Oxygen saturation Measurement
Oxygen saturation Measurement ( 5 Questions)
A nurse is assessing a client's oxygen saturation level. What is the most common method used to measure oxygen saturation?
Arterial blood gas analysis provides more comprehensive information about the client's oxygenation status but is an invasive procedure that requires drawing arterial blood.
Capnography monitoring measures the level of carbon dioxide in exhaled breath and does not directly measure oxygen saturation.
Pulse oximetry is the most common method used to measure oxygen saturation noninvasively. It involves using a pulse oximeter, which uses light to measure the oxygen saturation level of arterial blood.
Spirometry testing measures lung function, such as lung volume and airflow, but does not directly measure oxygen saturation.
Answer: c. Pulse oximetry
Explanation: Pulse oximetry is the most common method used to measure oxygen saturation noninvasively. It involves using a pulse oximeter, which uses light to measure the oxygen saturation level of arterial blood.
