Which statement from a client receiving discharge teaching about digoxin and a sodium-restricted diet indicates a need for further teaching?

When considering the context of a sodium-restricted diet, the statement about using a little table salt on food indicates a need for further teaching. Clients on a sodium-restricted diet are typically advised to minimize their sodium intake as much as possible to manage conditions like heart failure or hypertension. Even small amounts of added table salt can contribute to overall sodium intake and potentially counteract the benefits of dietary restrictions designed to help with their condition.

In contrast, the other statements reflect appropriate and safe knowledge concerning digoxin and a sodium-restricted diet. Checking the pulse is essential because digoxin can affect heart rate, and monitoring this helps in recognizing any issues. Gradually increasing exercise with rest periods is a sensible approach to maintaining activity while considering the client's condition. Calling a healthcare provider if there are breathing difficulties when lying flat is also appropriate, as this can indicate worsening heart failure, requiring timely medical attention. Therefore, the selected statement reveals a misunderstanding of the dietary restrictions necessary for the client's health management.
