What strategy should a nurse use to minimize the risk of venous stasis in a postoperative patient?

Assisting with early ambulation is an effective strategy to minimize the risk of venous stasis in a postoperative patient. Early ambulation promotes blood circulation, which helps prevent the formation of blood clots in the veins of the legs. When patients begin to move shortly after surgery, it encourages the flow of blood and helps to avoid the stagnation that can lead to complications such as deep vein thrombosis (DVT). Movement activates the calf muscles, which act as a pump for the venous system, enhancing venous return to the heart.

In contrast, placing pillows under the knee may create a situation where the blood flow is impeded, potentially leading to increased risk of stasis. Sitting with feet flat on the floor is supportive but does not actively promote circulation like ambulation does and can still result in prolonged periods of immobility if not combined with other movements. Performing gentle leg massage can offer comfort but may not provide the same level of benefit in promoting circulation and reducing venous stasis as getting the patient up and moving. Therefore, early ambulation is the most effective strategy to enhance venous return and maintain healthy circulation in postoperative patients.
