The health care provider is considering the use of sumatriptan (Imitrex) for a 54-year-old male patient with migraine headaches. Which information obtained by the nurse is most important to report to the health care provider?

A. Oriented to person, place, and year: Meningitis often causes alterations in mental status, including confusion and disorientation. Therefore, the client may not be fully oriented to person, place, and time.

B. Severe headache: Headache is a hallmark symptom of meningitis and is often described as severe and persistent. It may be accompanied by other symptoms such as photophobia (sensitivity to light) and phonophobia (sensitivity to sound).

C. Bradycardia: Bradycardia is not typically associated with meningitis. In fact, tachycardia (elevated heart rate) may be present due to fever and systemic inflammation.

D. Blurred vision: While meningitis can lead to increased intracranial pressure, which may manifest as papilledema (swelling of the optic disc), blurred vision is not a common presenting symptom of meningitis. Visual changes are more commonly associated with conditions affecting the optic nerve or retina.

A. Patient has slight elevations in liver function test results: Phenytoin is primarily metabolized by the liver, and elevated liver function tests may indicate impaired liver function, potentially affecting the metabolism and clearance of phenytoin. Consultation with the healthcare provider is warranted to assess the risk-benefit ratio of administering phenytoin in the presence of liver function abnormalities.

B. Patient's most recent blood pressure is 156/92 mm Hg: While hypertension is not a contraindication for phenytoin administration, it is important to monitor blood pressure, especially considering the potential cardiovascular side effects of the medication. However, elevated blood pressure alone does not typically warrant consultation before administering phenytoin.

C. Patient experiences an aura before seizures: Experiencing an aura before seizures is a common phenomenon in patients with epilepsy and does not necessarily contraindicate the use of phenytoin. In fact, phenytoin is commonly prescribed to prevent seizures, including those preceded by an aura.

D. Patient has tonic-clonic seizures: Phenytoin is indicated for the treatment and prevention of tonic-clonic seizures, among other seizure types. Therefore, the presence of tonic-clonic seizures would not typically warrant consultation before administering phenytoin.
