Answer to Question 1

ANS: C
To operate the device, patients twist the body of the device to load an internal spring, place the mouthpiece of the Respimat between the lips, and press a button to release the drug through a uniblock to create the aerosol, which is released over 1.1 to 1.4 sec, depending on the formulation configuration. The Respimat requires hand-breath coordination on the part of the patient, as does a pMDI, but because of the longer aerosolization time, it seems more likely that the patient will get a greater percent of emitted dose despite coordination issues.

Answer to Question 2

ANS: A
A patient with acute airway obstruction (wheezing, cough, dyspnea, and PEFR <60 of pre-dicted value) would receive up to three SVN treatments with a standard dose of albuterol, re-peated at 20-min intervals, or four puffs of pressurized MDI albuterol with a holding chamber (up to 12 puffs).
