A client is prescribed an IV infusion of 0.9% Sodium Chloride at 125 mL/hr. The nurse notes swelling, coolness, and pain at the insertion site. Which action should the nurse take first?
✓ Correct Answer: Option C
The signs (swelling, coolness, pain) indicate IV infiltration, where fluid leaks into surrounding tissue. The priority is to stop the infusion and remove the catheter to prevent further tissue damage.
