Question 1 of 5

A nurse is reviewing the laboratory results of a client who has been taking warfarin for 3 months. Which of the following laboratory results Indicates that the medication has been effective?

Correct Answer: C

Rationale: The correct answer is C: INR 2.0. INR (International Normalized Ratio) measures the effectiveness of warfarin in preventing blood clotting. A therapeutic range for INR in clients on warfarin is typically between 2.0 and 3.0. An INR of 2.0 indicates that the medication is within the desired range and is effectively anticoagulating the blood to prevent clot formation.


Choice A (Hgb 14 g/dL) is a normal hemoglobin level and does not directly reflect warfarin effectiveness.
Choice B (WBC count 10,000/mm3) measures white blood cells and is not related to warfarin efficacy.
Choice D (Platelets 150,000/mm3) is a normal platelet count and does not indicate the effectiveness of warfarin.
