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

Rationale: A. Select a site on the client’s dominant arm: While either arm can be used, the nondominant arm is typically preferred to reduce interference with daily activities. Using the dominant arm may be more uncomfortable for the client post-insertion. B. Elevate the client’s arm prior to insertion: Elevating the arm can reduce venous filling, making veins less visible and harder to access. Instead, the arm should be in a dependent position to encourage venous distension. C. Apply a tourniquet below the venipuncture site: The tourniquet must be applied 10 to 15 cm (4 to 6 inches) above the intended insertion site to promote vein engorgement and visibility, not below it. D. Choose a vein that is palpable and straight: A vein that is straight and palpable is ideal for IV insertion because it offers a predictable path and is less likely to be damaged during catheter advancement, reducing complications.
