Questions: Which is the correct interpretation of the finding of hypertension in a child who has been diagnosed as having nephroblastoma? The nephroblastoma is growing. The nephroblastoma is in stage V . The nephroblastoma secretes excessive renin. The nephroblastoma has a pseudocapsule around itself.

The answer is the third one: The nephroblastoma secretes excessive renin.

Explanation for each option:

1. The nephroblastoma is growing.

   • Incorrect. While tumor growth can cause various symptoms, hypertension specifically is not directly indicative of tumor growth alone.

2. The nephroblastoma is in stage V.

   • Incorrect. Staging of nephroblastoma (Wilms' tumor) is based on the extent of the disease and spread, not directly on the presence of hypertension.

3. The nephroblastoma secretes excessive renin.

   • Correct. Nephroblastoma (Wilms' tumor) can lead to hypertension due to the secretion of renin by the tumor. Renin is an enzyme that regulates blood pressure, and its excessive secretion can cause hypertension.

4. The nephroblastoma has a pseudocapsule around itself.

   • Incorrect. The presence of a pseudocapsule is a characteristic of the tumor but does not directly explain the occurrence of hypertension.

Summary: The correct interpretation of the finding of hypertension in a child diagnosed with nephroblastoma is that the tumor secretes excessive renin, which leads to elevated blood pressure.
