What feature is located at the point of a needle?

• A. Hub
• B. Bevel
• C. Barrel
• D. Plunger

Answer: (B)

The bevel of a needle is the feature located at its point. The bevel is the angled cut at the tip of the needle that sharpens the point, allowing it to penetrate the skin or tissue more easily. This design facilitates smoother insertion and minimizes discomfort for patients. Additionally, the bevel creates a hollow opening that allows medication or fluids to flow through when the needle is in use. In contrast, the hub is the part of the needle that connects it to the syringe. The barrel refers to the outer cylindrical part of a syringe that holds the medication, and the plunger is the component that fits inside the barrel and is used to draw up or expel fluid. Each of these parts plays a crucial role in the functionality of the syringe and needle system, but it is the bevel at the needle's tip that is specifically designed for effective penetration.
