The nurse is assessing a client who is being considered for anticoagulant therapy. What aspect of the client's health history should the nurse follow up most closely?

A. The client's last menstrual period was 10 days ago: This factor is less concerning for anticoagulant therapy compared to a history of gastrointestinal ulcers. The primary concern for anticoagulants is the risk of bleeding. B. The client has a history of gastrointestinal (GI) ulcers: Anticoagulants increase the risk of bleeding, and individuals with a history of GI ulcers are more prone to gastrointestinal bleeding. Close monitoring and possible adjustments to the therapy are necessary. C. The client has a history of recurrent urinary tract infections: While recurrent urinary tract infections (UTIs) may indicate an underlying issue, they do not directly affect the decision to start anticoagulant therapy. D. The client's current body mass index is 32: A body mass index (BMI) of 32 indicates obesity, which can affect medication dosing and the metabolism of drugs. However, the more immediate concern with anticoagulant therapy is the risk of bleeding.
