Answer to Question 1

A
Feedback:
When given sublingually, nitroglycerin is absorbed directly into the systemic circulation and acts within 1 to 3 minutes. If the medication has not produced an effect in 5 minutes, it should be repeated. The nitroglycerin tablets have an onset of action of 1 to 3 minutes, not 5 to 60 minutes.

Answer to Question 2

C
Feedback:
Therapeutic effects are usually apparent with the first 2 to 3 weeks of drug therapy for active TB.
