A nurse is caring for a client who is postoperative and is at risk for developing venous thromboembolism (VTE). The nurse should instruct the client to avoid which of the following unsafe actions?

Rationale: A. Ambulating soon after surgery: Early ambulation promotes circulation, reduces venous stasis, and is one of the safest and most effective ways to prevent VTE after surgery. B. Elevating her feet: Elevation supports venous return to the heart, decreases pooling of blood in the lower extremities, and reduces the risk of clot formation. C. Flexing her ankles: Ankle flexion exercises encourage calf muscle contraction, enhance blood flow, and prevent venous stasis, making them beneficial for VTE prevention. D. Massaging her legs: Massaging the legs of a client at risk for VTE can dislodge an existing clot, increasing the risk of pulmonary embolism, which makes it unsafe.
