What is the purpose of the bevel on a needle used for venipuncture?

To create a larger puncture in the vein

To facilitate smooth entry into the vein

The purpose of the bevel on a needle used for venipuncture is to facilitate smooth entry into the vein. The bevel is the angled part at the tip of the needle that creates a sharp point, allowing for easier penetration of the skin and the underlying tissue. This design minimizes trauma to the tissue as the needle is inserted, which helps in reducing pain and complications during the procedure. A smooth entry is crucial for ensuring that the needle slides into the vein without causing unnecessary damage to the vascular tissue, promoting a successful blood draw while also enhancing patient comfort.
