A nurse is caring for a client who has been taking warfarin and has an international normalized ratio (INR) time of 5. Which of the following medications should the nurse anticipate the provider to prescribe?
Correct answer
D
Rationale
An INR of 5 indicates excessive anticoagulation. Vitamin K reverses warfarin's effects, lowering INR. Ferrous sulfate, heparin, and prednisone are not appropriate for this purpose.
