1. An oxygen blender is being used to deliver 40% oxygen through a jet nebulizer for humidification to a child. How should a respiratory therapist set the jet nebulizer in this situation?
The jet nebulizer must be set to the 100% setting.
The jet nebulizer must be set at the same FIO2 as the blender.
Setting the jet nebulizer at a FIO2 of 0.40 or less is acceptable
The jet nebulizer can be adjusted to an FIO2 setting greater than 0.70.

3. A physician has ordered an FIO2 of 0
A physician has ordered an FIO2 of 0.40 by oxyhood and blender for an infant. When analyzing the oxygen concentration, a respiratory therapist notes the FIO2 is 0.30, and the flowmeter is set at 10 L/min. The nebulizer’s entrainment port is set at 50% and the blender is set at an FIO2 of To correct the problem, the therapist should:
Increase the flowmeter to 12 L/min
Set the blender FIO2 to 1.0
Replace the blender and nebulizer system
Set the nebulizer’s entrainment port to 100%
