An adolescent who is brought to the emergency department (ED) by his parents has the following symptoms: periumbilical pain that peaks at 4-hour intervals followed by right lower quadrant pain, which is followed by vomiting. Based on these data, which condition does the nurse suspect?
Correct Answer: C
Rationale: Periumbilical pain shifting to the right lower quadrant (McBurney’s point) with vomiting is characteristic of appendicitis . Meckel’s diverticulum may cause bleeding, omphalitis is umbilical infection, and ulcerative colitis involves chronic diarrhea, not acute localized pain.
