The healthcare provider places an order for a colonoscopy. The nurse would question this order if the client had which condition?

Colonoscopy is an endoscopic procedure that allows for direct visualization of the large intestine and distal ileum. While it is the gold standard for screening, it carries a risk of bowel perforation, especially when the intestinal wall is acutely inflamed. Clinical judgment is required to balance the need for diagnosis against the risk of peritonitis. A. Diverticulitis: During an acute episode, the diverticula are severely inflamed, thin-walled, and prone to rupture under the pressure of insufflation used during the procedure. Colonoscopy is typically contraindicated during the acute phase of diverticulitis to avoid causing an iatrogenic perforation. The exam is usually deferred for 6 to 8 weeks. B. Constipation: Chronic constipation is a common indication for a colonoscopy to rule out structural obstructions or colorectal malignancies. While a rigorous bowel prep is necessary to clear stool for visualization, the condition itself does not increase the procedural risk. It is a standard diagnostic use case. C. Irritable bowel syndrome: This functional disorder is often diagnosed after a colonoscopy has ruled out organic diseases like inflammatory bowel disease or cancer. The procedure helps confirm the absence of mucosal lesions or structural abnormalities. It is a safe and common practice for these patients. D. Stomach cancer: A colonoscopy may be performed in patients with gastric malignancies to screen for synchronous lesions or metastatic spread in the lower GI tract. The procedure does not pose an elevated risk because of the primary stomach pathology. It is a routine part of a comprehensive oncological workup.
