Small cuff size will lead to?: (A) Falsely increased BP, (B) Falsely low BP, (C) No effect on BP, (D) Fluctuating BP
Answer is A. a. Falsely increased BP(Ref: Nelson's 20/e p 2164)In older children, a mercury sphygmomanometer with a cuff that covers approximately two-thirds of the upper part of the arm or leg may be used for blood pressure measurement. A cuff that is too small results in falsely high readings, whereas a cuff that is too large records slightly decreased pressure.
