When measuring blood pressure by the auscultatory method.

The sounds that are heard are generated in the heart.
The cuff pressure at which the first sounds are heard indicate systolic pressure.
The cuff pressure at which the loudest sounds are heard indicate diastolic pressure.
Systolic pressure estimations tend to be lower than those made by the palpatory method.
Wider cuffs are required for larger arms.

A. False Korotkoff sounds are produced locally by the turbulence of blood being forced past the narrow segment of a partially occluded artery.

B. True The sharp taps of Phase 1 are generated as the systolic pressure peaks force blood under the cuff.

C. False Sudden muffling (Phase 4) or disappearance (Phase 5) of the sounds indicate the diastolic pressure point.

D. False They are usually higher since palpation may fail to detect the first tiny pulses.

E. True Otherwise the full cuff pressure may not be transmitted to the artery.
