A nurse is preparing to insert an IV catheter for a client. Which of the following actions should the nurse plan to take?

A. Apply a tourniquet below the venipuncture site: The tourniquet should be applied above the venipuncture site to engorge the vein and make it more visible and easier to access. B. Choose a vein that is palpable and straight: A vein that is palpable, straight, and firm provides the best chance of successful IV insertion and reduces the risk of complications like infiltration or phlebitis. C. Elevate the client's arm prior to insertion: Elevating the arm can actually reduce venous filling and make vein access more difficult. Instead, the arm should be in a dependent position to promote vein distention. D. Select a site on the client's dominant arm: The non-dominant arm is generally preferred for IV insertion to minimize interference with daily activities and reduce discomfort.
