Answer to Question 1

ANS: C
A patient with asthma benefits from a precise preset FIO2. With a simple mask, there is a greater likelihood of the patient retaining CO2, which is not helpful for those with asthma. Breathing through pursed lips is beneficial to people with asthma; however, it is not the first course of ac-tion. Finally, a high-flow cannula at 15 L/min is too much FIO2 for the patient at this time.

Answer to Question 2

a. blender
