She describes the pain as constant and crampy, initially located around the umbilicus but now localized to the right lower quadrant. She also reports a fever and nausea. Her last menstrual period was a week ago. Her vitals are normal except for a temperature of 101.5°F (38.6°C). On physical examination, she exhibits tenderness in the right lower quadrant of the abdomen.
