Answer to Question 1

ANS: C
In either case, it is suggested that O2 levels be titrated down from 100 to 50 O2 in decre-ments not to exceed 20.

Answer to Question 2

ANS: C
For reducing O2 concentration from 50 to 21, O2 changes should be in steps of 5 to 10 followed by oximetry or measurement of blood gases.
