Which term refers specifically to a vascular sound caused by turbulent blood flow in arteries due to plaque or vessel damage?

• A. Bruit
• B. Carotid bruit
• C. Murmur
• D. NSR

Answer: (B)

The key idea is a vascular sound produced by turbulent flow from narrowed or damaged vessels. A bruit is the general term for such sounds. When this turbulence is heard specifically over the carotid artery in the neck—often from atherosclerotic plaque narrowing the artery—the sound is called a carotid bruit. This distinguishes it from a heart murmur, which originates from turbulent flow across heart valves, and from NSR, which is a normal rhythm with no abnormal vascular sound. Carotid bruits flag potential carotid artery stenosis and stroke risk, so recognizing the term that ties the sound to the carotid artery is why this choice is best.
