Final answer:
An effective preventive measure for deep vein thrombosis in post-surgical patients is to encourage range of motion and ambulation, as movement helps the leg muscles push blood through the veins and prevents clotting. Option c.
Step-by-step explanation:
An effective preventive measure for a post-surgical client at risk for developing deep vein thrombosis (DVT) is to encourage range of motion and ambulation. When a patient is mobile, the muscles in the legs help push blood through the veins, which can prevent blood from pooling and clotting. While wearing graduated compression stockings can also help by providing increased pressure supporting blood flow back up to the heart, they should not replace the need for movement and exercise.
For patients unable to frequently ambulate, such as during long-haul flights or due to medical conditions, it's recommended to perform leg exercises to stimulate circulation. Additionally, avoiding long periods of standing or sitting and frequently elevating the legs can contribute to preventing DVT. The skeletal muscle pump plays a crucial role in the circulation of blood, particularly in the legs, and exercising these muscles is beneficial in reducing the risk of DVT.
