Which of the following symptoms is NOT one of the cardinal signs of inflammation?
A
Swelling (tumor)
B
Pain (dolor)
C
Redness (rubor)
D
Fever (pyrexia)
Verified step by step guidance1
Understand the concept of inflammation: Inflammation is the body's response to injury or infection, characterized by a set of cardinal signs that help identify the process.
Learn the cardinal signs of inflammation: The four primary signs are swelling (tumor), pain (dolor), redness (rubor), and heat (calor). These are localized symptoms at the site of inflammation.
Recognize that fever (pyrexia) is a systemic response: Unlike the cardinal signs of inflammation, fever is a whole-body response to infection or injury, not localized to the site of inflammation.
Compare the options provided: Swelling, pain, and redness are all cardinal signs of inflammation, while fever is not included in this list.
Conclude that fever (pyrexia) is NOT one of the cardinal signs of inflammation, as it is a systemic symptom rather than a localized one.
