Final answer:
A child with testicular torsion would present acute symptoms such as severe scrotal pain and swelling. However, the provided information pertains to testicular cancer, which includes a lump or swelling in the testes and possibly pain, and is diagnosed by physical exam, ultrasound, and blood tests.
Step-by-step explanation:
A child presenting to the school nurse with testicular torsion is likely to show acute symptoms, which can include severe scrotal pain, swelling, nausea, and vomiting. This condition is a medical emergency and requires immediate attention to avoid serious complications. However, the information provided speaks about testicular cancer, not torsion. Signs and symptoms of testicular cancer might include a lump or swelling in one of the testes, possibly accompanied by pain. Heavy feeling in the scrotum, fluid accumulation, and discomfort in the lower abdomen or scrotum may also be noticed. Testicular cancer is confirmed through a physical exam, ultrasound, and blood tests and treated effectively with surgery, potentially followed by radiation and/or chemotherapy.
