Question 1 of 5
The nurse discovers a patient receiving warfarin is bleeding. What drug would the nurse prepare to counteract this drug?
Correct Answer: D
Rationale: The correct answer is D: Vitamin K. Vitamin K is the antidote for warfarin, an anticoagulant that inhibits vitamin K-dependent clotting factors. Administering Vitamin K helps replenish the depleted clotting factors, stopping the bleeding. Other choices are incorrect because: A (Vitamin E) does not directly counteract warfarin's mechanism of action, B (Protamine Sulfate) is used to reverse heparin's effects, not warfarin, and C (Calcium Gluconate) is used for calcium channel blocker toxicity, not warfarin-induced bleeding.
