TEST BANK FOR UNDERSTANDING PHARMACOLOGY ESSENTIALS FOR MEDICATION SAFETY 2ND EDITION BY WORKMAN 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. lOMoAR cPSD| Downloaded by Elizabeth Whitney () DIF: Cognitive Level: Remembering REF: p. 239 2.
