The client who is having a scalp laceration sutured will be receiving local anesthesia with lidocaine (Xylocaine) that contains epinephrine. The nurse knows that the purpose of this drug combination is to:

1. Decrease bleeding at the site of trauma.

2. Increase vasodilation at the site of the laceration.

3. Decrease blood pressure in individuals who are hypertensive.

4. Ensure that infection at the wound site will not occur.
