Which action gives the most accurate manual blood pressure measurement in an adult?
Correct answer: C. Support the bare arm at heart level before inflating the cuff
- A. Place the cuff over a thick sleeve with the arm hanging down
- B. Use a cuff that covers half of the upper-arm circumference
- C. Support the bare arm at heart level before inflating the cuff
- D. Ask the patient to talk normally while the pressure is released
Explanation
The bare arm should be supported at heart level, with an appropriately sized cuff and the patient resting quietly. A hanging arm, clothing under the cuff, talking, or an incorrect cuff size can produce an inaccurate reading.
