What causes diabetes insipidus?
Insufficient antidiuretic hormone (ADH) production
Overproduction of antidiuretic hormone (ADH)
Overproduction of insulin
Insufficient insulin production
The Correct Answer is A
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.
