Question: 1 / 400

What is the primary purpose of diuretics in managing hypertension?

To increase heart rate

To promote water retention

To decrease blood volume

Diuretics are primarily used in managing hypertension because they effectively decrease blood volume. By promoting the excretion of sodium and water through the kidneys, diuretics help reduce the overall volume of blood circulating in the bloodstream. When blood volume is lowered, it leads to decreased pressure against the walls of the blood vessels, which is essential for managing hypertension. This reduction in blood volume translates directly into lower blood pressure, making diuretics a foundational treatment option for individuals with high blood pressure.

The other choices do not align with the primary function of diuretics. Increasing heart rate would counteract the desired effects of managing hypertension, promoting water retention contradicts the purpose of diuretics, and enhancing sodium absorption does not reflect the action of diuretics, which is to promote sodium excretion.
