Explanation
A. Atropine is not used as an antidote for warfarin overdose. It is primarily used to treat bradycardia and certain types of heart block.
B. Vitamin K is the antidote for warfarin overdose. Warfarin inhibits vitamin K-dependent clotting factors, and vitamin K helps reverse its effects by promoting clotting factor synthesis in the liver.
C. Protamine is used as an antidote for heparin, not warfarin. It binds to heparin to neutralize its anticoagulant effects.
D. Epinephrine is not used as an antidote for warfarin overdose. It is primarily used in emergencies such as severe allergic reactions (anaphylaxis) or cardiac arrest.
