Which of the following is not a sign of peritonitis?

The presence of skin rashes is not traditionally associated with peritonitis. Peritonitis is an inflammation of the peritoneum, which can occur due to infection or irritation, often following abdominal surgery, trauma, or perforation of organs. The common signs of peritonitis include abdominal distension, rebound tenderness, and fever.

Abdominal distension occurs because of fluid accumulation or gas buildup in the peritoneal cavity, leading to noticeable expansion of the abdomen. Rebound tenderness is a clinical sign that suggests irritation of the peritoneum; it occurs when pressure is applied to the abdomen and then quickly released, causing pain. Fever is a common physiological response to inflammation or infection, making it another typical sign of peritonitis.

In contrast, skin rashes are indicative of dermatological issues or systemic diseases, but they do not correlate with the internal abdominal processes associated with peritonitis. This distinction is essential for recognizing and diagnosing the condition correctly.
