Answer to Question 1

ANS: C
Cushing disease and Addison disease are related to elevated levels of ACTH, not ADH, estro-gen, or aldosterone.

Answer to Question 2

ANS: D
With elevated cortisol levels, vascular sensitivity to catecholamines increases significantly, lead-ing to vasoconstriction and hypertension. Tachycardia is more likely than bradycardia due to in-creased sensitivity to catecholamines. Tachypnea does not occur; the patient experiences hyper-tension. Hyokalemia, not hyperkalemia, occurs.
