A patient who suffered a laceration while doing woodwork in his garage will have his wound treated under local anesthesia achieved using lidocaine and epinephrine
The nurse who will assist with the procedure should recognize that epinephrine performs what function in this situation? A) Promoting vasodilation
B) Prolonging the effects of lidocaine
C) Preventing adverse effects of lidocaine
D) Blocking the afferent nerve pathways
B
Feedback:
Lidocaine has a rapid effect, and, when combined with epinephrine, this effect is prolonged. Epinephrine can promote vasoconstriction, not vasodilation, and it neither prevents adverse effects nor blocks afferent nerve pathways.
