22. The answer is c. （Brunicardi, pp 1463-1465.） Acute adrenal insufficiency can occur in patients with severe stress, infection, or trauma or as a result of abrupt cessation or too rapid tapering of chronic glucocorticoid therapy, and is classically manifested as changing mental status, increased temperature, cardiovascular collapse, hypoglycemia, and hyperkalemia. The diagnosis can be difficult to make and requires a high index of suspicion. Its clinical presentation is similar to that of sepsis; however, sepsis is generally associated with hyperglycemia and no significant change in potassium. The treatment for adrenal crisis is intravenous steroids, volume resuscitation, and other supportive measures to treat any new or ongoing stress. Dexamethasone is the steroid replacement of choice when empirically treating adrenal insufficiency since hydrocortisone can interfere with confirmatory testing （adrenocorticotropic hormone [ACTH] stimulation test）. Steroid treatment can be subsequently converted to oral medication and tapered after treatment of the adrenal crisis. 23. The answer is e. （Brunicardi, p 78.） Transfusions with FFP to replenish vitamin K-dependent dotting factors should be administered on call to the operating room. The timing of transfusion is dependent on the quantity of each factor delivered and its half-life. The half-life of the most stable dotting factor, factor VII, is 4 to 6 hours. Thus, transfusion of FFP on call to the operating room ensures that the transfusion is complete prior to the incision, with circulating factors to cover the operative and immediate postoperative period.
