Question
The nurse provides discharge teaching to a client starting methimazole. Which statement by the client indicates correct understanding?
1I will avoid thyroid-function testing because methimazole makes the results unreliable.
2I will increase seaweed and iodine supplements to strengthen the medication effect.
3I will report fever or a sore throat immediately and expect a white-cell count.✓ Correct answer
4I will stop the medication after one week if my tremor and palpitations improve.
Explanation
Methimazole can cause potentially life-threatening agranulocytosis. Fever, sore throat, or other evidence of illness must be reported immediately, and a white-blood-cell count with differential is obtained to evaluate for neutropenia. Thyroid-function tests are monitored to guide dosing. Iodine supplements and early medication discontinuation should not be undertaken without prescriber direction.
Clinical reasoning Agranulocytosis can remove the neutrophil response needed to contain infection. Fever or sore throat during methimazole therapy is therefore a safety signal rather than a routine viral complaint.
Decision rule Report infection symptoms immediately and obtain a white-cell count with differential; if agranulocytosis is confirmed, methimazole is discontinued under prescriber management.
Key concepts
Agranulocytosis — A potentially life-threatening reduction in granulocytes that can present with fever, sore throat, mouth ulcers, or other infection symptoms.
Methimazole monitoring — Care includes thyroid-function testing and immediate evaluation of infection symptoms with a white-cell count and differential.
