Which statement is true about cuff sizing for BP measurement in obese patients?

• A. Pediatric cuff
• B. Standard cuff
• C. Thigh cuff
• D. Use large cuff encircling 80% of the arm

Answer: (D)

Accurate blood pressure relies on a cuff that fits the arm properly. The bladder should encircle about 80% of the arm circumference, with a width about 40% of that circumference. In obese patients, the arm is larger, so using a large adult cuff that encircles 80% of the arm ensures the cuff is wide enough and long enough to compress the artery evenly. A pediatric cuff is too small for an adult arm, which can falsely elevate readings; a standard cuff may be too narrow for a large arm; and a thigh cuff is designed for a different limb and can distort results when used on the upper arm. Therefore, using a large cuff that encircles about 80% of the arm is the best practice for accurate measurement in obese patients.
