A nurse is preparing a client for a renal cancer diagnostic procedure. The client asks about the purpose of a renal ultrasound. How should the nurse respond?
"A renal ultrasound helps visualize the structures of the kidney and may detect tumors or abnormalities."
"A renal ultrasound is used to confirm the presence of metastases in other organs."
"A renal ultrasound is performed to directly visualize and biopsy the tumor within the kidney."
"A renal ultrasound assesses blood flow within the kidney to evaluate its function."
The Correct Answer is A
A) Correct. A renal ultrasound is a non-invasive imaging test that helps visualize the structures of the kidney. It can detect tumors, cysts, and other abnormalities.
B) Incorrect. While a renal ultrasound is important for assessing the kidney, it is not typically used to confirm metastases in other organs. Imaging tests like CT scans or MRIs are more suitable for that purpose.
C) Incorrect. While a renal ultrasound can detect tumors within the kidney, it is not used for direct biopsy. Biopsy procedures are separate and may be performed if a tumor is detected.
D) Incorrect. While a renal ultrasound provides information about kidney structure, it is not primarily used to assess blood flow or kidney function. Other tests like Doppler ultrasound or renal scintigraphy may be used for that purpose.
