Prior to cannulation, reddened and warm skin over the fistula most likely indicates?

• A. Aneurysm
• B. Thrombosis
• C. Normal healing
• D. Infection

Answer: (D)

Reddish, warm skin over the fistula before cannulation signals inflammation from an infection in the access area. Infections cause increased blood flow and warmth, sometimes with redness and tenderness, and they pose a risk of spreading or sepsis if cannulated. Because of this risk, you would avoid cannulating at that site and assess for other signs of infection, document the finding, and follow facility protocol—this may include notifying the clinician, obtaining cultures if ordered, and starting or adjusting antibiotics as indicated. By contrast, an aneurysm would present as a visible bulge or pulsatile area and is not defined by warmth or redness. Thrombosis often leads to a loss of bruit and thrill and may cause poor fistula function rather than local inflammatory signs. Normal healing would not include warmth and redness. So the presence of reddened, warm skin points to infection rather than the other possibilities.
