What could occur if a needle is inserted through the vein?

• A. Hemorrhage
• B. Infiltration of fluids into surrounding tissue
• C. Severe pain at the site
• D. Loss of consciousness

Answer: (B)

When a needle is inserted through the vein, infiltration of fluids into the surrounding tissue can occur. This situation typically arises when the needle goes beyond the vein and punctures the surrounding tissue, allowing the fluid intended for the vascular system to leak outside of the vein. Infiltration can lead to swelling, localized pain, and discoloration in the area where the fluid accumulates. It is an important consideration during venipuncture as proper technique is crucial to keeping the needle within the vein and avoiding this complication. Maintaining proper angle and insertion depth is key to preventing infiltration. Though other options may relate to potential complications of venipuncture, infiltration specifically addresses the consequence of the needle penetrating through the vein and causing fluid to escape into the surrounding tissue.
