Final answer:
Tranexamic acid is the correct choice to prevent surgical bleeding in a patient with liver disease, as it helps maintain blood clots and prevent excessive bleeding during surgery.
Step-by-step explanation:
The drug that could be used to prevent surgical bleeding in a patient with liver disease is tranexamic acid. Tranexamic acid works by inhibiting the breakdown of blood clots, thus helping to prevent bleeding during surgeries. While drugs like aspirin, heparin, and warfarin are anticoagulants that reduce clot formation, they are not suitable for preventing surgical bleeding in patients with liver disease due to an increased risk of bleeding.
