A nurse is reinforcing teaching with a client who has diabetes mellitus and a new prescription for prednisone. Which of the following statements indicates an understanding of the teaching?

A. "I might notice a decrease in my blood sugar while taking this medication." Prednisone can cause an increase in blood sugar levels, not a decrease. B. "I should expect to feel hungrier while on this medication." Corticosteroids like prednisone can increase appetite, leading to potential weight gain. C. "I might have a fever while taking this medication." While corticosteroids can affect immune function, they are not typically associated with causing fever directly. D. "This medication can cause ringing in my ears." Ringing in the ears (tinnitus) is not a common side effect of prednisone.
