When treating an infiltration of a non-vesicant IV solution, what is the first action the nurse should take?

When addressing an infiltration of a non-vesicant IV solution, the first action the nurse should take is to stop the infusion. This is crucial because allowing the infusion to continue can lead to further fluid accumulation in the surrounding tissues, which may worsen the patient's condition or prolong the infiltration. By stopping the infusion promptly, the nurse minimizes potential complications and allows for appropriate interventions to be implemented.

Following the cessation of the infusion, the nurse can then take additional actions, such as elevating the extremity to reduce swelling, applying warm compresses to encourage absorption of the infiltrated fluid, and ultimately notifying the healthcare provider if further medical intervention is needed. However, halting the infusion is the immediate priority in order to prevent further damage and facilitate the patient's comfort and healing.
