Answer to Question 1

ANS: D
To achieve the greatest aerosol deposition when using a pMDI or SVN, the device should be placed close to the patient, between the leak port and the face mask.

Answer to Question 2

ANS: D
With VC-CMV, the volume-time scalar will remain constant. The expiratory portion of the flow-time scalar can show improvement if there is a response to the bronchodilator. The changes in PIP can be monitored with the pressure-time scalar and/or the pressure-volume loop.
