A) Phlebitis can develop.
B) Gangrene can set in.
C) Necrosis of the skin will develop.
D) Cold packs will need to be used to reduce the pain.
A
Feedback:
Because the venous access device traumatizes the vein wall and disturbs the flow of blood cells in the vein, there is a potential for phlebitis, inflammation of the vein, and thrombus formation (development of a clot). Gangrene is not an issue; necrosis of the skin depends on the fluid being infused and if it has infiltrated; and warm compresses are used, not cold packs.
