Which option correctly identifies the proper technique for measuring blood pressure?

• A. Take the measurement with the patient standing and the arm unsupported.
• B. Use an appropriately sized cuff, patient seated with back supported, arm at heart level, no talking, and proper cuff inflation/deflation rate.
• C. Inflate the cuff to the maximum and quickly read the systolic value.
• D. Have the patient talk during the measurement to ensure responsiveness.

Answer: (B)

Accurate blood pressure measurement depends on proper positioning, an appropriate cuff, and a controlled technique. When the patient is seated with the back supported and the arm resting at heart level, posture won’t skew the reading and muscle tension stays low. A cuff that fits the arm well ensures the pressure you measure reflects the true arterial pressure rather than an over- or under-tight cuff. Staying quiet during the measurement prevents interference from talking or anxiety, which can artificially raise readings. Inflation should be enough to occlude the artery, and deflation should be slow and steady so you can clearly hear the Korotkoff sounds to identify systolic and diastolic values. Altogether, these elements produce a reliable, reproducible reading. Using a standing posture with an unsupported arm, inflating to the maximum and reading quickly, or having the patient talk during the measurement all introduce errors or noise that compromise accuracy.
