A nurse is providing preoperative teaching to a client about promoting circulation during the postoperative period. Which of the following instructions should the nurse include?

Rationale: A. Use an incentive spirometer every 4 hours: Incentive spirometry is primarily used to promote lung expansion and prevent atelectasis postoperatively. While important, it is aimed at respiratory function, not directly at promoting circulation. B. Remain on bed rest for 24 hours following the procedure: Prolonged bed rest can lead to venous stasis and increase the risk of thromboembolic events. Early ambulation or movement is encouraged to improve circulation and prevent complications like deep vein thrombosis (DVT). C. Place a pillow under your knees while in bed: Placing a pillow under the knees can cause venous stasis by compressing the popliteal vessels and should be avoided. It may also contribute to joint stiffness and increase the risk of DVT. D. Participate in range of motion exercises: Range of motion exercises encourage venous return and stimulate blood flow in the extremities. This helps prevent postoperative complications such as DVT and promotes overall circulatory health.
