Answer to Question 1

ANS: D
Administering high levels of supplemental O2 can cause lung injury as a result of O2 toxicity. Oxygen toxicity is considered to be time and dose dependent, that is, the longer the exposure and the higher the FiO2, the worse the injury. The RT must continuously titrate the FiO2 and PEEP to keep the target SpO2 in the range of 88 to 95.

Answer to Question 2

ANS: B
The changes in the lung tissue in ARDS are typically separated into two phases based on the overall duration of the disease process: (a) the exudative phase (1 to 7 days) and (b) the fibropro-liferative phase (3 days to weeks).
