Which site should be avoided for routine peripheral IV insertion when possible?

Rationale: A. Areas of flexion, such as the wrist, elbow (antecubital fossa), or joints, should be avoided whenever possible for routine peripheral IV insertion. Placing an IV in these areas increases the risk of complications because movement can cause mechanical irritation of the vein, dislodgement of the catheter, infiltration, phlebitis, or occlusion of the IV line. Frequent bending or movement can also be uncomfortable for the client and make it difficult to secure the catheter properly. B. Upper extremity veins are the preferred locations for routine peripheral IV insertion. They are generally accessible, easy to monitor, and allow for patient mobility. Choosing a vein in the upper extremity supports effective infusion and reduces the risk of complications compared with lower extremity sites. C. A stable, palpable vein is ideal for IV insertion because it is easier to cannulate, less likely to collapse, and allows for a secure placement that reduces the risk of infiltration or dislodgement. This is considered a best practice rather than a site to avoid. D. The non-dominant forearm is a preferred site because it typically allows the client greater freedom of movement with the dominant hand and provides a convenient, accessible vein for IV therapy. It is not a site to avoid.
