A nurse is teaching a client who has a new prescription for sumatriptan (Imitrex) tablets to treat migraine headaches. Which of the following instructions should the nurse include?

Choice A reason: Analgesics are medications that relieve pain by blocking pain signals or reducing inflammation. They include nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, and acetaminophen. However, analgesics are not very effective in treating trigeminal neuralgia, as they do not address the underlying cause of the pain, which is the compression or irritation of the trigeminal nerve.

Choice B reason: Antihistamines are medications that block the effects of histamine, a chemical that causes allergic reactions such as itching, sneezing, and swelling. They include diphenhydramine, cetirizine, and loratadine. Antihistamines are not effective in treating trigeminal neuralgia, as they do not affect the trigeminal nerve or its function.

Choice C reason: Antibiotics are medications that kill or inhibit the growth of bacteria that cause infections. They include penicillin, amoxicillin, and ciprofloxacin. Antibiotics are not effective in treating trigeminal neuralgia, as they do not target the trigeminal nerve or its pathology.

Choice D reason: Anticonvulsants are medications that prevent or reduce the frequency and severity of seizures by stabilizing the electrical activity of the brain. They include carbamazepine, gabapentin, and phenytoin. Anticonvulsants are the most effective medications in treating trigeminal neuralgia, as they reduce the abnormal firing of the trigeminal nerve that causes the pain. Anticonvulsants are considered the first-line therapy for trigeminal neuralgia and can provide significant relief for most clients.

Choice A: Limit fluid intake to prevent incontinence. This is incorrect because limiting fluid intake can lead to dehydration, urinary tract infections, and kidney stones. Fluid intake should be adequate to maintain hydration and flush out bacteria from the urinary tract.

Choice B: Provide regular perineal care to prevent skin breakdown. This is correct because reflex incontinence can cause urine leakage and skin irritation, which can increase the risk of infection and pressure ulcers. Regular perineal care can help keep the skin clean and dry, and prevent complications.

Choice C: Administer hypotonic IV fluids. This is incorrect because hypotonic IV fluids can cause fluid overload, hyponatremia, and cerebral edema. Hypotonic IV fluids are not indicated for clients with reflex incontinence.

Choice D: Teach Kegel exercises to strengthen the pelvic floor. This is incorrect because Kegel exercises are effective for clients with stress or urge incontinence, but not for clients with reflex incontinence. Reflex incontinence is caused by a loss of voluntary control over the bladder due to a spinal cord injury, and Kegel exercises cannot restore this function.
