A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the LPN/LVN monitor closely while the client is taking this medication?

  • A. Blood glucose level
  • B. Prothrombin time (PT) and INR
  • C. Serum potassium level
  • D. Serum creatinine level
Correct Answer: B

Rationale: The LPN/LVN should closely monitor Prothrombin time (PT) and INR (Choice B) levels in a client receiving warfarin. These values are crucial to ensure the medication's effectiveness and prevent complications like bleeding. Monitoring blood glucose level (Choice A) is not directly relevant to warfarin therapy. While serum potassium level (Choice C) and serum creatinine level (Choice D) are important for other conditions or medications, they are not specifically required to be monitored when a client is on warfarin.
