Tap to reveal answer↕
Answer
A.A falsely high blood pressure reading
B.No effect on the reading, only patient discomfort
C.An accurate reading if inflated slowly
D.A falsely low blood pressure reading
A cuff that is too small requires more pressure to compress the artery, producing a falsely high reading. A cuff that is too large produces a falsely low reading. Cuff size must match the patient's arm circumference for accuracy.
