NCLEX RN Practice Question

The symptoms described—swelling, coolness, and pallor around the insertion site—are classic indications of infiltration, which occurs when the infused solution leaks into surrounding tissues. The correct intervention is to pause the fluid therapy to prevent further leakage and remove the catheter from the site. Elevating the affected limb helps reduce swelling, and notifying the health care provider is essential for further evaluation or treatment. Restarting the therapy at an alternative location ensures the continuation of necessary care. Applying heat is contraindicated in infiltration because it can increase the risk of tissue damage. Tight bandages or increasing the rate of infusion would worsen complications and should be avoided.
