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 (International Normalized Ratio). The INR is a crucial test for monitoring warfarin therapy as it measures the effectiveness of the medication in preventing blood clots. A therapeutic INR range for clients on warfarin is typically between 2.0 and 3.0. Reporting the INR level to the provider will help determine if the client's warfarin dosage needs adjustment.
Fibrinogen level (B), aPTT (C), and Platelet count (D) are not directly related to monitoring warfarin therapy. Fibrinogen level reflects clotting ability, aPTT measures intrinsic clotting time, and platelet count assesses the number of platelets in the blood. While these tests are important for assessing overall coagulation status, they are not specific to monitoring warfarin therapy.
