A client with renal cancer is prescribed immunotherapy. The client asks the nurse about the purpose of this treatment. How should the nurse respond?

A) Correct. Monitoring vital signs, including blood pressure and heart rate, is a priority after a radical nephrectomy. Changes in blood pressure or heart rate can indicate potential complications.

B) Incorrect. Administering chemotherapy medications is not typically part of the immediate postoperative care for a radical nephrectomy.

C) Incorrect. Encouraging vigorous physical activity is not recommended immediately after a radical nephrectomy. The client will need time to recover and gradually resume normal activities.

D) Incorrect. Providing a high-sodium diet is not typically indicated after a radical nephrectomy. The client's diet will be based on their specific needs and any potential dietary restrictions.

A) Incorrect. The primary goal of a renal biopsy is to obtain a tissue sample for microscopic examination, not to remove the entire tumor.

B) Correct. A renal biopsy is performed to obtain a tissue sample from the kidney, which is then examined under a microscope to confirm the presence of cancer and provide further information about the type and grade of the tumor.

C) Incorrect. Assessing blood flow within the kidney is not the primary purpose of a renal biopsy. Other tests may be used for that purpose.

D) Incorrect. Evaluating kidney function is not the primary goal of a renal biopsy. There are other tests and assessments specifically designed for evaluating kidney function.
