A patient is brought to the emergency department for a superficial stab wound to the forearm. Sutures are required, and a prescriber orders a local anesthetic with epinephrine
The nurse understands that the rationale for the use of epinephrine with a local anesthetic is to cause which of the following effects?
a. Reduce anesthetic-induced nausea.
b. Prolong anesthetic absorption.
c. Reduce the pain of an injection.
d. Prevent hypertension induced by the anesthetic.
ANS: B
Epinephrine prolongs anesthetic absorption, because it is an alpha1 agonist. It is frequently combined with a local anesthetic to delay anesthetic absorption.
Epinephrine does not act as an antiemetic, therefore it would not reduce anesthetic-induced nausea.
Epinephrine is not used to reduce the pain of an injection.
Anesthesia does not induce hypertension, therefore epinephrine is not indicated for use in such cases.
