Question

multiple choice question
what are korotkoff sounds?
sounds caused by the flow of blood past plaque accumulations in arteries
sounds generated by the closure of metarterioles within the capillary bed
sounds generated during the relaxation phase of the cardiac cycle
sounds of turbulent blood flow heard when taking blood pressure measurements

Explanation:

Korotkoff sounds are produced by turbulent blood - flow when measuring blood pressure. As the pressure in a blood - pressure cuff is gradually released, these sounds can be heard through a stethoscope. They are not related to plaque in arteries, closure of metarterioles, or sounds during the relaxation phase of the cardiac cycle.

Answer:

Sounds of turbulent blood flow heard when taking blood pressure measurements
