Practice Question
A nurse is caring for a client who has a new prescription for warfarin. The nurse should use the results of which of the following diagnostic tests to monitor the effect of this therapy?
Answer Choices:
Correct Answer:
Prothrombin time (PT))
Rationale:
✔️Warfarin is an oral anticoagulant that works by inhibiting vitamin K-dependent clotting factors.
✔️The therapeutic effect of warfarin is monitored by measuring the prothrombin time (PT), which assesses the blood’s ability to clot.
✔️The International Normalized Ratio (INR) is often calculated from PT to standardize the results across different laboratories.
✔️PT/INR helps ensure the client is within a therapeutic range, reducing the risk of clot formation while avoiding excessive bleeding.
✔️The other tests, such as aPTT, platelet count, and WBC count, are not appropriate for monitoring warfarin therapy.
