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

A. "I know I will need to take methimazole for the rest of my life.": Methimazole therapy is often temporary, used to control hyperthyroidism until definitive treatment or remission occurs. Lifelong use is not necessarily required. B. "I should take methimazole 1 hr before eating.": Methimazole can be taken with or without food. Timing relative to meals is not critical for its absorption, so taking it strictly one hour before eating is unnecessary. C. "I should be vigilant with birth control while taking methimazole.": Methimazole can be teratogenic, especially during the first trimester of pregnancy. Effective contraception is important to prevent fetal harm while on this medication. D. "I should stop taking methimazole when my night sweats go away.": Symptoms may improve before thyroid hormone levels normalize. Stopping methimazole prematurely can lead to relapse of hyperthyroidism, so discontinuation should only occur under provider guidance.
