Final answer:
The statement that a screening colonoscopy can positively identify sigmoid diverticulitis is false, as CT scans are the typical diagnostic tool for this condition.
Step-by-step explanation:
The statement 'Screening colonoscopy was performed with findings that were positive for sigmoid diverticulitis' can be considered false. Although a colonoscopy may reveal signs of diverticulitis, it is not the primary method used to diagnose the condition. Instead, diverticulitis is usually diagnosed with a CT scan. In cases of diverticulitis, treatment options vary depending on the severity of the condition. Mild cases may be treated with oral antibiotics and a liquid diet, whereas severe presentations may require intravenous antibiotics, hospitalization, and bowel rest. Complications such as abscess or perforation necessitate surgical intervention.
