Answer to Question 1

ANS: D
Monitoring for reactive bronchospasm should consist of peak flow measurements or FEV1 be-fore and after therapy; auscultation for adventitious breath sounds; observation of the patient's breathing pattern and overall appearance; and, most essentially, communication with the patient during therapy to determine the perceived work of breathing.

Answer to Question 2

ANS: A
Breath-actuated nebulizers generate aerosol only during inspiration. It is true that breath-actuated pressure metered dose inhalers do not require good hand-breath coordination, and because of that they decrease aerosol medication waste. Patients with severe airway obstruction may not have the capability of generating enough flow to trigger the breath actuator.
