Answer to Question 1

ANS: D
The VORTRAN-IPPB device provides short-term, pressure-triggered, pressure-cycled, con-stant-flow ventilatory support in combination with aerosol therapy. The primary advantage of these devices is that they are relatively compact and inexpensive compared with conventional intermittent positive-pressure breathing devices. In addition, the VORTRAN-IPPB units are sin-gle-patient, multiple-use devices, a situation that reduces the incidence of nosocomial infections caused by cross-contamination.

Answer to Question 2

ANS: C
Patients should be instructed to inspire through the one-way valve of the positive expiratory pressure device to a volume that is greater than the normal tidal volumebut not to the total lung capacity. At the end of inspiration, patients are encouraged to actively, but not forcefully, exhale to functional residual capacity.
