Answer to Question 1

ANS: D
Unlike the larger units, some of these systems do not use a couplant compartment; the medication is placed directly into the manifold on top of the transducer. The transducer is connected by ca-ble to a power source, often battery-powered to increase portability. These devices have no blower; the patient's inspiratory flow draws the aerosol from the nebulizer into the lung.

Answer to Question 2

ANS: B
Both theoretical advantages of the ultrasonic devices are outweighed by relatively high purchase costs and poor reliability.
