A nurse is caring for a client who has dyspnea with an oxygen saturation of 88%. Which of the following indicates the type of face mask the nurse should use to deliver the client a 90% oxygen concentration?
Simple face mask
Nasal prongs
Non-rebreather mask
Nasal cannula
The Correct Answer is C
A. Simple face mask: This can deliver oxygen at flow rates of 5-10 liters per minute and typically provides an oxygen concentration of about 35-50%.
B. Nasal prongs: Nasal prongs deliver oxygen at lower flow rates and may not be sufficient to raise the client's oxygen saturation to 90%.
C. Non-rebreather mask: This mask can deliver high concentrations of oxygen (up to 90-100%) at flow rates of 10-15 liters per minute. It has one-way valves to prevent the patient from rebreathing exhaled air, thus maximizing the delivery of oxygen.
D. Nasal cannula: Nasal cannulas deliver oxygen at lower flow rates (typically up to 6 liters per minute) and may not provide the necessary concentration to achieve an oxygen saturation of 90%.
