What is the primary purpose of antiembolic stockings?

The primary purpose of antiembolic stockings is to prevent blood clots. These specialized stockings are designed to apply graduated compression to the legs, which helps to promote venous blood flow and reduce the risk of thrombus formation, especially in individuals who are immobile or undergoing surgical procedures. By improving the circulation of blood back toward the heart, they effectively minimize the risk of deep vein thrombosis (DVT), a type of clot that can develop in the deep veins of the legs.

While improving circulation is a component of how antiembolic stockings function, it is specifically their role in preventing blood clots that is the most critical aspect. The stockings do not serve a primary function in preventing infections or enhancing skin hydration, which are not related to their intended use. Thus, the focus on clot prevention makes this the correct answer.
