B．diabetes mellitus.
C．adrenal crisis.
D．diabetes insipidus.
答案
参考答案：D
解析：Diabetes insipidus is an abrupt onset of extreme polyuria that commonly occurs in clients after brain surgery. Cushing's syndrome is excessive glucocorticoid secretion resulting in sodium and water retention. Diabetes mellitus is a hyperglycemic state marked by polyuria, polydipsia, and polyphagia. Adrenal crisis is undersecretion of glucocorticoids resulting in profound hypoglycemia, hypovolemia, and hypotension.
