Answer to Question 1

Correct Answer: 2
Rationale: Epinephrine causes vasoconstriction, prolonging the time the anesthetic is present, and therefore prolongs procedure time. Epinephrine would cause hypertension, not prevent it. Epinephrine is not antibacterial and is not an analgesic.

Answer to Question 2

Correct Answer: 3
Rationale: All except lidocaine are classified as esthers. Lidocaine is classified as an amide, and amides produce fewer side effects than do esthers.
