Question 5

Apply the pulse oximeter to the client's fingertip and record the measurement.

The nurse aide will apply the pulse oximeter to the client's fingertip to accurately measure oxygen saturation levels. This method is standard practice for non-invasive monitoring of oxygen saturation.

A) Scan the infrared light over the client's wrist to read the radial pulse measurement.

This option is incorrect because measuring oxygen saturation involves using a pulse oximeter, which is typically applied to a fingertip, earlobe, or toe, not the wrist. Additionally, reading the radial pulse does not provide information about oxygen saturation.

B) Disinfect the client's earlobe with alcohol, then apply the oximeter, and record the measurement.

While this procedure would yield a valid method for measuring oxygen saturation, it is not the most common practice. The fingertip is generally preferred for applying a pulse oximeter due to ease of access and comfort for the client.

C) Apply the pulse oximeter to the client's fingertip and record the measurement.

This is the correct choice as applying the pulse oximeter to the fingertip is the most common and effective method for checking oxygen saturation. The fingertip generally provides a reliable reading and is easy to access.

D) Reposition the client if the reading is below 95% and then retake the measurement.

This option, while addressing a potential action to take if oxygen saturation is low, does not answer the question of how to check the oxygen saturation. It assumes a reading has already been obtained without specifying the initial method used to measure it.

Conclusion

The correct answer, applying the pulse oximeter to the client's fingertip, is the standard procedure for measuring oxygen saturation. Other options either suggest incorrect methods or do not directly address the initial action of measuring oxygen saturation. Hence, option C is the most accurate and appropriate response to the task at hand.
