Answer to Question 1

ANS: D
The output for the 30 air-entrainment mask set at 8 L/min is 72 L/min, because 30 has nine total parts multiplied by 8 L/min, which equals 72 L/min. The total output for 40 should, therefore, be 72 L/min. There are four total parts in 40 multiplied by an unknown flow that equals 72 L/min. 4X = 72. X is equal to 18 L/min.

Answer to Question 2

ANS: D
Without the transtracheal catheter in place, this patient is not receiving any supplemental oxygen. To avoid hypoxemia, the patient must use a back-up delivery device. The most appropriate device in this situation would be a nasal cannula. The patient must call the physician for follow-up im-mediately.
