Answer to Question 1

ANS: A
Individual doses are inhaled as soon as the seal is broken. The high peak inspiratory flow rates (>60 L/min) required to dispense the drug powder from most current DPI designs result in a pharyngeal dose comparable with that received from a typical pressurized metered dose inhaler without an add-on device.

Answer to Question 2

ANS: B
With normal breathing, actuate the pMDI once and have the patient breathe through the device for three to seven breaths (three breaths for adults and seven breaths for infants).
