Question 1 of 5
The patient has been started on warfarin (Coumadin) for deep vein thrombosis. The patient asks when the medication will break up the clots. The nurse's best response would be:
Correct Answer: A
Rationale: The correct answer is A because warfarin (Coumadin) is an anticoagulant that works to prevent blood clot formation and growth, rather than directly breaking down existing clots. Warfarin inhibits the production of certain clotting factors in the liver, making it less likely for the clot to enlarge or new clots to form. This process does not result in immediate clot dissolution, so the patient needs to be aware that the medication's primary goal is prevention rather than immediate clot breakdown.
Choices B, C, and D are incorrect as they provide inaccurate information regarding the mechanism and timeline of action of warfarin in clot dissolution, leading to potential misinformation and confusion for the patient.
