- B. Apply sequential compression devices to lower extremities.
- C. Monitor the client's pedal pulses every shift.

The client diagnosed with acute deep vein thrombosis is receiving a continuous heparin drip, an intravenous anticoagulant. The healthcare provider orders warfarin (Coumadin), an oral anticoagulant. Which action should the nurse take?

- B. Check the client's INR prior to beginning Coumadin.
- C. Clarify the order with the health-care provider as soon as possible.
- D. Administer the Coumadin along with the heparin drip as ordered.
Correct Answer: D
Rationale: Heparin and warfarin are often overlapped for 3–5 days in acute DVT until warfarin’s INR is therapeutic (D). Discontinuing heparin (A) is premature, INR (B) is checked later, and clarification (C) is unnecessary.
