A nurse is planning to administer medications to a client who has trigeminal neuralgia. Which of the following medications should the nurse plan to administer to manage the client's pain?

A. Lorazepam: This medication is an anxiolytic and sedative, not indicated for neuropathic pain or trigeminal neuralgia. B. Fluoxetine: This is an SSRI antidepressant, primarily used for mood disorders, not for the treatment of neuropathic pain. C. Carbamazepine: This is the first-line treatment for trigeminal neuralgia. It is an anticonvulsant that stabilizes nerve membranes and reduces the hyperexcitability responsible for pain. D. Methylphenidate: A CNS stimulant, used for ADHD and narcolepsy, not for trigeminal neuralgia.
