Final answer:
The blood pressure cuff should cover about 80% of the patient's upper arm when properly sized.
Step-by-step explanation:
The blood pressure cuff should cover about 80% of the patient's upper arm when properly sized.
Proper sizing of the blood pressure cuff is essential to ensure accurate measurements. If the cuff is too small, it can result in falsely elevated blood pressure readings. If the cuff is too large, it can result in falsely low blood pressure readings.
When measuring blood pressure, the inflatable cuff should be positioned on the upper arm at the same level as the heart. This allows for accurate measurement of blood flow and corresponding pressures.
