Answer to Question 1

A
Feedback:
Salmeterol (Serevent) adult and pediatric (12-year-old and older): two puffs every 12 hours; or two puffs 30 to 60 minutes before exercise. Therefore, options B, C, and D are incorrect.

Answer to Question 2

B
Feedback:
If lidocaine is used for ventricular arrhythmias related to cardiac surgery or digoxin toxicity, serum levels should be monitored regularly to determine the appropriate dose and to avoid the potential for serious proarrhythmias and other adverse effects. Neurological assessment may indicate adverse effects but would not confirm lidocaine toxicity. Renal and hepatic function would not confirm lidocaine toxicity.
