Which of the following is NOT a sign or symptom of inflammation?

The choice of ecstasy as the option that is not a sign or symptom of inflammation is appropriate because ecstasy is not related to the physiological processes associated with inflammation. Inflammation is a biological response to harmful stimuli, and its primary signs and symptoms include fever, leukocytosis, and edema.

Fever is a systemic response that often occurs during inflammation as the body attempts to create an environment that is less favorable for pathogens. Leukocytosis refers to an increase in white blood cells, which is commonly observed as the immune system responds to infection or injury. Edema, which is characterized by swelling due to the accumulation of fluid, typically occurs in the inflamed tissues as a result of increased vascular permeability.

Ecstasy, however, is a term commonly associated with a recreational drug that induces feelings of euphoria and is unrelated to inflammation. Thus, it correctly identifies a choice that does not fit within the context of the inflammation process.
