What is a possible cause of pain upon removal of the needle?

• A. Needle barb
• B. Needle bevel
• C. Needle hub
• D. Syringe plunger

Answer: (A)

Pain on needle withdrawal is often caused by the barb on the needle snagging tissue as you pull out. That small raised edge at the tip can catch and tear tissue slightly, producing a brief sharp sensation when the needle is removed. The bevel mainly influences how the needle penetrates tissue, so it’s more involved in insertion than withdrawal pain. The hub and syringe plunger don’t normally cause pain during needle removal unless there’s a hardware issue, which is less typical. Using a clean, undamaged needle and withdrawing slowly along the same path helps minimize barb-related discomfort.
