What medication is typically administered for hematuria and bruising in a patient taking warfarin?

Vitamin K is the appropriate medication for a patient experiencing hematuria and bruising as a result of anticoagulation therapy with warfarin. Warfarin works by inhibiting vitamin K-dependent clotting factors, and if a patient develops bleeding symptoms, such as hematuria or bruising, it may indicate an over-anticoagulated state. Administering vitamin K serves to reverse the effects of warfarin by promoting the synthesis of clotting factors that require vitamin K, thereby aiding in the cessation of bleeding.

This use of vitamin K is particularly critical in managing patients who are anticoagulated with warfarin and show signs of bleeding, as it directly addresses the underlying cause related to the anticoagulation therapy. Emergency treatment requires monitoring and potentially adjusting the warfarin dosage, but vitamin K is the immediate intervention for counteracting excessive bleeding from the anticoagulation effect.
