During a physical examination of an adult client, the nurse is preparing to auscultate the client's abdomen. The nurse should

Auscultation of the abdomen assesses bowel sounds, vascular bruits, and peristaltic activity. Proper technique is essential because abdominal sounds are high-pitched and require appropriate stethoscope use to avoid inaccurate interpretation of gastrointestinal function. Rationale: A. Palpation before auscultation is incorrect. Abdominal examination sequence requires auscultation before palpation or percussion because palpation can stimulate bowel activity and alter baseline bowel sounds, leading to inaccurate assessment findings. B. Using the diaphragm of the stethoscope is correct. High-frequency bowel sounds are best transmitted through the diaphragm, which effectively detects peristalsis and vascular sounds across abdominal quadrants with clarity and accuracy. C. Listening in each quadrant for 15 seconds is insufficient. Standard assessment protocol requires auscultation for at least 30–60 seconds per quadrant, especially if bowel sounds are absent, to ensure accurate evaluation of intestinal activity. D. Beginning in the left upper quadrant is incorrect. Systematic abdominal assessment typically begins in the right lower quadrant to locate the ileocecal valve area where bowel sounds are most consistently heard, then proceeds in a clockwise pattern.
