What is the standard sequence for clinic blood pressure measurements?

• A. Take one reading after activity, then average with previous visits.
• B. Ensure rest, measure twice (or more) in the same arm, wait 1-2 minutes between readings, discard the first if abnormal, and use the average of the last two readings.
• C. Measure in both arms simultaneously, take the higher value.
• D. Rest for 10 minutes and then take a single reading in the arm with IV.

Answer: (B)

In clinic blood pressure measurement, accuracy comes from a calm, standardized procedure. Have the patient seated with back supported and feet uncrossed, the arm supported at heart level, and a properly sized cuff placed on the bare upper arm. Ensure the patient rests quietly for several minutes before taking readings. Take measurements in the same arm, doing at least two readings with a 1–2 minute interval between them. If the first reading is unreliable or notably high, discard it and rely on the average of the last two readings. This sequence reduces the influence of recent activity, anxiety, or cuff placement and gives a more reproducible estimate of true blood pressure. The other approaches—measuring after activity or using multiple arms simultaneously or a single reading after a long rest with an IV in the arm—do not align with standard practice and can distort the result.
