What is the purpose of anti-embolism stockings?

Anti-embolism stockings are specifically designed to promote blood circulation and reduce the risk of blood clots, particularly in patients who may be immobile or have limited mobility. They apply graduated compression to the legs, which helps to encourage venous return of blood back to the heart, effectively reducing the pooling of blood in the lower extremities. This is crucial in preventing conditions such as deep vein thrombosis (DVT), which can lead to serious complications like pulmonary embolism. Enhanced circulation also aids in decreasing swelling and provides support to the veins during prolonged periods of immobility.

While the other options mention various health concerns or effects, they do not focus on the primary function of anti-embolism stockings as efficiently as the correct answer does. For example, the prevention of urinary incontinence and maintaining body temperature are not related to the function of these stockings, and although enhancing mobility can be a positive outcome of improved circulation, the primary purpose remains centered on supporting blood flow and preventing clot formation.
