A nurse is assessing a client who has Graves' disease and is taking methimazole. Which of the following findings indicates the client needs a lower dose of the medication?

A. Exophthalmos: Exophthalmos, or bulging eyes, is a hallmark sign of Graves' disease caused by autoimmune inflammation. It is not directly influenced by methimazole dosing and may persist despite appropriate medication therapy. B. Weight loss: Weight loss is a symptom of hyperthyroidism, which methimazole is used to treat. If a client continues to lose weight, it could suggest under-treatment, not over-treatment, so a lower dose would not be appropriate in this case. C. Diaphoresis: Diaphoresis (excessive sweating) is associated with high thyroid hormone levels. Its presence suggests persistent hyperthyroidism and the need for continued or increased methimazole dosing rather than a reduction. D. Bradycardia: Bradycardia is a sign of hypothyroidism, which can occur if methimazole suppresses thyroid hormone production too much. This indicates that the current dose may be too high and should be reduced to prevent further hypothyroid effects.
