A nurse is collecting data from a client who has diverticular disease. The nurse should expect the client to report abdominal pain in which of the following locations?

A. Upper left quadrant: Pain in the upper left quadrant is typically associated with disorders of the spleen, stomach, or pancreas. These structures are not directly involved in diverticular disease. Therefore, this location is not expected for diverticulitis symptoms. B. Lower right quadrant: Lower right quadrant pain is more characteristic of appendicitis or issues involving the terminal ileum. Although bowel disorders can cause generalized pain, diverticulitis classically affects the sigmoid colon, not the right side. C. Upper right quadrant: Upper right quadrant pain usually indicates biliary or hepatic issues, such as gallbladder disease or hepatitis. Because diverticula most commonly form in the sigmoid colon, this quadrant does not match expected findings. D. Lower left quadrant: Pain from diverticulitis is characteristically located in the left lower quadrant, where the sigmoid colon is situated. Inflammation of diverticula in this region causes localized tenderness, cramping, and changes in bowel habits.
