During intravenous procedures, how should proximal pressure be handled?

• A. Pressure is released prior to injecting, and maintained when drawing blood.
• B. Pressure is released only after completing the procedure.
• C. Pressure should be kept applied throughout the entire process.
• D. No pressure is ever required.

Answer: (A)

Proximal pressure helps stabilize and distend a vein to make venous access easier and safer. Release that pressure just before you begin the injection so the vein isn’t compressed when the needle enters, which helps the injected fluid enter the vein smoothly rather than being diverted into surrounding tissue. Once you’ve started drawing blood, keep the proximal pressure applied to maintain vein patency and reduce the chance of backflow or vein collapse during collection. This approach minimizes tissue damage during injection and supports a clean, uninterrupted blood draw.
