The following are treatment options for hyperthyroidism associated with Graves' disease EXCEPT

• A. Thyroid hormone
• B. PTU
• C. Beta-blockers
• D. Radioactive iodine

Answer: (A)

In Graves' disease, the goal is to lower the effects of excess thyroid hormone or reduce its production. Treatments typically include antithyroid drugs (such as PTU) that inhibit thyroid hormone synthesis, beta-blockers to alleviate adrenergic symptoms (like tachycardia and tremor), and radioactive iodine to destroy overactive thyroid tissue. Giving thyroid hormone would worsen hyperthyroidism by increasing circulating thyroid hormone levels, so it is not a treatment for Graves' hyperthyroidism. Thyroid hormone is used only when needed to replace hormone after thyroid failure or surgical removal, not to treat active hyperthyroidism.
