Correct Answer is A
Explanation
Choice A rationale: The absence of bowel sounds on post-operative day 2 may indicate paralytic ileus, which is a temporary impairment of bowel motility. Paralytic ileus can last for 3-5 days postoperatively and is considered a normal response to surgery.
Choice B rationale: It is not normal for all post-op patients to have absent bowel sounds on day 2. Bowel sounds should typically return within the first 24 hours after surgery.
Choice C rationale: The absence of bowel sounds can be a normal finding in the immediate postoperative period, especially within the first 24 hours. However, it becomes abnormal if prolonged.
Choice D rationale: Documenting absent bowel sounds is appropriate, but notifying the physician should be based on the overall clinical picture and other symptoms.
