Pharmacology Proctored ATI Practice Exam

A client with an INR of 5.2 while on warfarin therapy indicates that the client is at an increased risk of bleeding due to their blood being too thin. In this scenario, the nurse should prepare to administer Vitamin K. Vitamin K is the antidote for warfarin overdose or when INR levels are excessively high. By administering Vitamin K, it will help reverse the effects of warfarin and reduce the risk of bleeding complications. The other options are incorrect: - Heparin is not the appropriate medication in this situation as it is not the antidote for warfarin overdose. - Aspirin is a different type of medication used for its antiplatelet effects and is not the antidote for high INR levels due to warfarin. - Acetaminophen is a pain reliever and does not have a role in reversing the effects of anticoagulant therapy like warfarin.
