What does tenderness at McBurney's point indicate in Esther's assessment?

Tenderness at McBurney's point is a significant clinical indicator for appendicitis. McBurney's point is located in the right lower quadrant of the abdomen, approximately one-third of the distance from the anterior superior iliac spine to the umbilicus. When a clinician assesses for appendicitis, they look for tenderness at this specific location because it correlates with irritation of the peritoneum that occurs when the appendix becomes inflamed.

In the case of appendicitis, as the appendix becomes inflamed, it can cause pain that often starts around the belly button and then shifts to the right lower quadrant, specifically at McBurney's point. This classic presentation helps healthcare providers differentiate appendicitis from other abdominal conditions that aren't characterized by the same localization of pain. Therefore, tenderness at McBurney's point is a strong indication of appendicitis and can guide further diagnostic and treatment decisions.
