A nurse at an outpatient clinic receives a call from a client who reports experiencing syncope after starting a new prescription for enalapril. Which of the following instructions should the nurse give the client?

Orthostatic hypotension, which is a sudden drop in blood pressure upon standing, can be a side effect of enalapril and may lead to syncope. Instructing the client to rise slowly from a sitting to a standing position helps minimize the risk of a sudden drop in blood pressure and decreases the chances of syncope occurring. Decreasing fluid intake is not likely to be the cause of syncope related to enalapril. It is important for clients to maintain adequate hydration, especially if they are experiencing side effects such as orthostatic hypotension. While a low pulse rate may indicate bradycardia, it is not the primary concern in this situation. Orthostatic hypotension leading to syncope is the main issue, and the client should be instructed to rise slowly to prevent it. While enalapril is an angiotensin-converting enzyme (ACE) inhibitor that can increase potassium levels in the blood, it is not directly related to syncope. Dietary changes should be made under the guidance of a healthcare provider based on individual needs and blood test results.
