Which item in a client's history would cause the nurse to question the prescription of sumatriptan?

Sumatriptan is a medication commonly used to treat acute migraine attacks, and it belongs to a class of drugs known as triptans. When considering a client’s health history and potential contraindications for the use of sumatriptan, uncontrolled hypertension is a significant factor. Triptans can lead to vasoconstriction, which can raise blood pressure. This risk becomes particularly concerning for individuals with uncontrolled hypertension, as it may exacerbate cardiovascular issues and increase the likelihood of serious complications such as stroke or heart attack.

Given this context, if a client has a history of uncontrolled hypertension, the prescription of sumatriptan would warrant careful evaluation and potentially raise concerns about their safety. It is essential for healthcare providers to review a patient's medical history thoroughly before prescribing medications, especially those that can have significant cardiovascular effects. In this case, the presence of uncontrolled hypertension makes it necessary to question the appropriateness of sumatriptan.
