What is a common assessment to perform for signs of peritonitis?

The most effective assessment for signs of peritonitis involves assessing for rebound tenderness. When peritonitis is present, the inflammation of the peritoneum can cause increased sensitivity and pain upon palpation of the abdomen. During this assessment, the healthcare provider gently presses on the abdomen and then quickly releases the pressure. If rebound tenderness is present, it's characterized by a surge of pain when the pressure is released, indicating irritation of the peritoneum. This is a classic sign that can indicate serious abdominal conditions, such as perforation or a severe infection, warranting immediate medical intervention.

In contrast, the other options do not directly indicate the presence of peritonitis. For instance, palpating for a pulse deficit is more relevant in assessing cardiovascular conditions. Checking for bowel sounds can provide information about the gastrointestinal function but is not specific to peritonitis, as bowel sounds may still be present in a variety of conditions. Measuring blood glucose levels is typically used to assess metabolic states and diabetic conditions, not abdominal inflammation. Therefore, rebound tenderness is essential in diagnosing peritonitis effectively.
