What should a nurse instruct a client taking Prazosin and with a blood pressure of 100/60 mmHg?

Instructing the client to stand up slowly is particularly important for individuals taking Prazosin, which is an alpha-blocker used to treat hypertension and symptoms of benign prostatic hyperplasia. This medication can lead to orthostatic hypotension, a condition where blood pressure drops significantly when a person transitions from sitting or lying down to a standing position. This can cause dizziness, lightheadedness, or even fainting.

By advising the client to stand up slowly, the nurse helps to mitigate the risk of these symptoms occurring. The gradual change in position allows the body's cardiovascular system to compensate for the shift in blood flow, thus helping maintain stable blood pressure. This precaution is essential, especially given the client's current blood pressure of 100/60 mmHg, which indicates a lower-than-normal blood pressure that might increase the risk of orthostatic changes.
