The nurse is assessing a 14-year-old girl with a tumor. Which of the following findings would indicate Ewing sarcoma?
Correct Answer: B
Rationale: Ewing sarcoma is a rare bone cancer primarily affecting children and adolescents, typically arising in flat bones like the pelvis, chest wall (e.g., ribs), or vertebrae, and the diaphysis of long bones. A hallmark is a palpable, non-tender mass, making non-tender swelling on the ribs a strong indicator, as it aligns with the tumor's common chest wall location and lack of initial pain sensitivity. Dull bone pain above the knee suggests a long bone issue, possibly osteosarcoma, which favors the metaphysis, not Ewing's typical diaphysis site. An abdominal mass crossing the midline is more characteristic of Wilms tumor or neuroblastoma, not Ewing sarcoma. An asymptomatic upper back mass could suggest various tumors, but lacks specificity for Ewing's flat bone preference. Nurses must recognize this presentation to facilitate prompt imaging and biopsy, critical for early diagnosis and treatment planning in pediatric oncology.
