A nurse is caring for a client who is postoperative following abdominal surgery. Which of the following findings should indicate to the nurse the client's peristalsis is returning?

Choice A reason: Hypoactive bowel sounds may be present in the early postoperative period but do not confirm the return of effective peristalsis. They can be misleading and are not a reliable indicator of bowel function recovery. Choice B reason: Abdominal distention suggests delayed gastric emptying or accumulation of gas and fluids due to impaired peristalsis. It is a sign of ileus or obstruction rather than recovery. Choice C reason: Passage of flatus is a direct and reliable sign that peristalsis is returning. It indicates that the bowel is moving gas through the intestines, a key milestone in postoperative recovery and readiness for oral intake. Choice D reason: A request for food or drink may reflect improved alertness or comfort but does not confirm gastrointestinal motility. Without objective signs like flatus or bowel sounds, it cannot be used to assess peristalsis.
