Practice Question
The nurse is preparing to administer warfarin to a client with deep vein thrombophlebitis. Which laboratory value would most clearly indicate that the client's warfarin is at therapeutic levels?
Answer Choices:
Correct Answer:
International normalized ratio (INR) between 2 and 3
Rationale:
🟢 The INR (International Normalized Ratio) is the most accurate and widely used measure to monitor the effectiveness of warfarin therapy, especially in clients being treated for conditions like deep vein thrombosis (DVT).
🟢 A therapeutic INR range of 2.0 to 3.0 indicates adequate anticoagulation for most conditions, including DVT and pulmonary embolism.
🟢 PT values alone are less reliable due to lab variability; the INR standardizes this measurement globally.
🟢 PTT is used for heparin monitoring, not warfarin, and hematocrit relates to anemia, not anticoagulation status.
