A patient receiving oxygen through a simple face mask has an oxygen flow rate of 3 L per minute. What should the nurse do?
Correct answer: A. Increase the flow to at least 5 L per minute
- A. Increase the flow to at least 5 L per minute
- B. Change immediately to a non-rebreather mask
- C. Remove the mask and use room air
- D. Place a paper bag over the mask
Explanation
A simple face mask generally requires a minimum flow of about 5 L per minute to prevent rebreathing exhaled carbon dioxide. A flow of 3 L per minute is inadequate and may cause carbon dioxide retention within the mask.
