Hyperactive bowel sounds are defined as more than how many sounds per minute?

• A. Greater than 20
• B. Greater than 25
• C. Greater than 28
• D. Greater than 30

Answer: (D)

Bowel sounds reflect how active the intestines are. To decide if sounds are hyperactive, you count how many jetting peristaltic noises you hear in a minute. A common cutoff used in practice is more than 30 sounds per minute—that rate indicates hyperactive bowel sounds. To assess, auscultate in all quadrants with the diaphragm and listen for a full 60 seconds, counting each peristaltic sound. Normal motility falls short of this rate, so hearing more than 30 per minute points to increased intestinal activity. This can occur with conditions like gastroenteritis or other causes of increased motility. The other lower thresholds would underestimate hyperactivity, which is why the cutoff above 30 per minute is the best choice.
