Question 1 of 5

The nurse evaluates the effects of warfarin by monitoring what lab test?

Correct Answer: D

Rationale: The correct answer is D: Prothrombin time (PT) and international normalized ratio (INR). Warfarin is an anticoagulant medication that works by inhibiting vitamin K-dependent clotting factors. Monitoring PT and INR levels helps assess the effectiveness and safety of warfarin therapy. PT measures the time it takes for blood to clot, while INR standardizes PT results. Platelet count (
A) assesses clot formation ability, not warfarin effects. APT (
B) primarily evaluates the intrinsic pathway of coagulation. RBC count (
C) measures oxygen-carrying capacity, unrelated to warfarin effects.
