A nurse is reviewing discharge instructions with a client who has rheumatoid arthritis and a new prescription for prednisone. Which of the following statements by the client indicates an understanding of the teaching?

The correct answer is B: "I should eat more bananas while taking this medication." Bananas are a good source of potassium, which can help counteract the potassium-depleting effects of prednisone. Prednisone can lead to low potassium levels, so increasing intake of potassium-rich foods like bananas is important.

Incorrect options:
A: Taking a flu vaccine within one week of starting prednisone is not necessary for managing rheumatoid arthritis.
C: Aspirin is not recommended with prednisone due to increased risk of gastrointestinal bleeding.
D: Sore throat is not a common side effect of prednisone and should be reported to the healthcare provider if it occurs.
