Question

An appropriate sized blood cuff should:

Select one:
a. cover at least one third of the patient's upper arm.
b. be one half to two thirds the size of the upper arm.
c. completely encompass the entire upper arm.
d. cover at least two thirds of the patient's upper arm

Answer 1

The right size for a blood pressure cuff is one that covers one half to two thirds the size of the upper arm, ensuring accurate blood pressure measurement. The correct answer is option b.

Step-by-step explanation:

An appropriate sized blood pressure cuff should be one half to two thirds the size of the upper arm. This means the correct answer to the question is 'be one half to two thirds the size of the upper arm.' Using a cuff of the correct size is essential for accurate measurement of blood pressure. If the cuff is too small, it may yield a measurement that is higher than the actual blood pressure.



Conversely, if the cuff is too large, the measurement may be falsely low. The cuff should be wrapped tightly around the patient's arm, at the same level as the heart. As air is injected into the cuff, it should create enough pressure around the artery to temporarily cut off blood flow, allowing for an accurate measurement when the pressure is gradually released.
