Question 1 of 5
You're educating a patient about Warfarin (Coumadin) and how it is used to treat blood clots. Which statements by the patient require you to re-educate them about how this medication works? Select all that apply:
Correct Answer: A,D
Rationale: Warfarin (Coumadin) does NOT dissolve blood clots. It prevents blood clots from forming, and if one is present, it will help prevent it from becoming bigger. If the blood clot becomes bigger it may break off and travel in blood circulation. This can lead to a pulmonary embolism, heart attack, or stroke. Warfarin (Coumadin) does NOT start working immediately. It takes about 3-5 days of scheduled doses to start achieving a therapeutic INR level. It is very common that a patient will be on Heparin while taking Warfarin until INR levels are therapeutic.
