What intervention is crucial for a nurse to implement to prevent complications in a postoperative client at risk for VTE?

Encouraging regular ambulation is a crucial intervention for preventing complications, specifically venous thromboembolism (VTE), in a postoperative client. After surgery, patients are often immobilized, which increases the risk of blood clots forming in the veins, especially in the lower extremities. Ambulation promotes venous return and helps to maintain circulation, reducing stasis in the veins that can lead to clot formation.

In addition to preventing VTE, regular ambulation offers several other benefits: it encourages optimal respiratory function, decreases the risk of other complications such as pneumonia, and enhances overall recovery by promoting muscle strength and endurance.

While leg elevation during rest can be beneficial for reducing swelling and promoting venous return, it is not as effective as ambulation in preventing VTE. Leg massages may seem helpful, but they could potentially dislodge existing clots or initiate clot formation in some patients. Limiting fluid intake is contrary to the goals of postoperative care, as hydration is important for maintaining circulation and preventing complications. Therefore, regular ambulation stands out as a key intervention for ensuring the patient's safety and preventing VTE after surgery.
