulse is generally not a standard requirement for lisinopril, making the advice to rise slowly the most critical instruction at discharge.
