QuestionSBA
QuestionChoice
This is incorrect. When you initially pump the cuff to a pressure above the systolic blood pressure, no sounds are heard as the artery is fully occluded. Korotkoff sounds are only heard when the cuff pressure is between the systolic and diastolic blood pressure as this is the period of turbulent flow.

b
Korotkoff sounds are only heard when the cuff pressure is above the systolic pressure
QuestionChoice
This is incorrect as this is when no sounds are heard. When you initially pump the cuff to a pressure above the systolic blood pressure, no sounds are heard as the artery is fully occluded. Once the cuff pressure is below the systolic but above the diastolic pressure, there is turbulent flow through the artery, giving the characteristic Korotkoff sounds (due to the impact of the blood onto the vessel wall causing vibrations). Once the cuff pressure is below the diastolic pressure, the artery returns to laminar flow so no sounds are heard.

d
Korotkoff sounds are only heard when the cuff pressure is either above the systolic pressure or below the diastolic pressure
QuestionChoice
This is correct. When you initially pump the cuff to a pressure above the systolic blood pressure, no sounds are heard as the artery is fully occluded. Once the cuff pressure is below the systolic but above the diastolic pressure, there is turbulent flow through the artery, giving the characteristic Korotkoff sounds (due to the impact of the blood onto the vessel wall causing vibrations). Once the cuff pressure is below the diastolic pressure, the artery returns to laminar flow and so no sounds are heard.

a
Korotkoff sounds are only heard when the cuff pressure is between the systolic and diastolic pressure
QuestionChoice
This is incorrect. Once the cuff pressure is below the diastolic pressure, there is normal laminar flow through the artery so no sounds are heard. Korotkoff sounds are only heard when the cuff pressure is between the systolic and diastolic blood pressure as this is the period of turbulent flow.

c
Korotkoff sounds are only heard when the cuff pressure is below the diastolic pressure
QuestionChoice
This is incorrect. When you initially pump the cuff to a pressure above the systolic blood pressure, no sounds are heard as the artery is fully occluded. Once the cuff pressure is below the systolic but above the diastolic pressure, there is turbulent flow through the artery, giving the characteristic Korotkoff sounds (due to the impact of the blood onto the vessel wall causing vibrations). Once the cuff pressure is below the diastolic pressure, the artery returns to laminar flow so no sounds are heard.
