When selecting a site for a peripheral IV insertion, which site should be chosen?

• A. Select a vein in the client's dominant arm
• B. Choose the most proximal vein in that extremity
• C. Choose a vein that is soft on palpation
• D. Select a site distal to previous venipuncture attempts

Answer: (C)

Evaluating vein quality by palpation is the key idea when choosing a peripheral IV site. A vein that feels soft and pliable on palpation is the best choice because it indicates a patent, easily collapsible vessel that can dilate to accommodate a cannula without leaking into surrounding tissue. This reduces the risk of infiltration and phlebitis and makes cannulation easier and more reliable. Veins that feel hard, ropey, or rigid are less desirable because they may be sclerosed or inflamed, making cannulation difficult and increasing complication risk. While other considerations—like preserving proximal veins for future access or avoiding the dominant arm when possible—are important in broader planning, they are secondary to selecting a vein that feels soft and suitable for cannulation in the moment.
