A patient brought to the emergency department requires sutures. The prescriber orders a local anesthetic with epinephrine. The nurse understands that epinephrine is ordered to:
a. prevent hypertension induced by the anesthetic.
b. allow a reduced dose of the anesthetic.
c. reduce anesthetic-induced nausea.
d. reduce the pain of an injection.
B
Epinephrine prolongs absorption of the anesthetic, because it is an alpha1 agonist. It is frequently combined with a local anesthetic for this purpose, so that the amount of anesthetic required may be reduced. Local anesthetics do not induce hypertension; therefore, epinephrine would not be needed to prevent it. Epinephrine does not act as an antiemetic and would not reduce anesthet-ic-induced nausea. Epinephrine is not used to reduce the pain of an injection.
