Question 1 of 5

A nurse is preparing to administer a daily dose of warfarin to a client. Which of the following laboratory values should the nurse check prior to administration?

Correct Answer: B

Rationale: The correct answer is B: INR. The International Normalized Ratio (INR) is a crucial laboratory value to monitor before administering warfarin, an anticoagulant. INR helps assess the effectiveness and safety of warfarin therapy by measuring the clotting time of blood. This ensures that the dose is within the therapeutic range to prevent clotting or bleeding complications. Checking white blood cells (WB
C), platelets, or activated partial thromboplastin time (APTT) is not directly related to warfarin administration. WBC count indicates infection or inflammation, platelets assess clotting ability, and APTT evaluates the intrinsic pathway of coagulation. However, these values do not specifically guide warfarin dosing like the INR does.
