What is a hematoma, and how can it be minimized during venipuncture?

• A. A bruise from bleeding under the skin; minimize by proper needle angle, steady technique, and applying pressure after the draw.
• B. A swelling due to infection; minimize by ignoring.
• C. A blood clot inside vein; minimize by bending the needle.
• D. A hairline fracture of the arm; minimize by massage.

Answer: (A)

A hematoma is a bruise that forms when blood leaks into the surrounding tissue after a vein is punctured during venipuncture. It’s not an infection or a clot inside the vein; it’s superficial bleeding into the tissue. To minimize it, use a controlled needle angle and a steady puncture, stabilize the vein so there’s minimal movement, and apply firm pressure at the puncture site after withdrawing the needle to stop the bleeding. These steps limit tissue trauma and prevent blood from seeping into the tissues. The other descriptions describe infection-related swelling, a clot within the vessel, or a fracture, which are not hematomas and require different management.
