The nurse aide has been asked to check oxygen saturation of a client. In order to perform this task, the nurse aide will:

Rationale

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

The pulse oximeter is designed to assess oxygen saturation levels accurately by being placed on a peripheral site, typically the fingertip. This method provides a direct measurement of the client's blood oxygen levels, which is crucial for monitoring respiratory function.

A (scan the infrared light over the client's wrist to read the radial pulse measurement.) YOUR ANSWER

This choice incorrectly suggests using an infrared light for measuring pulse rate at the wrist, which is not the function of a pulse oximeter. Pulse oximeters are specifically designed to measure oxygen saturation through light absorption in blood vessels, not for reading pulse measurements.

B (disinfect the client's earlobe with alcohol, then apply the oximeter, and record the measurement.) YOUR ANSWER

While applying the oximeter to an earlobe is possible, it is less effective than using a fingertip, which is the preferred site for accurate readings. This choice also unnecessarily includes the step of disinfecting the earlobe, which is not standard practice for pulse oximetry.

D (reposition the client if the reading is below 95% and then retake the measurement.) YOUR ANSWER

This option addresses a potential action after obtaining a reading but does not describe the initial step of measuring oxygen saturation. It assumes the measurement has already been taken via an unspecified method, which is not the correct approach to start the assessment.

Conclusion

The accurate method for checking a client's oxygen saturation involves applying the pulse oximeter to the fingertip, as this location provides reliable readings. Other options either misrepresent the device's function, suggest less effective application sites, or refer to actions that come after the initial measurement, thereby failing to address the correct procedure. Proper use of a pulse oximeter is essential for effective patient monitoring in healthcare settings.
