Answer to Question 1

ANS: C
Patients who take steroids need extra steroid before situations that cause stress, such as surgery. Failure to administer the increased dose can prove fatal. For surgeries that cause moderate stress, such as a cholecystectomy, patients should be given 50 to 75 mg of hydrocortisone intravenously the day of the procedure, followed by a taper over 1 to 2 days to the usual replacement dose. Giving the usual dose or giving an increased oral dose is not indicated.

Answer to Question 2

ANS: D
The role of drugs in the treatment of Cushing's syndrome is limited; drugs are used only as adjuncts to surgery and radiation therapy. The most effective agent is ketoconazole, which suppresses steroid synthesis. Cosyntropin is used to diagnose adrenal insufficiency. Dexamethasone is a glucocorticoid used for replacement therapy and to diagnose Cushing's syndrome. Fludrocortisone is used for chronic mineralocorticoid replacement.
