McBurney's point is located in which quadrant of the abdomen?

• A. Left lower quadrant
• B. Right lower quadrant
• C. Right upper quadrant
• D. Left upper quadrant

Answer: (B)

McBurney's point is a surface landmark for the base of the appendix, which sits in the right lower quadrant. It’s located roughly one-third of the way from the anterior superior iliac spine to the umbilicus. In appendicitis, pain often starts around the umbilicus and then localizes to this point as the parietal peritoneum becomes irritated. So the correct quadrant is the right lower quadrant. The other quadrants contain different organs (left lower with parts of the colon and sigmoid, right upper with liver and gallbladder, left upper with stomach and spleen), which is why the site for appendiceal pain—and thus McBurney's point—fits RLQ.
