Question 1 of 5
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?
Correct Answer: A
Rationale: The correct answer is A. Warfarin takes several days to work because it inhibits clotting factors that are already present in the bloodstream. Thus, the IV heparin will be continued until the warfarin reaches a therapeutic level to ensure continuous anticoagulation and prevent clot formation.
Explanation for why other choices are incorrect:
B: Discontinuing the IV heparin abruptly can increase the risk of clot formation as warfarin takes time to reach therapeutic levels.
C: IV heparin and warfarin do not directly affect the length of hospital stay, and IV heparin does not increase the effects of warfarin.
D: While both heparin and warfarin are anticoagulants, they do not work together to dissolve clots; rather, they prevent further clot formation.
