Correct answer: D — Give a thionamide, then iodine, plus beta blockade as tolerated and glucocorticoid
The best answer is “Give a thionamide, then iodine, plus beta blockade as tolerated and glucocorticoid”. Thyroid storm requires simultaneous supportive care, adrenergic control, thionamide therapy, iodine after thionamide and glucocorticoid. Giving iodine first can supply substrate for new hormone synthesis; radioiodine acts too slowly and surgery generally follows stabilization.
