A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which clinical finding is most concerning?

  • A. Headache
  • B. Prothrombin time (PT) of 15 seconds
  • C. Elevated liver enzymes
  • D. Peripheral edema
Correct Answer: A

Rationale: The correct answer is A: Headache. In a client with atrial fibrillation taking warfarin (Coumadin), a headache can be indicative of bleeding, which is a serious complication requiring immediate assessment and intervention. Monitoring for signs of bleeding is crucial when on anticoagulant therapy. Choices B, C, and D are not the most concerning. A prothrombin time of 15 seconds is within the therapeutic range for a client on warfarin, elevated liver enzymes may indicate liver dysfunction but are not directly related to the medication's side effects, and peripheral edema is not typically associated with warfarin use or atrial fibrillation in this context.
