A client admitted with acute diverticulitis has experienced a sudden increase in temperature and reports a sudden onset of extreme abdominal tenderness. The nurse's rapid assessment reveals that the client's abdomen is uncharacteristically rigid on palpation. What is the nurse's best response?

Choice A reason: Guarding and rebound tenderness are signs of peritonitis, which is a serious complication of colonoscopy. Peritonitis is an inflammation of the peritoneum, the membrane that lines the abdominal cavity. It can be caused by perforation or puncture of the colon during the colonoscopy, which allows bacteria and fecal matter to enter the peritoneal space. The nurse should monitor the client for signs of peritonitis, such as abdominal pain, rigidity, fever, and leukocytosis.

Choice B reason: Nausea and vomiting are not specific signs of a complication of colonoscopy. They may be caused by other factors, such as the sedation, the bowel preparation, or the ingestion of food or fluids after the procedure. Nausea and vomiting may also be symptoms of other conditions, such as gastroenteritis, food poisoning, or pregnancy.

Choice C reason: Diarrhea is not a sign of a complication of colonoscopy. Diarrhea may be a normal consequence of the bowel preparation, which involves taking laxatives or enemas to clear the colon before the procedure. Diarrhea may also be caused by other factors, such as the ingestion of food or fluids after the procedure, or the presence of an underlying bowel disorder, such as irritable bowel syndrome or inflammatory bowel disease.

Choice D reason: Hyperactive bowel sounds are not a sign of a complication of colonoscopy. Hyperactive bowel sounds may indicate increased peristalsis, which is the movement of the digestive tract. Hyperactive bowel sounds may be a normal response to the bowel preparation, the ingestion of food or fluids after the procedure, or the stimulation of the colon during the colonoscopy. Hyperactive bowel sounds may also be present in conditions such as diarrhea, gastroenteritis, or intestinal obstruction.

Choice A reason: Gastritis is not the most likely condition that these clinical manifestations indicate. Gastritis is an inflammation of the stomach lining, which can cause abdominal pain, nausea, vomiting, and loss of appetite. Gastritis may cause heartburn or dyspepsia, but it does not usually cause dysphagia, which is difficulty swallowing.

Choice B reason: GERD is the most likely condition that these clinical manifestations indicate. GERD stands for gastroesophageal reflux disease, which is a chronic condition where the stomach acid flows back into the esophagus, causing irritation and inflammation. GERD can cause heartburn, which is a burning sensation in the chest or throat, dysphagia, which is difficulty swallowing or a feeling of a lump in the throat, and dyspepsia, which is indigestion or discomfort in the upper abdomen.

Choice C reason: Peptic ulcer disease is not the most likely condition that these clinical manifestations indicate. Peptic ulcer disease is a condition where there are open sores or ulcers in the lining of the stomach or duodenum, which can cause bleeding, perforation, or obstruction. Peptic ulcer disease can cause dyspepsia, which is indigestion or discomfort in the upper abdomen, but it does not usually cause heartburn or dysphagia, which are more characteristic of GERD.

Choice D reason: Pancreatitis is not the most likely condition that these clinical manifestations indicate. Pancreatitis is an inflammation of the pancreas, which can cause severe abdominal pain, nausea, vomiting, fever, and jaundice. Pancreatitis does not cause heartburn, dysphagia, or dyspepsia, which are more characteristic of GERD.
