EMT Signs and Symptoms Practice Test

The key idea is that diverticulitis inflames diverticula in the sigmoid colon, which sits in the left lower quadrant of the abdomen. That inflammation produces a localized, prominent pain in the lower left area, making abdominal pain in the left lower quadrant the most characteristic symptom. Fever can occur if there’s infection, and vomiting or changes in bowel habits may happen, but they’re not as defining as the focal LLQ pain. So the best sign to identify diverticulitis is pain specifically in the left lower quadrant.
