A nurse is caring for a female client who has rheumatoid arthritis and asks the nurse if it is safe for her to take aspirin. The nurse should recognize which of the following findings in the client's history is a contraindication to this medication?

A. Migraine headaches are not a contraindication to aspirin use; in fact, aspirin is sometimes used for mild migraine relief. B. A history of gastric ulcers is a contraindication to aspirin therapy because aspirin is an NSAID that can irritate the gastric mucosa, increasing the risk of bleeding or ulcer recurrence. C. Glaucoma is not affected by aspirin use and is not a contraindication. D. Amenorrhea (absence of menstruation) is unrelated to the safety profile of aspirin.
