A nurse is preparing to initiate IV access for an older adult client. Which of the following sites should the nurse select when initiating the IV for this client?

A. Radial vein of the inner arm. This is correct because this site is easily accessible, has good blood flow, and has less risk of complications such as infection, thrombosis, or infiltration. B. Great saphenous vein of the leg. This is incorrect because this site is not recommended for older adults due to poor circulation, increased risk of thrombophlebitis, and difficulty in monitoring. C. Dorsal plexus vein of the foot. This is incorrect because this site is prone to edema, infection, and injury, and can interfere with mobility and comfort. D. Basilic vein of the hand. This is incorrect because this site is more painful, has smaller veins, and can cause nerve damage or occlusion if not inserted carefully.
