The provider gives K.N. a low dose of vitamin K orally, asks him to hold his warfarin dose that evening, and asks him to come back tomorrow for another prothrombin time (PT) and INR blood draw.
 
  Why is K.N. instructed to take the vitamin K?

Question 2

The health care provider does a brief focused history and physical examination, orders additional laboratory tests, and determines that there are no signs of bleeding other than the nosebleed, which has stopped.
 
  The provider discovers that K.N. recently started to take daily doses of an over-the-counter proton pump inhibitor (PPI), omeprazole (Prilosec OTC), for heartburn.
 
  What happened when K.N. began taking the PPI?
 
  What should K.N. have done to prevent this problem?

Answer to Question 1

The goal of vitamin K therapy is to reverse the excessive anticoagulation of his blood to bring his INR
down to the goal levels.

Answer to Question 2

A drug interaction occurred. The PPI prolonged the effects of the warfarin. As a result, K.N. had an
increased risk of bleeding

He should have called the anticoagulant clinic before starting the PPI to check whether there could
be a drug interaction.
