When a client needs oxygen therapy, what is the highest flow rate that oxygen can be delivered via nasal cannula?
Correct answer
C
Rationale
The correct answer is 6 liters/minute. When a client needs oxygen therapy, the highest flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Higher flow rates must be delivered by a mask. Choices A, B, and D are incorrect because they suggest flow rates that exceed what can be effectively delivered through a nasal cannula.
