Answer to Question 1

ANS: D
Estimating the FiO2 provided by low-flow systems: For patients with a normal rate and depth of breathing, each liter per minute of nasal O2 increases the FiO2 approximately 4. For example, a patient using a nasal cannula at 4 L/min has an estimated FiO2 of approximately 37 (21 + 16).

Answer to Question 2

ANS: D
Proper device selection requires in-depth knowledge of both the general performance characteris-tics of these systems and the individual capabilities.
