C - 5 to 8 L/min is the correct answer.
The simple face mask can provide 40 - 60% of FiO2 at a flow rate of 5 - 8L/min
The simple face mask can deliver higher flow rates of oxygen than the nasal cannula.

The mask is made for patients that can breathe on their own, but who may require a higher level of oxygen concentration than the 21% concentration found in ambient air. Examples are patients with emphysema, heart attacks and dizziness.

5 to 8 l/min-simple face masks - for increased flow rates. provide 40 to 60% fio2 at a flow rate of 5 to 8 l/min. minimum flow rate is 5l/min to ensure flushing of co2 from the mask -advantages: more comfortable than nasal cannulas for administration of higher amounts of oxygen. -disadvantages: can be uncomfortable for clients because they must fit snuggly against the face. eating, drinking, and talking are impaired. can be frightening, especially for the client with a history of claustrophobia. if flow rates are not adequate, rebreathing of carbon dioxide can become an issue. p. 31
