A nurse is planning care for a client who has diverticulitis. The nurse should plan to monitor the client for which of the following complications of diverticulitis?

Choice A reason: An antipyretic medication is not the best answer because it does not address the client's low urine output. An antipyretic medication is a drug that lowers the body temperature by reducing the production of heat or increasing the loss of heat. It may help the client feel more comfortable, but it does not improve the kidney function or prevent dehydration.

Choice B reason: A diuretic medication is not the best answer because it may worsen the client's low urine output. A diuretic medication is a drug that increases the excretion of water and electrolytes by the kidneys. It may lower the blood pressure and reduce the fluid overload, but it may also cause dehydration, electrolyte imbalance, and kidney damage.

Choice C reason: A blood culture is not the best answer because it does not address the client's low urine output. A blood culture is a laboratory test that detects the presence of bacteria or other microorganisms in the blood. It may help identify the cause of the fever and guide the antibiotic therapy, but it does not improve the kidney function or prevent dehydration.

Choice D reason: A fluid bolus is the best answer because it may improve the client's low urine output. A fluid bolus is a rapid infusion of a large volume of fluid, usually isotonic saline or lactated Ringer's solution. It may increase the blood volume and pressure, improve the tissue perfusion, and stimulate the urine production. It may also help lower the fever by diluting the pyrogens and increasing the heat loss.

Choice A reason: Ulcerative colitis is not a complication of diverticulitis. Ulcerative colitis is a chronic inflammatory bowel disease that causes ulcers and inflammation in the colon and rectum. Diverticulitis is an acute condition that occurs when small pouches called diverticula in the colon become infected or inflamed.

Choice B reason: Dysphagia is not a complication of diverticulitis. Dysphagia is a term for difficulty swallowing, which can have many causes, such as stroke, nerve damage, or esophageal cancer. Diverticulitis affects the lower part of the digestive tract, not the upper part.

Choice C reason: Peritonitis is a complication of diverticulitis. Peritonitis is an inflammation of the peritoneum, the membrane that lines the abdominal cavity. It can be caused by a perforation or rupture of a diverticulum, which allows bacteria and fecal matter to enter the peritoneal space. Peritonitis is a serious and life-threatening condition that requires immediate medical attention.

Choice D reason: Crohn's disease is not a complication of diverticulitis. Crohn's disease is a chronic inflammatory bowel disease that can affect any part of the digestive tract, causing ulcers, fistulas, and strictures. Diverticulitis is an acute condition that affects only the colon, not the entire digestive tract.
