  • A. Bleeding
  • B. Arrhythmias
  • C. Blurred vision

Correct Answer: A

Rationale: A severe adverse effect of warfarin is bleeding. Warfarin is an anticoagulant medication that works by inhibiting blood clotting factors, which can lead to an increased risk of bleeding. Excessive bleeding can occur internally or externally, and it is crucial for individuals taking warfarin to be aware of this potential complication and seek medical attention if they experience any signs of bleeding.
