Answer to Question 1

Ans: A
The bladder of the cuff should enclose at least two-thirds of the adult limb. If the cuff is too narrow, the reading could be erroneously high because the pressure is not being transmitted evenly to the artery.

Answer to Question 2

Ans: A
The first sound heard through the stethoscope, which is the onset of phase I of Korotkoff sounds, represents the systolic pressure.
