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. "Place a pillow under your knees while in bed.": Elevating the knees with a pillow can compress blood vessels and restrict circulation, increasing the risk of venous stasis and deep vein thrombosis. B. "Participate in range-of-motion exercises.": Performing range-of-motion exercises promotes blood flow in the extremities, prevents venous stasis, and reduces the risk of complications such as deep vein thrombosis, supporting postoperative circulation. C. "Remain on bed rest for 24 hours following the procedure.": Prolonged immobility can impair circulation and increase the risk of blood clots. Early ambulation and movement are encouraged unless contraindicated by the provider. D. "Use an incentive spirometer every hour”: While using an incentive spirometer is important for preventing respiratory complications, it primarily promotes lung expansion and does not directly enhance circulation.
