Question 1 of 5

A nurse is reporting a client's laboratory tests to the provider to obtain a prescription for the client's daily warfarin. Which of the following laboratory tests should the nurse plan to report to obtain the prescription for the warfarin?

Correct Answer: A

Rationale: The correct answer is A: INR. The International Normalized Ratio (INR) is used to monitor and adjust warfarin therapy. It measures the effectiveness of warfarin in thinning the blood and helps determine the appropriate dosage. A higher INR indicates the blood is too thin, while a lower INR indicates the blood is too thick. Fibrinogen level (
B) is not directly related to warfarin therapy. aPTT (
C) is used to monitor heparin therapy, not warfarin. Platelet count (
D) is important for assessing clotting function but is not specifically needed to adjust warfarin dosage.
