Answer to Question 1

ANS: D
As long as mist can be seen escaping throughout inspiration, flow is adequate to meet the pa-tient's needs, and the delivered FiO2 is ensured.

Answer to Question 2

ANS: C
These systems must be equipped with an emergency inlet valve that allows room air breathing in the event of source gas failure.
