Which medication is commonly prescribed for a client diagnosed with peritonitis?

A client diagnosed with peritonitis often requires antibiotics to address the infection in the abdominal cavity. Ciprofloxacin is a broad-spectrum antibiotic that is effective against various types of bacteria, making it suitable for treating infections associated with peritonitis. The use of antibiotics is essential in managing this condition, as peritonitis can result from bacterial infections often following perforation of the gastrointestinal tract.

Lactulose, while useful in treating hepatic encephalopathy by reducing blood ammonia levels, is not indicated for peritonitis. Loperamide is an antidiarrheal medication that can worsen the symptoms of acute abdominal conditions, including peritonitis, as it would reduce intestinal motility and potentially exacerbate the infection. Pantoprazole, a proton pump inhibitor, is used for conditions related to excess stomach acid but does not treat infections. Thus, ciprofloxacin stands out as the appropriate choice for a client with peritonitis, as it directly addresses the underlying infection.
