COPE Health Scholars Practice Test

When taking the patient's vital signs, what should be done to the pulse ox?

1. Position it at the wrist

2. Place it on the opposite arm as the blood pressure monitor

3. Turn it off after use

4. Secure it on the leg

The correct answer is: Place it on the opposite arm as the blood pressure monitor

Placing the pulse oximeter on the opposite arm from where the blood pressure monitor is located is important to ensure accurate readings. When vital signs are measured, especially blood pressure and pulse oximetry, performing these assessments on different limbs minimizes the risk of interference from the blood pressure cuff, which can temporarily affect circulation and skew the oximeter’s readings. This practice allows for distinctive and precise measurements, ensuring that the healthcare provider can obtain reliable data for patient assessment. Correct usage of the pulse oximeter facilitates effective monitoring of peripheral oxygen saturation, which is crucial for evaluating the patient’s respiratory function. Utilizing different sites for measuring blood pressure and oxygen saturation enhances the overall reliability of vital sign assessment in a clinical setting.
