The nurse is preparing to administer warfarin (Coumadin), an oral anticoagulant, to a client with a mechanical valve replacement. The client's INR is 2.7. Which action should the nurse implement?
Correct answer
A
Rationale
INR 2.7 (A) is within the therapeutic range (2ÔÇô3) for mechanical valves, so administer warfarin. Vitamin K (B) reverses anticoagulation, holding (C) is unnecessary, and bleeding (D) is routine but not primary.
