A client with acute renal failure is scheduled for a renal biopsy. What information should the nurse provide to the client about this procedure?
"You will need to fast for 12 hours before the biopsy."
"The biopsy will assess your kidney function by measuring the glomerular filtration rate (GFR)."
"The procedure involves inserting a needle through the back to obtain a tissue sample from the kidneys."
"A renal biopsy will examine the blood vessels in your kidneys and assess blood flow to the kidneys."
The Correct Answer is C
A. Incorrect. Fasting is not typically required before a renal biopsy.
B. Incorrect. The renal biopsy does not directly measure the glomerular filtration rate (GFR), which is usually assessed through blood tests.
C. Correct. A renal biopsy is a procedure in which a needle is inserted through the skin and into the kidneys to obtain a small tissue sample for examination. This allows for a direct assessment of kidney tissue and helps identify the cause of kidney dysfunction.
D. Incorrect. While a renal biopsy can provide information about the kidney's structure, its primary purpose is to obtain a tissue sample for histological examination, not to assess blood flow.
