Which statement correctly identifies why epinephrine is used with local anesthetic agents?
1. Epinephrine use produces higher analgesia levels.
2. Epinephrine use prolongs surgical time.
3. Epinephrine use lowers the risk of bacterial infection.
4. Epinephrine use reduces the occurrence of hypertension.
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.
