Final answer:
The best location for a peripheral IV to administer chemotherapy is the cephalic vein in the upper arm.
Step-by-step explanation:
The best location for a peripheral IV to administer chemotherapy is the cephalic vein. This vein is located in the upper arm and is commonly used for the placement of IV catheters.
Chemotherapy drugs can be delivered directly into the bloodstream through a catheter in the cephalic vein, allowing the drugs to quickly circulate throughout the body.
Other potential locations for a peripheral IV include the basilic vein and the median cubital vein, but the cephalic vein is often preferred due to its accessibility and size.
