Answer to Question 1

ANS: C
The high percentage of oropharyngeal drug deposition with use of steroid pressurized MDIs (pMDIs) can increase the incidence of opportunistic oral yeast infection (thrush) and changes in the voice (dysphonia). Rinsing the mouth after steroid use can help avoid this problem, but most pMDI steroid aerosol impaction occurs deep in the hypopharynx, which cannot be easily rinsed with gargling. For this reason, steroid pMDIs should not be used alone but always in combination with a spacer or valved holding chamber.

Answer to Question 2

ANS: C
Patients experiencing an acute exacerbation of bronchospasm may not be able to generate suffi-cient flows to trigger the Autohaler.
