Multiple Choice Question

When measuring blood pressure, if the sphygmomanometer cuff bladder is too narrow for the patient's arm circumference, how will it affect the reading?

A

Inability to palpate brachial pulse
B

Falsely decreased (low) reading
C

Falsely elevated (high) reading

No change in systolic pressure

Explanation:

A cuff that is too small or narrow produces a falsely high BP reading because extra cuff pressure is needed to occlude the brachial artery. A cuff that is too large gives falsely low readings.
