Why might a nurse administer heparin and warfarin concurrently to a client with deep vein thrombosis?

Warfarin takes several days to work, so the IV heparin will be used until the warfarin reaches a therapeutic level.
Heparin works better when given with warfarin.
Warfarin enhances the effect of heparin.
Heparin is used to control the side effects of warfarin.

The correct answer is: Warfarin takes several days to work, so the IV heparin will be used until the warfarin reaches a therapeutic level.

A nurse may administer heparin and warfarin concurrently to a client with deep vein thrombosis because warfarin takes several days to reach its full effectiveness, so the IV heparin is used in the meantime to prevent blood clots. This is known as bridging therapy and it is important to prevent any further complications. The other options are incorrect because they do not accurately explain why heparin and warfarin are given together. Warfarin does not enhance the effect of heparin, nor does heparin control the side effects of warfarin. Additionally, while heparin may work better when given with warfarin, this is not the main reason for the concurrent use of these medications in treating deep vein thrombosis.
