In monitoring the effectiveness of warfarin therapy for a client with a history of atrial fibrillation, which laboratory value should the nurse monitor?

  • A. Activated partial thromboplastin time (aPTT)
  • B. Prothrombin time (PT) and international normalized ratio (INR)
  • C. Platelet count
  • D. Erythrocyte sedimentation rate (ESR)
Correct Answer: B

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are crucial laboratory values to monitor the effectiveness of warfarin therapy in clients with atrial fibrillation. These values help ensure that the client is within the therapeutic range and that the anticoagulant effect of warfarin is appropriate.
