A nurse is reinforcing teaching with a client following surgery who has antiembolism stockings in place. Which of the following information should the nurse include in the teaching?

Choice A rationale Antiembolism stockings are a mechanical method to enhance venous return and reduce stasis; however, they do not replace the physiological benefits of postoperative leg exercises (e.g., ankle pumps). Exercises actively contract the calf muscles, powerfully activating the skeletal muscle pump, which is essential for maximizing blood flow velocity and preventing stasis. Choice B rationale The primary function of antiembolism stockings is to apply graduated external compression to the legs, which narrows the diameter of the veins, increasing the velocity of venous blood flow. This hemodynamic effect prevents venous stasis and reduces the risk of thrombosis; pain reduction is an associated effect of managing swelling, not the main objective. Choice C rationale Antiembolism stockings are mainly used to prevent Deep Vein Thrombosis (DVT) by mitigating venous stasis, especially in immobile clients. While the compression they provide may help support vein walls, their effect on preventing varicose veins, which are permanent dilations due to valvular incompetence, is secondary and not their primary post-operative indication. Choice D rationale The application of graduated compression from the ankle upwards systematically reduces the caliber of the superficial veins and the deep veins, which consequently increases the linear velocity of venous blood flow. This hemodynamic change is the direct mechanism by which antiembolism stockings effectively prevent venous stasis and subsequent thrombus formation.
