Chapter 15: Drugs That Affect Urine Output

MULTIPLE CHOICE

BASIC CONCEPTS

1. What is the main intended action of any type of diuretic
drug? a. Weight loss

b. Potassium loss

c. Increased urine output d.
Decreased sense of thirst
ANS: C

Diuretics are drugs that help rid the body of excess water and sodium by
increasing a

person’s urine output. They may work on the kidneys directly or may
increase blood flow

to the kidney. Either way, these drugs cause a person to urinate more and
lose water from
the body. Although potassium is often lost with a diuretic that is not a diuretic’s
main

intended action.
