Question 1 of 5
A nurse is caring for a client who is on warfarin therapy for atrial fibrillation. The client's INR is 5.2. Which of the following medications should the nurse prepare to administer?
Correct Answer: C
Rationale: The correct answer is C: Vitamin K. A high INR level indicates the blood is too thin, increasing the risk of bleeding. Vitamin K is the antidote for warfarin toxicity as it helps reverse its effects and normalizes the INR. Atropine (
A) is used for bradycardia, epinephrine (
B) for anaphylaxis or cardiac arrest, and protamine (
D) for heparin overdose reversal. In summary, the nurse should administer Vitamin K to reverse warfarin's effects and lower the INR level.
