Chronic venous insufficiency can lead to ulceration. Which of the following is a recommended preventive measure?

Chronic venous insufficiency occurs when the veins have difficulty sending blood from the legs back to the heart, leading to symptoms such as swelling, pain, and, ultimately, ulceration. Elevating the legs above heart level is a recommended preventive measure because it helps facilitate venous return by using gravity to assist in draining excess fluid from the lower extremities. This position can decrease swelling and pressure in the veins, which can be beneficial for individuals experiencing reduced venous circulation.

In contrast, restricting fluid intake is not typically advised, as it can lead to dehydration and may exacerbate other health issues. Using compression stockings when sedentary is also a good preventive measure, but elevation of the legs specifically targets the reduction of swelling and supports venous return more actively. Meanwhile, reducing physical activity is generally discouraged, as regular movement is important in promoting circulation and preventing the stagnation of blood in the veins. Thus, elevating the legs is indeed an effective strategy for preventing complications associated with chronic venous insufficiency.
