Yes

Your answer is correct! Korotkoff sounds are indeed related to the determination of blood pressure. These sounds are created by turbulent blood flow through constricted arteries when a blood pressure cuff is slowly deflated. These sounds are commonly used to measure blood pressure during a physical examination. Well done!
