a. will be lower if the cuff is too wide.
b. is not affected by cuff length.
c. should be taken slowly for more accuracy.
d. should be taken with the arm above heart level.
A
A bladder or cuff that is too wide will yield false-low readings. A cuff that is wrapped too loose-ly or unevenly will yield false-high readings. Deflating a cuff too slowly will produce false-high diastolic readings. The arm should be at the level of the heart. Having the arm above heart level will produce a false-low reading.
