Which of the following are true about a solution that is being aerosolized by an ultrasonic nebu-lizer?
 
  1. The solute concentration decreases.
  2. The temperature of the solution increases.
  3. The solute concentration increases.
  4. The temperature of the solution decreases.
  a. 1 and 2 only
  b. 2 and 3 only
  c. 2 and 4 only
  d. 3 and 4 only

Question 2

What is the average mean mass aerodynamic diameter (MMAD) generated by the vibrating mesh nebulizers?
 
  a. 1 to 2 m
  b. 2 to 3 m
  c. 3 to 4 m
  d. 5 to 6 m

Answer to Question 1

ANS: B
As the temperature increases, the drug concentration increases, as does the likelihood of unde-sired side effects.

Answer to Question 2

ANS: B
The exit velocity of the aerosol is low, less than 4 m/sec, and the particle size can range between 2 and 3 m MMAD, varying with the exit diameter of the apertures (Figure 39-27).
