What are Korotkoff sounds?

  • A. Sounds noted during diastole.
  • B. The result of the vibration of blood against artery walls while blood pressure readings are being taken.
  • C. Sounds only noted by skilled cardiologists.
  • D. Distinct sounds which are classified into 6 phases.
Correct Answer: B

Rationale: Korotkoff sounds are the sounds that occur when blood flows in an artery that has been temporarily compressed during a blood pressure measurement. These sounds result from the vibration of blood against the artery walls as the pressure cuff is released. There are five distinct phases of Korotkoff sounds, which healthcare providers are trained to identify during blood pressure assessment. The correct answer, choice B, accurately describes the nature of Korotkoff sounds and how they are generated. Choices A, C, and D are incorrect because Korotkoff sounds are not specific to diastole, not limited to skilled cardiologists, and categorized into five phases, not six.
