Nursing Acceleration Challenge Exam (NACE) PN-RN Practice Test

How long should the nurse auscultate for bowel sounds before determining that they are absent?

1. 3 to 5 minutes

2. 2 to 3 minutes

3. 1 to 2 minutes

4. 30 to 60 seconds

The correct answer is: 3 to 5 minutes

Auscultating for bowel sounds is an important part of the abdominal assessment in nursing practice. When evaluating bowel sounds, it is crucial for the nurse to listen for a sufficient amount of time before concluding that they are absent. The standard duration for this assessment is typically considered to be 3 to 5 minutes. This time frame allows the nurse to effectively assess the presence or absence of bowel sounds, which can vary significantly among individuals and may require a longer listening period, especially if bowel activity is reduced. If the nurse were to listen for less time, they might mistakenly conclude that bowel sounds are absent when, in fact, they are simply faint or intermittent. Listening for a full 3 to 5 minutes ensures a more accurate evaluation and aids in diagnosing conditions such as ileus or bowel obstruction, where the absence of bowel sounds could indicate a serious underlying issue.
