Which measurement would provide the most specific information about the outcome of a paracentesis for a patient who has ascites?

Choice A reason: Hyperactive bowel sounds are not typically associated with peritonitis. Instead, peritonitis often leads to decreased or absent bowel sounds due to the inflammation and subsequent ileus (paralysis of the bowel), which slows down or halts peristalsis.
Choice B reason: Increased urinary output is not a common symptom of peritonitis. In fact, peritonitis can sometimes result in reduced urine output due to the body's response to infection and inflammation, which can affect kidney function.
Choice C reason: Frequent bowel movements are not characteristic of peritonitis. The inflammation in the peritoneal cavity often leads to bowel paralysis, resulting in decreased bowel movements rather than increased frequency.
Choice D reason: A rigid abdomen is a hallmark sign of peritonitis. The rigidity is due to the body's protective response to the severe inflammation in the peritoneal cavity, causing the abdominal muscles to tighten and become hard. This clinical sign, along with severe pain, can help healthcare providers diagnose peritonitis.

Choice A reason: The use of a colostomy bag is expected following surgery for colorectal cancer that involves the creation of a stoma. This does not indicate a complication.
Choice B reason: A loss of appetite is common after major surgery and can be managed with nutritional support and gradual reintroduction of food.
Choice C reason: Absent bowel sounds in the lower abdominal quadrants could indicate a paralytic ileus or bowel obstruction, which are serious complications requiring immediate intervention to prevent further issues such as bowel ischemia.
Choice D reason: Mild pain at the surgical site is expected and can be managed with prescribed pain medications. It does not indicate a serious complication.
