Which postoperative intervention should a nurse prioritize for a patient who has undergone a cholecystectomy?

A. Keeping the patient hydrated with oral fluids: While hydration is necessary, the patient's diet usually progresses slowly from clear liquids to solids after abdominal surgery. Oral intake must be balanced with the return of bowel sounds to prevent postoperative ileus. It is not the highest priority for preventing systemic complications. +1 B. Assessing the surgical site for signs of infection hourly: While monitoring the incision is a standard nursing duty, hourly checks are generally unnecessary unless there is active hemorrhage. Infection typically takes several days to manifest and does not pose the most immediate postoperative risk. More frequent monitoring should focus on respiratory and circulatory status. C. Encouraging the patient to eat a full meal immediately: Introducing a full meal too early can cause nausea, vomiting, and gastric distress following general anesthesia. The gastrointestinal tract requires time to resume normal peristalsis after manipulation and pharmacological depression. Diet is traditionally advanced as tolerated rather than forced immediately. D. Ambulation as soon as possible to prevent complications: Early mobility is the most effective intervention for preventing deep vein thrombosis, pulmonary embolism, and pneumonia. It stimulates peristalsis and helps clear anesthetic gases from the system. This priority action significantly reduces the duration of hospital stays and improves recovery.
