What condition is caused by a benign tumor of the adrenal medulla that secretes epinephrine and norepinephrine?
Cushing syndrome
Addison disease
Graves’ disease
Pheochromocytoma
The Correct Answer is D
Choice A rationale
Cushing syndrome is caused by chronic high blood levels of cortisol or related corticosteroids.
Choice B rationale
Addison disease is a disorder in which the adrenal glands don’t produce enough hormones.
Choice C rationale
Graves’ disease is an autoimmune disorder that causes hyperthyroidism, not a benign tumor of the adrenal medulla.
Choice D rationale
Pheochromocytoma is a rare, usually noncancerous (benign) tumor that develops in cells in the center of an adrenal gland. This tumor can release hormones that can cause a persistent or episodic increase in blood pressure.

Correct Answer is A
Explanation
Choice A rationale
Diabetes insipidus is a rare disorder that occurs when a person’s kidneys pass an abnormally large volume of urine that is insipid—dilute and odorless. In most people, the kidneys pass about 1 to 2 quarts of urine a day. In people with diabetes insipidus, the kidneys can pass 3 to 20 quarts of urine a day. As a result, a person with diabetes insipidus may feel the need to drink large amounts of liquids.
Choice B rationale
Overproduction of antidiuretic hormone (ADH) leads to Syndrome of Inappropriate Antidiuretic Hormone (SIADH), not diabetes insipidus.
Choice C rationale
Overproduction of insulin can lead to hypoglycemia, not diabetes insipidus.
Choice D rationale
Insufficient insulin production leads to diabetes mellitus, not diabetes insipidus.

Choice C rationale
