Question

When using the Auscultatory (Indirect) Method to record a patient's blood pressure, there is no audible sound when:

A. the cuff pressure is less than the Diastolic Blood Pressure in an artery

B. the cuff pressure exceeds the Systolic Blood Pressure in an artery

C. both when cuff pressure exceeds the Systolic BP AND when the cuff pressure is less than the Diatolic BP

D. there is always an audible sound present

Answer 1

Answer -C. both when cuff pressure exceeds the Systolic BP AND when the cuff pressure is less than the Diatolic BP

The heart sound can be audible when the cuff pressure lies between systolic blood pressure and diastolic blood pressure, this is due to the collapsing the underlying artery and reopening again. Thus when cuff pressure becomes high, no sound can be audible. The sound which is synchronous with the heart beat ,can be heard properly by ausculatory method when cuff pressure is lower in comparison to the level of systolic pressure.
