To evaluate a suspected carotid artery obstruction, which assessment technique is preferred?

Explanation:
Listening for sounds over the carotid arteries with a stethoscope is the preferred first step because it can reveal bruits—turbulent flow caused by narrowing. This noninvasive sign helps indicate significant stenosis and guides further imaging if needed. Measuring the neck or visual assessment don’t provide information about blood flow, and pressing on the carotids (palpation) can be risky if plaque is present, potentially dislodging material and causing an embolic event. So, auscultation for bruits offers the most direct, safe clue to suspect carotid obstruction.
