A nurse is providing teaching to a client who has a new prescription for methimazole for the treatment of hyperthyroidism. Which of the following statements by the client indicates an understanding of the teaching?

A. "This medication can cause constipation": Methimazole is more likely to cause symptoms such as rash, fever, or agranulocytosis, rather than constipation. Constipation is not a common side effect of this medication. B. "I will contact the provider if my throat becomes sore": Methimazole can cause agranulocytosis, a condition that reduces white blood cells and increases the risk of infection. A sore throat could indicate this side effect, and the client should contact the provider immediately. C. "I will weigh myself once a week while on this medication": Regular weight monitoring may be helpful for managing hyperthyroidism, but it is not the primary concern with methimazole. The focus should be on monitoring for signs of infection or hematologic issues. D. "This medication should be taken as needed when symptoms occur": Methimazole should be taken regularly as prescribed, not on an as-needed basis. Consistent use is necessary to manage hyperthyroidism and prevent complications.
