Cosyntropin is used to diagnose adrenal insufficiency, which this patient shows signs of having. Dexamethasone is used to diagnose Cushing's syndrome. Fludrocortisone, a mineralocorticoid, is used with hydrocortisone to treat primary adrenal insufficiency; both of these drugs will be administered after the diagnosis has been confirmed.
