Question 5 of 5
Following long-term administration of warfarin sodium to a client with deep vein thrombosis, the nurse should expect which outcome?
Correct Answer: A
Rationale: After long-term warfarin for deep vein thrombosis, the nurse should expect the prothrombin time (PT) to be 1.5 to 2 times the normal value (or INR 2-3), indicating therapeutic anticoagulation. Warfarin inhibits vitamin K-dependent clotting factors, prolonging PT to prevent clot extension. PTT is more relevant for heparin, not warfarin, and hematocrit/hemoglobin levels aren't directly affected by anticoagulation unless bleeding occurs. PT prolongation is the standard measure of warfarin's efficacy in this context.
