Which sign in integumentary assessment indicates infection or inflammation?

• A. Warmth
• B. Cyanosis
• C. Edema
• D. Erythema

Answer: (A)

Warmth is a direct indication of increased tissue temperature from the inflammatory process. When infection or inflammation is present, blood vessels in the affected area dilate and more blood flows to the skin, and immune cells generate heat through metabolic activity. Palpating the skin to assess temperature helps detect this active inflammatory state, making warmth a clear and practical sign. Cyanosis points to oxygenation issues, not specifically infection or inflammation. Edema reflects fluid buildup and swelling, which can occur for many reasons and isn’t a direct measure of inflammatory heat. Erythema shows redness from vasodilation, which accompanies inflammation as well, but warmth specifically signals the temperature change associated with active inflammatory processes.
