Which oxygen delivery system would the nurse apply that would provide the highest concentrations of oxygen to the client?
- A. Venturi mask
- B. Partial rebreather mask
- C. Non-rebreather mask
- D. Simple face mask
Correct Answer: C
Rationale: Non-rebreather mask. The non-rebreather mask has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent inhalation of room air but to allow exhalation of air. When a tight seal is achieved around the mask up to 100% of the oxygen is available.
