Answer to Question 1

ANS: C
Most aerosols found in nature and used in respiratory care are composed of particles of different sizes, described as heterodisperse.

Answer to Question 2

ANS: C
Because medical aerosols contain particles of many different sizes (are heterodisperse), the aver-age particle size is expressed with a measure of central tendency, such as MMAD for cascade impaction or volume median diameter (VMD) for laser diffraction.
