Final answer:
The nurse should stop the IV infusion, elevate the client's left arm, and apply heat to the distal hand.
Step-by-step explanation:
Based on the given information, the nurse should take the following actions:
- Stop the IV infusion
- Elevate the client's left arm
- Apply heat to the distal hand
The IV site is showing signs of infiltration, which is characterized by swelling, blanching, and coolness to the touch. Infiltration occurs when the IV fluid leaks into the surrounding tissues instead of flowing into the vein. Stopping the IV infusion will prevent further infiltration, elevating the arm will help reduce swelling, and applying heat can promote blood flow and help dissolve the infiltrated fluid.
