Which sign is most specific for an infection at the ostomy site?

• A. Malaise
• B. Fever
• C. Erythema
• D. Drainage from incision- purulent

Answer: (D)

Purulent drainage is the sign that most specifically indicates an infection at the ostomy site. Purulent means pus-like material, reflecting the presence of bacteria and an inflammatory response with neutrophils. While fever or malaise can occur with infections, they are systemic and not specific to the ostomy site. Erythema can be caused by irritation or dermatitis from adhesives or output contact and isn’t definitive for infection. Normal healing drainage is typically serous or clear, not purulent. So when you see purulent drainage at the ostomy site, it most strongly points to an infection. If this occurs, close monitoring and prompt assessment are warranted.
