3. Which one or more of the following devices is NOT used in combination with metered dose inhaler (MDI) therapy to reduce the need for hand-breathing coordination and oropharyngeal impaction of aerosolized drugs?

ANS:  D

Reservoir devices, including both holding chambers with one-way inspiratory valves and simple, nonvalved spacer devices, are often added to an MDI to reduce the need for complex hand-breathing coordination and to reduce oropharyngeal impaction of the aerosol drug.

4. Which of the following is NOT an advantage for the treatment of the respiratory tract with inhaled aerosols?

ANS:  C

The advantages for treatment of the respiratory tract with inhaled aerosols are as follows:

• Aerosol doses are usually smaller than doses for systemic administration.
• Onset of drug action is rapid.
• Delivery is targeted to the organ requiring treatment.
• Systemic side effects are often fewer and less severe.
