A nurse is caring for a client who is receiving a continuous IV infusion. The nurse notes that the skin around the catheter's insertion site is edematous and cool. Which of the following actions should the nurse take first?

Choice A reason: Documenting infiltration records the event but does not address the immediate issue. Edema and coolness suggest fluid leakage into tissues, which can cause damage if not stopped. Documentation is secondary to halting the infusion, as it only logs data without mitigating the ongoing extravasation harming the client’s tissue integrity.Choice B reason: Applying a warm compress may increase blood flow and reduce swelling later, but it does not stop the fluid leakage causing the edema. The priority is to cease the infusion to prevent further tissue damage from ongoing infiltration, making this a subsequent action rather than the first step.Choice C reason: Elevating the arm can help reduce swelling by aiding venous return, but it does not address the source of the problem—fluid leaking from the IV. Stopping the infusion first prevents additional extravasation, as elevation alone cannot halt the ongoing tissue damage caused by the continuous fluid administration.Choice D reason: Stopping the infusion is the priority because edema and coolness indicate infiltration, where IV fluid leaks into surrounding tissues. Ceasing the flow prevents further damage, such as tissue necrosis or nerve injury, which can occur if fluid continues to accumulate, making this the critical first step in management.
