Question 1 of 5
A nurse is preparing to administer a scheduled dose of warfarin to a client. Which of the following laboratory tests should the nurse review prior to administration?
Correct Answer: D
Rationale: The correct answer is D: PT (Prothrombin Time). Before administering warfarin, the nurse should review the PT because warfarin is an anticoagulant that works by inhibiting clotting factors, particularly factor II (prothrombin). Monitoring PT helps assess the effectiveness of warfarin therapy and ensures the client's blood is not too thin, increasing the risk of bleeding. A: WBC (White Blood Cell count) is not relevant to monitoring warfarin therapy. B: PTT (Partial Thromboplastin Time) is not specific for monitoring warfarin therapy. C:
Total iron-binding capacity is not related to monitoring warfarin therapy.
