A nurse is caring for a client with severe influenza who requires an external source of oxygen in order to breathe efficiently. In which of the following situations is oxygen humidified?
A) When more than 2 L/min of oxygen is administered for an extended period
B) When more than 2 L/min but less than 3 L/min oxygen is administered
C) When more than 4 L/min of oxygen is administered for an extended period
D) When more than 5 L/min of oxygen is administered intermittently
C
Feedback:
When administering oxygen to a client using an external source of oxygen, the nurse should remember that oxygen is humidified when more than 4 L/min of oxygen is administered for an extended period. Oxygen need not be humidified if less than 4 L/min of oxygen has been administered to the client. Oxygen administered over an extended period of time, not intermittently, is humidified.
