A male client who is anxious and fearful removed his rebreather face mask. The mask now needs to be reapplied. Which action should the practical nurse (PN) take first?

A. Request that a respiratory therapist come to the room: While a respiratory therapist can assist, the immediate need is to ensure the client receives oxygen. Delaying to call for help does not address the urgent requirement for oxygen delivery. B. Secure the straps around each of the client's ears: Straps should be secured after properly positioning the mask. Securing straps first may result in improper fit and ineffective oxygen delivery. C. Place mask over the bridge of the nose and then the mouth: Correct placement of the mask over the nose and mouth is the first priority to ensure an adequate oxygen seal and effective therapy. Proper positioning allows oxygen to be delivered safely before checking other components. D. Check that the reservoir bag inflates during exhalation: Observing the reservoir bag is important to verify oxygen flow, but it cannot be done effectively until the mask is correctly positioned on the client’s face.
