A patient with a history of duodenal ulcer is admitted to the emergency department with reports of pain. The nurse should assess for this pain by palpating in which abdominal quadrant?

A. The right upper quadrant is typically associated with gallbladder or liver issues, not duodenal ulcers. B. The right lower quadrant is primarily associated with appendicitis or other conditions involving the appendix. C. The left upper quadrant is where the duodenum is located, making it the appropriate area to assess for pain related to a duodenal ulcer. D. The left lower quadrant is often associated with conditions affecting the sigmoid colon or left ovary but not typically with duodenal ulcers.
