Answer to Question 1

D
Torsades de pointes is a dysrhythmia that can occur with prolongation of the QT interval and can progress to fatal ventricular fibrillation. A prolonged QT interval does not signal the development of AV block, bradycardia, or SVT.

Answer to Question 2

B
Two tetracyclines are used for periodontal disease. Doxycycline inhibits collagenase, which de-stroys connective tissue in the gums. It is not used for anti-inflammatory effects. Minocycline is used to reduce bleeding and pocket depth and to inhibit bacterial growth.
