Methimazole (Tapazole)
Propylthiouracil (PTU)
Calcium gluconate
The Correct Answer is C

Correct Answer is C
Explanation
Thyroid storm is associated with sympathetic nervous system stimulation, leading to increased release of thyroid hormones from the thyroid gland. This results in a cascade of hypermetabolic effects throughout the body.
Correct Answer is B
Explanation
Excessive iodine intake, such as from contrast agents used in imaging studies, can trigger thyroid storm in individuals with underlying hyperthyroidism. The additional iodine can stimulate further thyroid hormone release and exacerbate the condition.
Incorrect choices:
