An RT Is Taking the Blood Pressure in the Arm

An RT is taking the blood pressure in the arm of a 12-year-old girl. The only sphygmomanometer available has a cuff in which the ends overlap slightly when it is inflated. The pressure that the RT records:

A) should be accurate if the measurement is otherwise done properly.
B) is likely to be in error, showing a value that is too low.
C) is likely to be in error, showing a value that is too high.
D) will have a value that cannot be predicted to be either too high or too low.
