A patient using a non-rebreather mask has a reservoir bag that collapses completely during inspiration. Which action should the nurse take?
Correct answer: B. Increase the oxygen flow so the reservoir stays partly inflated
- A. Reduce the oxygen flow until the bag remains empty
- B. Increase the oxygen flow so the reservoir stays partly inflated
- C. Remove the mask and place the patient on room air
- D. Cover the exhalation ports to prevent oxygen loss
Explanation
The reservoir bag should remain partially inflated during inspiration so the patient can receive the prescribed high oxygen concentration. A collapsing bag suggests inadequate flow or a system problem, while covering the ports can cause carbon dioxide rebreathing.

About Oxygen Therapy and Airway Care
Airway care includes positioning, suctioning, coughing and deep-breathing exercises, incentive spirometry, oxygen delivery devices and humidification. Questions address indications, flow rates, safety precautions and monitoring for hypoxia or oxygen toxicity, while distinguishing nasal cannula, simple mask, non-rebreather mask and Venturi mask use.
