Which method is most appropriate to assess for partial obstruction of the carotid artery?

• A. Measuring the neck
• B. Palpating the neck
• C. Auscultating the neck
• D. Visual inspection of the neck

Answer: (C)

Listening with a stethoscope over the neck to hear for bruits is the best way to detect a partial carotid obstruction. Narrowing of the artery causes turbulent blood flow, which creates a distinct whooshing sound called a bruit. This audible sign helps identify stenosis even when there are no obvious external clues, guiding further imaging if needed. Other methods like measuring the neck, visual inspection, or palpation don’t assess blood flow and are less reliable for spotting internal narrowing. Thus, auscultation for bruits directly targets the vascular turbulence that indicates partial obstruction.
