How can a nurse accurately assess for a post-operative ileus?

• A. By checking for fever and swelling
• B. By checking for bowel sounds and the passage of gas
• C. By reviewing the patient's diet
• D. By monitoring vital signs

Answer: (B)

To accurately assess for a post-operative ileus, checking for bowel sounds and the passage of gas is essential. An ileus is characterized by a temporary cessation of bowel activity, and one of the key indicators of bowel function returning is the presence of bowel sounds. These sounds indicate that peristalsis— the wave-like contractions that move contents through the intestines— is occurring.

Additionally, the passage of gas is a very practical sign that bowel function is returning. When a patient begins to pass gas, it generally suggests that the intestines are starting to recover from the effects of surgery and anesthesia, which commonly lead to temporary disruption in normal bowel motility. Lack of bowel sounds and absence of gas can indicate that an ileus is present, thus warranting further assessment and potential intervention.

Other options do not directly assess for an ileus. Checking for fever and swelling might indicate infection or inflammation but does not provide specific information regarding bowel activity. Reviewing the patient's diet does not assess the current intestinal function and only indicates what the patient can tolerate or has consumed. Monitoring vital signs is important for overall patient assessment but does not give direct insight into the status of bowel motility or the presence of an ileus.
