Certified Clinical Medical Assistant CCMA Practice Test

Question: 1 / 400

An MA is reinforcing teaching with a patient about pulse oximetry. Which of the following statements should the assistant include in the teaching?

Avoid eating before the test

Remove your nail polish before the test

The statement about removing nail polish before the test is correct because nail polish can interfere with the accurate readings of a pulse oximeter. The device uses light to measure the oxygen saturation levels in the blood, and nail polish can obstruct the light needed for this assessment, potentially leading to false readings. To ensure the test results are as accurate as possible, it's important for the patient to remove any nail polish or artificial nails prior to the procedure.

In contrast, the other statements do not correctly address critical factors relevant to pulse oximetry. Eating before the test generally does not impact its accuracy; wearing tight clothing does not influence the results; and while deep breathing can be beneficial for comfort, it is not a necessary requirement for obtaining a pulse oximetry reading.
