Vitamin K is used in anticoagulation management for which purpose?

Explanation:
Vitamin K is used to reverse the anticoagulant effect of warfarin. Warfarin inhibits the enzyme that activates vitamin K–dependent clotting factors, reducing factors II, VII, IX, and X and lowering the blood’s ability to clot. Supplying vitamin K lets the liver re-synthesize these factors, restoring normal coagulation and lowering the risk of bleeding or correcting a dangerously high INR. This is specific to reversing warfarin; it isn’t used to treat hyperkalemia, infections, or to manage other types of anticoagulants.
