Which statement by a client taking carvedilol indicates an understanding of discharge instructions?

The statement about avoiding salt substitutes that contain potassium demonstrates a clear understanding of the discharge instructions for a client taking carvedilol. Carvedilol is a non-selective beta-blocker often prescribed for heart failure, hypertension, or to protect the heart after a myocardial infarction. One of the common concerns with medications like carvedilol is the balance of electrolytes, particularly potassium.

Clients on carvedilol need to be cautious about their potassium levels, especially if they also have conditions that require dietary restrictions on potassium intake. Salt substitutes frequently contain potassium chloride, which could lead to hyperkalemia (elevated potassium levels) when combined with the effects of carvedilol and other medications that may influence potassium balance.

This awareness indicates that the client is actively engaging with their treatment plan and is informed about how certain dietary choices can impact their health while under this medication.
