-A patient who cannot walk because of severe arthritis develops edema in both ankles. Based on your understanding of edema, capillary pressure, and mechanisms of capillary exchange, which action would help decrease the patient's edema?
A) Restrict fluid intake.
B) Elevate the patient's legs.
C) Provide a high-protein diet.
D) Increase fluid intake.

Question

Quizplus · Accepted Answer

Elevating the legs will help to decrease edema by increasing venous return and reducing capillary hydrostatic pressure, allowing fluid to flow out of the tissues and back into the bloodstream. Restricting fluid intake may help prevent further fluid buildup, but it will not address the underlying cause of the edema. Providing a high-protein diet and increasing fluid intake have no direct effect on edema.
