The nurse is assisting while the physician is suturing a wound in the urgent care clinic. The physician asks for lidocaine with epinephrine. The nurse identifies the primary reason for adding epinephrine to the lidocaine is what effect?
A) It will sting more when it is injected into the tissue.
B) Risk of systemic absorption is increased.
C) Local effect is increased.
D) Bleeding at the wound site is increased.
C
Feedback:
There is less risk of systemic absorption and increased local effects if these drugs are combined with epinephrine. Epinephrine causes vasoconstriction, which reduces bleeding, slows absorption, and makes the duration of effect longer. It does sting more when injected, but that is not a reason to use it.
