Which vein runs along the outer side of the arm and is commonly used for IV access and blood draws?

Explanation:
The outer (lateral) side of the arm is served by the cephalic vein, which runs just beneath the skin along the arm and forearm. Its superficial path makes it easy to palpate and access, so it’s a common site for IV lines and blood draws when visible. The basilic vein sits on the inner (medial) side of the arm, which can be less convenient to access, and the median cubital vein is located in the elbow crease, connecting the cephalic and basilic veins. There isn’t a standard “median vein” used in clinical practice. So the vein that fits the description best is the cephalic vein.
