Which of the following is a sign that suggests burn wound infection?

• A. Increased purulence
• B. Normal wound appearance
• C. Rapid wound healing
• D. Decreased heart rate

Answer: (A)

Purulence in a burn wound indicates infection. When bacteria invade a wound, the body sends neutrophils and other immune cells to the site, producing pus. This results in thick, opaque drainage that is often yellow or green, signaling bacterial growth and an escalating inflammatory response. In burn injuries, the skin barrier is already compromised, so a shift to purulent drainage is a classic local sign that infection may be developing and healing is being hindered. By contrast, a normal wound appearance suggests no infection, rapid wound healing indicates progress without infectious interference, and a decreased heart rate is not typical of infection ( infections more commonly cause an increased heart rate due to systemic inflammation).
