Which feature distinguishes a simple face mask from a non-rebreather mask?
Correct answer: C. The simple mask has no reservoir bag or one-way valves
- A. The simple mask has a reservoir bag and one-way valves
- B. The simple mask can deliver the highest oxygen concentration
- C. The simple mask has no reservoir bag or one-way valves
- D. The simple mask is used only with mechanical ventilation
Explanation
A simple face mask delivers oxygen through the mask without a reservoir bag and one-way valve system. The non-rebreather mask uses these features to reduce rebreathing and provide a higher oxygen concentration.

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.
