Answer to Question 1

Correct Answer: 3

Rationale 1: Local anesthetics act by blocking sodium channels. The blocking of sodium channels by local anesthetics is nonselective; therefore, both sensory and motor impulses are affected. Sensation and muscle activity in the treated area will be decreased temporarily. Because of their mechanism of action, local anesthetics are sometimes called sodium channel blockers.
