Nurse Gretchen is discussing the use of cocaine as a local anesthetic with a nursing student. Which statement by the student indicates understanding of this agent?
- A.
“Anesthetic effects develop slowly and persist for several hours.”
- B.
“Cocaine is a local anesthetic administered by injection.”
- C.
“Vasoconstrictors should not be used as adjunct agents with this drug.”
- D.
“When abused. cocaine causes physical dependence.”
Correct Answer
C. “Vasoconstrictors should not be used as adjunct agents with this drug.”Explanation
Cocaine should not be combined with epinephrine or other vasoconstrictors. because it causes vasoconstriction itself. and the combination could precipitate severe hypertension. Cocaine has a rapid onset of effects. which last about 1 hour. It is used only topically for anesthesia. Although subject to widespread abuse with profound psychological dependence. it does not cause substantial physical dependence.Rate this question:

The client asks the nurse to explain the action of infiltration anesthesia. The nurse’s response is based on the knowledge that infiltration anesthesia:

Is applied only to mucous membranes to provide local anesthesia.
- B.
Blocks a specific group of nerves in tissues close to the operative area.
- C.
Blocks sensation to an entire limb. or a large area of the face.
- D.
Produces numbing to large. regional areas such as the lower abdomen and legs.
Correct Answer
B. Blocks a specific group of nerves in tissues close to the operative area.Explanation
Infiltration anesthesia blocks a specific group of nerves close to the operative area by diffusion of a drug into the tissues. It is used to anesthetize small areas. Topical anesthetics are applied to mucous membranes. Nerve blocks provide anesthesia to a large surface area. Spinal anesthesia affects large. regional areas.Rate this question:

All narcotics. regardless of their origin. reduce pain by:
- A.
Stimulating opiate receptors
- B.
Promoting the release of excitatory transmitters
- C.
Releasing large quantities of endorphin
- D.
Blocking the mu receptors
Correct Answer
A. Stimulating opiate receptorsExplanation
It is the stimulation of cerebral opiate receptors that reduces pain. Excitatory transmitters are not released during administration of morphine. Endorphin release is not associated with narcotic pain relief. The mu receptors mediate analgesia and are not blocked during narcotic administration.Rate this question:

In addition to analgesia. narcotic effects include:
- A.
Euphoria. diarrhea. increased respirations
- B.
Euphoria. miosis. nausea and vomiting
- C.
