Correct Answer: 1,2
Rationale 1: Intravenous corticosteroids may be ordered to treat acute hyperthyroid states because they block the conversion of T4 to T3 in peripheral tissues.
Rationale 2: Severe hyperthyroid states create high levels of stress that deplete adrenal corticosteroids in the body, and the administration of replacement doses is necessary.
Rationale 3: Steroids do not reduce the TSH level.
Rationale 4: Steroids are not used to maintain the blood pressure in thyroid storm.
Rationale 5: Steroids are not used to stabilize the heart rate in thyroid storm.
