During an abdominal examination, which technique is used to listen to bowel sounds?

• A. Auscultation
• B. Palpation
• C. Percussion
• D. Inspection

Answer: (A)

Listening to bowel sounds is done with auscultation, using a stethoscope placed on the abdomen. This technique specifically checks the movement of gas through the intestines, producing the characteristic gurgles and clicks of peristalsis. It’s different from palpation (touching to feel tenderness, masses, or organ size), percussion (tapping to estimate density or air/fluid in structures), and inspection (visual observation). In an abdominal exam, auscultation is performed before palpation or percussion so that touching or tapping does not alter the bowel sounds. Normal bowel sounds are intermittent, soft gurgles or clicks heard several times per minute; absence or abnormal activity can indicate issues such as ileus or obstruction. This is why auscultation is the best technique for listening to bowel sounds.
