Answer to Question 1

ANS: C
The goal of selecting a specific fractional inspired oxygen (FIO2) for a patient is to achieve a clin-ically acceptable arterial oxygen tension (e.g., 60-100 mm Hg).

Answer to Question 2

ANS: D
Using a high oxygen concentration following a cardiac arrest can provide a way of restoring normal oxygenation and replacing tissue oxygen storage when oxygen debt and lactic acid ac-cumulations occur, as with this patient.
