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?

Choice A reason: Elevating the feet is generally a safe and recommended practice for postoperative patients at risk for VTE. It promotes venous return and reduces stasis in the lower extremities, which helps prevent clot formation. This action is not contraindicated unless there are other specific medical concerns. Choice B reason: Massaging the legs is contraindicated in patients at risk for VTE. If a thrombus is present, massage can dislodge it, potentially leading to a life-threatening pulmonary embolism. Nurses should educate patients to avoid any manipulation of the legs that could mobilize a clot. Choice C reason: Flexing the ankles is a safe and encouraged activity for postoperative patients. It promotes circulation and helps prevent venous stasis. Ankle pumps are often part of early mobility protocols to reduce the risk of VTE. Choice D reason: Ambulating soon after surgery is a key preventive measure against VTE. Early mobilization improves circulation and reduces the risk of clot formation. Unless contraindicated by the patient’s condition, ambulation should be initiated as soon as medically appropriate.
