Which site is described as the point midway between the umbilicus and the anterior iliac crest in the right lower quadrant?

• A. Rovsing's sign
• B. Murphy's sign
• C. Psoas sign
• D. McBurney's point

Answer: (D)

The main idea is using a surface landmark to localize the area of the appendix. McBurney's point lies in the right lower quadrant and roughly corresponds to the base of the appendix. It’s typically described as about one-third of the distance from the anterior superior iliac spine to the umbilicus, and tenderness there is a classic sign of acute appendicitis because inflammation irritates the parietal peritoneum over that spot. The other signs test different things: Rovsing's sign is pain in the RLQ when the LLQ is palpated (peritoneal irritation), Murphy's sign points to gallbladder disease, and the Psoas sign indicates irritation of the psoas muscle, often from a retrocecal appendix. So, the described RLQ landmark best matches McBurney's point.
