A nurse is inserting an IV catheter for a client who requires fluid replacement. Which of the following actions should the nurse take?

Choice A reason: Applying the tourniquet 15 cm (6 in) above the insertion site is incorrect. The tourniquet should be applied about 7.5 cm (3 in) above the site to engorge the vein without excessive pressure. Applying it too high reduces effectiveness and increases discomfort. Choice B reason: Checking for pulsation at sites proximal to the tourniquet is unnecessary and inappropriate. Pulsation indicates an artery, not a vein, and IV catheters should never be inserted into arteries. This step does not belong in IV insertion. Choice C reason: Anchoring the vein by stretching the skin 2.5 cm (1 in) proximal to the insertion site is correct because it stabilizes the vein, prevents rolling, and facilitates smooth catheter insertion. This technique reduces trauma and increases success rates. Choice D reason: Wiping the skin dry before inserting the catheter is incorrect. The skin should be cleansed with antiseptic and allowed to air dry completely to reduce infection risk. Wiping it dry compromises sterility.
