Certified Medication Aide Practice

Diuretics are medications designed to increase the production of urine by the kidneys, ultimately helping the body get rid of excess water and salt through urine. This can help reduce the amount of fluid in the body, which is particularly useful in conditions such as high blood pressure, heart failure, and edema. Therefore, the correct answer is D: Rid the body of excess water.

Options A, B, and C are incorrect because diuretics are not used to regulate the heart beat, relieve nausea and vomiting, or promote healing of ulcers.
