Aclient with a diagnosis of colon cancer has opted for a treatment plan that will include several rounds of chemotherapy. what vascular access device is most likely to meet this client's needs?

I think the vascular access device that is most likely to meet this client's need is An implanted central venous access device (CVAD). An implanted venous access port is a device used to give treatments and take blood. The port is a small container that is placed under your skin, usually in your upper chest. A port can alos be placed in the abdomen or arms. 

Hmmm i'm not sure about this one
