What happens when blood pressure is measured too quickly with the cuff?

• A. The reading is too low
• B. The reading is too high
• C. The reading remains accurate
• D. No significant change

Answer: (B)

When blood pressure is measured too quickly with the cuff, the reading may be too high. This occurs because rapid deflation of the cuff can lead to an inaccurate estimation of the systolic pressure. When the cuff pressure is released quickly, it might not allow sufficient time for the blood flow to stabilize, which can cause a spike in the readings.

Additionally, if the cuff is deflated too rapidly, the sound of the Korotkoff sounds may not be distinct or may not reflect the true point of blood flow resumption, leading to a falsely elevated reading. It's important to deflate the cuff slowly to accurately capture the transition from systolic to diastolic pressure, ensuring the readings reflect true hemodynamics.
