A nurse is reviewing the health history of a client who experiences migraine headaches and has asked about a prescription for sumatriptan. Which of the following conditions should the nurse identify as a contraindication for taking sumatriptan?

Choice A rationale Sumatriptan is a selective serotonin receptor agonist that can cause vasoconstriction of cerebral blood vessels. While some clients with asthma might be more sensitive to medications, asthma itself is not a direct contraindication for sumatriptan use, as its mechanism of action does not primarily affect bronchial smooth muscle or respiratory function. Choice B rationale Kidney disease is not a contraindication for taking sumatriptan. The medication is primarily metabolized by the liver via monoamine oxidase and excreted renally. However, severe kidney impairment might affect drug clearance, but it is not a direct contraindication unless specified by a healthcare provider for a specific case. Choice C rationale Rheumatoid arthritis is an autoimmune disorder that affects the joints. Sumatriptan's mechanism of action is focused on the cranial vasculature and is unrelated to the inflammatory pathways of rheumatoid arthritis. Therefore, having rheumatoid arthritis does not pose a contraindication for the use of sumatriptan to treat migraines. Choice D rationale Sumatriptan causes selective vasoconstriction of intracranial blood vessels. However, it can also cause coronary artery vasoconstriction, leading to an increased risk of angina, myocardial infarction, or coronary vasospasm, especially in individuals with pre-existing coronary artery disease. Therefore, this condition is a major contraindication.
