Which of the following is a characteristic feature of cellulitis?

Cellulitis is an acute bacterial infection of the skin and the underlying tissue, which is characterized by specific signs and symptoms. The correct answer highlights these hallmark features: local heat, redness, pain, and swelling. When cellulitis occurs, the affected area typically becomes red due to increased blood flow and inflammation, feels warm to the touch as the body responds to the infection, is painful, and shows swelling as fluid accumulates in the tissues.

This combination of symptoms helps distinguish cellulitis from other skin conditions. Unlike chronic dryness, which relates to skin barrier issues or conditions like eczema, cellulitis indicates a more acute and systemic response to infection. Bleeding under the skin may suggest other conditions, such as a bruise or a bleeding disorder, rather than suggesting an infection like cellulitis. The presence of a rash can indicate various dermatological conditions, including allergic reactions or viral infections, but it does not specifically align with the typical clinical presentation of cellulitis. Thus, the correct response clearly encapsulates the essential characteristics of this condition.
