Question 1 of 5
A nurse is providing discharge teaching about warfarin to a client who has deep-vein thrombosis. The nurse should instruct the client to obtain which of the following laboratory tests monthly?
Correct Answer: D
Rationale: The correct answer is D: INR. The International Normalized Ratio (INR) is used to monitor the effectiveness of warfarin therapy. It measures the clotting tendency of the blood and helps ensure the client is within the therapeutic range to prevent clotting or bleeding. Monthly monitoring is crucial to adjust the warfarin dosage as needed. Platelet count (
A) assesses the number of platelets in the blood, not related to warfarin therapy. aPTT (
B) and Fibrinogen (
C) are not specific to monitoring warfarin therapy.
