When selecting an IV site, which guideline helps minimize complications by avoiding previous puncture sites?

• A. Choose a proximal vein in the limb
• B. Choose a vein distal to previous venipuncture attempts
• C. Choose a vein that is hard and immobile
• D. Choose a vein in the non-dominant arm

Answer: (B)

Minimizing complications when starting an IV hinges on choosing a vein that hasn’t already been traumatized by needle sticks. Veins that have been punctured before can become damaged, scarred, or inflamed, which raises the risk of infiltration, phlebitis, hematoma, and failed cannulation. By selecting a vein distal to previous venipuncture attempts, you’re moving away from those damaged areas and toward healthier tissue, making cannulation easier and reducing complication risk. The other options don’t specifically avoid prior puncture sites, and they may involve veins that are harder to cannulate or don’t address vein health as directly.
