A patient with a venous thromboembolism (VTE) is started on enoxaparin (Lovenox) and warfarin (Coumadin). The patient asks the nurse why two medications are necessary. Which response by the nurse is accurate?

"Enoxaparin will work right away, but warfarin takes several days to begin preventing clots."

"Enoxaparin will start to dissolve the clot, and warfarin will prevent any more clots from forming"

"Because of the risk for a blood clot in the lungs, it is important for you to take more than one blood thinner."

"Taking both blood thinners greatly reduces the risk for another clot to form."
