A nurse is caring for a client who has deep vein thrombosis and has been on heparin continuous infusion for 5 days. The provider prescribes warfarin PO without discontinuing the heparin. The client asks the nurse why both anticoagulants are necessary. Which of the following statements should the nurse make?

"I will call the provider to get a prescription for discontinuing the IV heparin today."

"Both heparin and warfarin work together to dissolve the clots."

"The IV heparin increases the effects of the warfarin and decreases the length of your hospital stay."

"Warfarin takes several days to work, so the IV heparin will be used until the warfarin reaches a therapeutic level."

Answer and Explanation

The Correct Answer is D

Rationale:

A. Discontinuing heparin abruptly without achieving therapeutic levels of warfarin increases the risk of thrombus formation.

B. Heparin and warfarin have different mechanisms of action, but they both serve to prevent clot formation.

C. Heparin and warfarin do not directly affect each other's therapeutic effects.

D. Warfarin takes time to reach therapeutic levels and become effective, so heparin is continued until warfarin is fully active.
