After abdominal surgery with bowel manipulation, what is the expected bowel sound status in the first 24-48 hours?

• A. Absent bowel sounds
• B. Hyperactive bowel sounds
• C. Hypoactive but present
• D. Normal bowel sounds

Answer: (A)

Postoperative ileus is the main idea here. After abdominal surgery with bowel manipulation, the bowel’s motility is temporarily slowed or stopped as part of the normal healing response, anesthesia effects, and opioid pain control. In the first 24 to 48 hours, this suppression of peristalsis commonly results in absent bowel sounds on auscultation because little or no forward movement of gas and fluid is occurring. This absence reflects a transient lack of bowel activity rather than a mechanical blockage. Hyperactive sounds would suggest increased motility, which isn’t expected in this early post-op period. Normal bowel sounds would indicate that motility has returned, which typically hasn’t yet occurred. A hypoactive but present pattern can occur, but absent sounds align best with the expected postoperative ileus in this time frame. Management focuses on supporting the return of motility (gentle advancement of diet as tolerated, minimizing opioids, mobilization, and decompressing the GI tract if distension occurs) while monitoring for resolution of ileus.
