What is the purpose of elastic stockings?

To completely restrict blood flow
To help maintain blood flow and reduce discomfort and swelling
To provide warmth to the legs
To prevent movement in the legs

The correct answer is: To help maintain blood flow and reduce discomfort and swelling

The purpose of elastic stockings primarily revolves around enhancing circulation and alleviating discomfort and swelling in the legs. These stockings are designed to apply graduated compression, which means that they are tighter at the ankle and gradually decrease in pressure as they move up the leg. This compression supports venous return, helping to push blood back toward the heart and reduce the pooling of blood in the lower extremities. Using elastic stockings can significantly benefit individuals who may be at risk for conditions such as deep vein thrombosis (DVT) or those who experience varicose veins or chronic venous insufficiency. Beyond circulation assistance, these stockings can also help minimize symptoms of edema by containing excess fluid in the tissues, providing comfort and improving overall leg health. The other options do not accurately reflect the primary benefits of elastic stockings, as they do not restrict blood flow, provide warmth, or prevent movement in the legs. Instead, they facilitate better blood flow and are integral to managing leg health.
