What action is recommended when the cuff would sit over thick clothing?

• A. Take the measurement over the clothing anyway
• B. Use a larger cuff over clothing
• C. Move to the other arm
• D. Remove clothing as needed to place cuff directly on bare skin

Answer: (D)

The key idea here is that the blood pressure cuff must be placed directly on bare skin to get an accurate reading. Thick clothing between the cuff and the arm can prevent the cuff from sealing properly and interfere with sensing the artery’s pulsations. This introduces air gaps and fabric compression that distort the pressure measured inside the cuff, often giving unreliable or falsely high readings. So when the cuff would ride over thick clothing, the correct action is to remove the clothing or roll up the sleeve so the cuff sits on bare skin at heart level.

Taking the measurement over clothing is not recommended because it compromises accuracy, and simply using a larger cuff over clothing doesn’t solve the problem since the fabric still interferes with proper occlusion and pressure transmission. Moving to the other arm doesn’t address the issue of clothing either; it’s a separate consideration if there’s a reason to use the other arm.
