A nurse is providing education to a new graduate nurse regarding the correct application and use of a simple face mask for a client with a respiratory rate of 24/min and an oxygen saturation of 89%. Which of the following statements by the new graduate nurse indicates an understanding of the procedure?

I should clean the face mask with soap and water once per shift.

I should place the mask over the bridge of the nose first and then cover the mouth.

The mask should be positioned to cover only the mouth to allow for nasal expiration.

I can adjust the oxygen flow rate independently if the client's saturation does not improve.
