A nurse is assessing a patient who has peritonitis.Which of the following findings should the nurse expect?

Choice A rationaleA rigid abdomen is a classic finding in peritonitis, an inflammation of the peritoneum. The inflammation causes the abdominal muscles to become tense and board-like as a protective mechanism. This rigidity is often accompanied by severe abdominal pain that is exacerbated by movement or palpation.Choice B rationaleIncreased urinary output is not a typical finding in peritonitis. In fact, due to fluid shifts and potential dehydration from the inflammatory process and decreased oral intake, urinary output may be decreased. Normal adult urinary output is generally considered to be at least 0.5 mL/kg/hour.Choice C rationaleFrequent bowel movements are not characteristic of peritonitis. Peritonitis often leads to decreased bowel motility and potentially ileus due to the inflammation affecting the gastrointestinal tract. Bowel sounds may be diminished or absent rather than frequent.Choice D rationaleHyperactive bowel sounds are not typically associated with peritonitis. Initially, bowel sounds might be present, but as the inflammation progresses and ileus develops, bowel sounds usually become hypoactive or absent. Hyperactive bowel sounds are more commonly associated with early bowel obstruction or gastroenteritis.
