The nurse is performing a routine assessment of an IV site for a client receiving both IV fluids and medications through the line. The client reports tenderness when the nurse touches the arm above the site. Which finding should the nurse expect which will require immediate intervention?

A. A sluggish blood return: While a sluggish blood return may indicate potential issues with the IV line, it does not require immediate intervention unless accompanied by other signs of complications. B. Cool sensation above the site: Cool sensation above the site may indicate impaired circulation, but it is not as concerning as other findings requiring immediate intervention. C. Iced streak tracking the vein: Correct! An iced streak tracking the vein suggests infiltration of IV fluids into the surrounding tissue, which can cause tissue damage and compromise the effectiveness of the IV therapy. Immediate intervention is needed to prevent further complications. D. Circumferential skin irritation: Circumferential skin irritation may indicate an allergic reaction or contact dermatitis, which requires attention but is not as urgent as an infiltration.
