Question

Why are cuffs 20% larger than the limb?

a) To ensure a snug fit
b) To account for limb swelling
c) To minimize pressure
d) To reduce cost

Answer 1

The cuffs are 20% larger than the limb to account for limb swelling.

Step-by-step explanation:

The cuffs are 20% larger than the limb to account for limb swelling. When a person's limb swells, the cuff needs to accommodate the increased size without causing discomfort or restricting blood flow. This is particularly important in medical settings, where cuffs are commonly used for blood pressure measurements.

For example, if a patient's arm swells due to an injury or a medical condition, a cuff that is 20% larger than the limb can still be comfortably placed around the arm without causing excessive pressure. This ensures accurate and safe measurement of blood pressure.

Thus, option b) To account for limb swelling is the correct answer.
