Step-by-step explanation:
The nurse will place the highest priority on assisting the patient to ambulate the evening of the operative day. Ambulation, or walking, is important after a surgery like an incisional cholecystectomy as it helps prevent complications such as blood clots and pneumonia. It also promotes circulation and helps the patient regain strength and mobility.
