Client education is an important aspect of medication administration, so a nurse is discussing the use of Coumadin and its potential effects with their client. What is the BEST advice the nurse can share with the client regarding their INR blood test?
1) Many medications and certain foods containing vitamin K can change the level of the INR results.
2) The INR results will change day by day.
3) Wait until you return for your next visit to review INR results.
4) Ask your primary care provider for advice based on the INR results.
