Question 1 of 5

A nurse is caring for a patient who has a new prescription for warfarin. Which of the following diagnostic test results should the nurse use to monitor the therapy's effect?

Correct Answer: C

Rationale: The correct answer is C: Prothrombin time (PT). PT measures the extrinsic pathway of the coagulation cascade, which warfarin affects by inhibiting the synthesis of vitamin K-dependent clotting factors. Monitoring PT helps ensure the patient is within the therapeutic range to prevent clotting or bleeding. Platelet count (
A) assesses platelet function, not the effectiveness of warfarin. White blood cell count (
B) is unrelated to warfarin therapy. Activated partial thromboplastin time (aPTT) (
D) primarily assesses the intrinsic pathway of coagulation and is not specific to monitoring warfarin therapy.
