Answer to Question 1

ANS: D
Although flow savings are fairly predictable, factors such as nasal anatomy and breathing pattern can affect the performance of the device.

Answer to Question 2

ANS: C
Table 41-3 outlines the FiO2 range, FiO2 stability, advantages, disadvantages, and best use of oxygen delivery devices. Based on these guidelines, the nasal cannula appears most suitable for this patient.
