CHS Blood Pressure Measurement Techniques & Monitoring

Question 1

What is the recommended cuff bladder width for standard adult blood pressure measurement?

Accepted Answer

12–14 cm

Answer

The standard adult BP cuff bladder should be 12–14 cm wide and encircle at least 80% of the arm circumference for accurate readings.

Question 2

Which arm position is recommended for accurate auscultatory blood pressure measurement?

Accepted Answer

Arm supported at heart level (mid-sternum)

Answer

The arm must be supported at heart level because positions lower than the heart falsely elevate readings and positions higher falsely lower them.

Question 3

How long should a patient rest in a seated position before a blood pressure measurement is taken?

Accepted Answer

5 minutes

Answer

AHA/ACC guidelines recommend at least 5 minutes of quiet rest before measurement to allow cardiovascular stabilization.

Question 4

What is the correct rate of cuff deflation during auscultatory blood pressure measurement?

Accepted Answer

1–2 mmHg per second

Answer

Deflating at 1–2 mmHg per second allows accurate identification of each Korotkoff sound phase and prevents over- or underestimation of pressure.

Question 5

Which Korotkoff sound phase corresponds to the systolic blood pressure reading?

Accepted Answer

Phase I

Answer

Phase I is the first appearance of clear, repetitive tapping sounds as blood begins flowing through the compressed artery, marking systolic pressure.
