The nurse is teaching a client who is receiving carbamazepine (Tegretol) for chronic trigeminal neuralgia. Which statement indicates that the client correctly understands the teaching?
a. "This drug will prevent seizures, which can occur because of trigeminal disease."
b. "I expect to have surgery soon, so I can stop taking this drug now."
c. "This medication is very successful in re-lieving pain. I am glad to be taking it."
d. "I will avoid drinking alcohol because it can add to the side effects of this medi-cine."
D
Carbamazepine is thought to interfere with the transmission of pain through slow fibers. It may decrease the paroxysmal afferent impulse that causes trigeminal pain. Trigeminal disease does not cause seizures. Drowsiness, dizziness, confusion, and risk for falls are adverse effects of this medication. Alcohol consumption increases these risks; therefore the client should not drink al-cohol when taking this medication. Seizure disorders may occur in clients who stop taking this medication. The dose should be decreased gradually. Pain relief varies with the person; some people find that this medication provides at least some relief.
