The following items consist of two statements, one labeled as “Assertion (A)” and the other labeled as the “Reason (R)”. You are to examine the two statements carefully and decide if the Assertion (A) and the Reason (R) are individually true and if so whether the reason is a correct explanation of the assertion. Select your answer to these items using the codes given below and mark your answer accordingly. Assertion (A): A sphygmomanometer is always used in conjunction with a means to determine at what pressure, blood flow is just starting, and at what pressure it is unimpeded. Reason (R): Manual sphygmomanometers are used in conjunction with a stethoscope.
