Answer to Question 1

ANS: C
Ultrasonic nebulizers are valued clinical tools for inducing sputum production so that specimens can be used for diagnostic analysis. Ultrasonic nebulizers yield a higher quantity and quality of sputum specimens for analysis than other nebulizers but at some cost of increased airway reactiv-ity.

Answer to Question 2

ANS: D
Larger versions of these devices (with 2- to 3-L reservoirs) are used to deliver bland aerosols into mist tents. These enclosure systems can generate flow rates greater than 20 L/min, with water outputs as high as 5 mL/min (300 mL/hr). Because heat buildup in enclosures is a problem, these systems are always unheated.
