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 Asthma is not a contraindication for sumatriptan. Sumatriptan is a selective serotonin receptor agonist used to treat migraines by constricting blood vessels in the brain. It does not have a significant impact on respiratory conditions like asthma. Choice B rationale Kidney disease is not a contraindication for sumatriptan. However, caution is advised when using sumatriptan in patients with severe renal impairment due to potential accumulation of the drug and its metabolites. Choice C rationale Rheumatoid arthritis is not a contraindication for sumatriptan. Sumatriptan’s mechanism of action does not interfere with the inflammatory processes involved in rheumatoid arthritis. Choice D rationale Coronary artery disease (CAD) is a contraindication for sumatriptan. Sumatriptan can cause vasoconstriction of coronary arteries, which can exacerbate CAD and increase the risk of myocardial infarction or other cardiac events.
