Final answer:
McBurney's point is located in the lower right quadrant of the abdomen. It is a common site for tenderness in cases of appendicitis.
Step-by-step explanation:
In an ER, a nurse would identify McBurney's point in the lower right quadrant of the abdomen.
McBurney's point is located about two-thirds of the distance from the umbilicus (belly button) to the right anterior superior iliac spine (bony prominence in the lower right abdomen). It is a common site for tenderness in cases of appendicitis, which is inflammation of the appendix.
By identifying McBurney's point and assessing for tenderness, the nurse can contribute to the diagnosis of appendicitis and facilitate appropriate treatment for the adolescent.
