Answer to Question 1

ANS: B
The spring-loaded valve and the magnetic valve are the only valves that are able to be used dur-ing patient transport. The water column would be subject to leaks and possible breakage of the cylinder. The weighted ball must always be held upright and is impractical for transport.

Answer to Question 2

ANS: C
The purpose of a mechanical insufflation-exsufflation device is to replace or augment cough clearance in individuals with respiratory muscle weakness or paralysis (e.g., neuromuscular dis-ease).
