Question

A patient on warfarin (Coumadin/Jantoven) has an INR of 6. Which medication would you anticipate administering?

1) Vitamin K
2) Aspirin
3) Heparin
4) Acetaminophen

Answer 1

For a patient with an INR of 6 on warfarin, you would administer Vitamin K to lower the INR and reduce the risk of bleeding.

Step-by-step explanation:

If a patient on warfarin (Coumadin/Jantoven) has an INR of 6, it is considered excessively high and indicates a risk for serious bleeding. The medication you would anticipate administering to counteract this would be Vitamin K, which is required for the synthesis of certain clotting factors and can help lower the INR, reducing the risk of hemorrhage. Aspirin and heparin are both anticoagulants that would further increase the risk of bleeding, and acetaminophen does not have any significant effect on INR. Therefore, among the options provided, Vitamin K is the correct choice for managing a patient with an elevated INR due to warfarin.
