Certified Wound Care Associate (CWCA) Practice Exam

Question: 1 / 400

Which of the following signs may indicate infection in a wound?

Flaky skin, increased mobility, decreased drainage

Increased redness, swelling, warmth, pain, and purulent drainage

The presence of increased redness, swelling, warmth, pain, and purulent drainage is indicative of infection in a wound. These signs are characteristic of the inflammatory response that occurs when the body is responding to an infectious agent. Redness and warmth arise from increased blood flow to the area as the immune system sends white blood cells to fight off infection. Swelling is due to the accumulation of fluid and immune cells at the site of the injury, while pain results from the release of inflammatory mediators that sensitize nerve endings. Purulent drainage, which can appear yellow or greenish, indicates the presence of pus, a common sign of infection containing dead white blood cells, bacteria, and tissue debris. Recognizing these signs is crucial for prompt management and treatment of potential infections, which can significantly affect healing outcomes.
