A client is receiving heparin sodium 5000 units IV and oral warfarin sodium 2.5 mg PO for thrombophlebitis in the left leg. The nurse educated the client that heparin and warfarin are both used because:
the heparin provides anticoagulation until the warfarin becomes effective.
this combination facilitates the dissolving of the clot.
smaller doses of both drugs can be used with this method of administration.
this combination provides immediate maximum protection against clot formation.
The Correct Answer is A
A. Heparin acts quickly to provide immediate anticoagulation, while warfarin takes several days to reach therapeutic levels. Heparin ensures that the client is adequately anticoagulated during the initial phase while waiting for warfarin to take effect.
B. Neither heparin nor warfarin directly dissolves clots. They are both anticoagulants that prevent further clot formation and allow the body's natural processes (fibrinolysis) to break down the existing clot over time. The combination does not specifically facilitate the dissolution of clots.
C. This statement is misleading. The use of both medications is not primarily about reducing the doses. Instead, each medication has its own dosing based on the patient’s needs, and the combination is used for timing and efficacy rather than dose reduction.
D. While heparin does provide immediate anticoagulation, saying it provides "maximum protection" could be misleading. It does ensure effective anticoagulation in the short term, but the maximum effect is related to individual response and therapeutic levels, which vary. Additionally, once warfarin reaches therapeutic levels, it becomes the primary agent for long-term anticoagulation.
