The client diagnosed with acute vein thrombosis is receiving a continuous heparin drip, an intravenous anticoagulant. The health care provider orders warfarin (Coumadin), an oral anticoagulant. Which action should the nurse take?
Correct Answer: D
Rationale: The correct action for the nurse to take is to administer the Coumadin along with the heparin drip as ordered. Heparin and warfarin are often given together initially because warfarin takes a few days to become effective. Discontinuing the heparin drip prior to initiating Coumadin could leave the patient without anticoagulation coverage during the period when warfarin's effects are not yet established. Checking the client's INR prior to beginning Coumadin is important but not the immediate action to take when both medications are ordered together. Clarifying the order with the health care provider is unnecessary in this scenario as it is common practice to give heparin and warfarin concurrently in the transition period.
