Question: 1 / 400

Which of the following is NOT one of the cardinal signs of inflammation?

Heat

Pain

Swelling

Fever

In the context of inflammation, the cardinal signs traditionally recognized are heat, pain, swelling (also known as edema), and redness. When these signs occur, they indicate that the body is responding to injury or infection and are crucial for the healing process.

Fever, while it is a common systemic response to infection, is not considered a cardinal sign of inflammation affecting a specific area of the body. It typically indicates a more widespread response, often involving the entire body rather than localized tissue responses. Thus, fever is related to the immune response but does not fit within the classical definition of the cardinal signs directly associated with inflammation. Understanding the distinction helps clarify the specific localized responses that characterize inflammation compared to the systemic responses like fever, which is a broader manifestation of an ongoing immune process.
