Answer to Question 1

ANS: C
Vibrating mesh nebulizers add no gas to the aerosol stream. They can generate aerosol from a single drop of liquid, so they require very little solution to produce an aerosol. The exit velocity of the aerosol is slow (less than 4 m/s), and the particle can range from 2 to 5 m (mass median aerodynamic diameter).

Answer to Question 2

ANS: B
Filling the nebulizer with 5 mL would make 3.5 mL, or 70 of the medication, available for neb-ulization.
