Answer to Question 1

ANS: D
Studies indicate that mustache and pendant systems may reduce oxygen supply use by 50. Many patients feel that mustache cannulas are heavier, larger, and more obvious. Pendant cannu-las can be concealed by the patient's clothing.

Answer to Question 2

ANS: C
Oxygen is considered a type of medication. If a patient is exposed to large amounts for a long period of time, all of the aforementioned can occur except for chronic obstructive pulmonary disease, which is considered a disease process not a complication.
