Hypoactive bowel sounds are defined as fewer than how many sounds per minute?

• A. Less than 5
• B. Less than 10
• C. Less than 15
• D. Less than 20

Answer: (A)

The pace of bowel sounds reflects how active the intestines are. When you listen with a stethoscope, you’re counting peristaltic noises per minute. Hypoactive bowel sounds mean the gut isn’t moving much, defined by hearing fewer than five sounds in one minute. Normal motility typically produces a modest series of sounds, roughly in the range of about 5 to 30 per minute, while hyperactive sounds are more frequent and can be loud or tinkling in cases like obstruction early on or gastroenteritis. Clinically, hypoactivity can appear after surgery, with ileus, or when medications slow motility, and recognizing it helps guide further evaluation. To assess, listen in all four quadrants for about a minute per quadrant and compare the overall rate of sounds rather than focusing on a single area.
