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.

Related Questions
Correct Answer is A
Explanation
A. Correct. Angiotensin-converting enzyme (ACE. inhibitors can contribute to prerenal acute renal failure, especially in clients with preexisting cardiovascular disease. These medications may cause vasodilation and decrease blood flow to the kidneys, leading to impaired kidney function.
B. Incorrect. Beta-blockers are not directly associated with prerenal acute renal failure.
C. Incorrect. Calcium channel blockers are not typically associated with prerenal acute renal failure.
D. Incorrect. Thiazide diuretics may cause electrolyte imbalances and metabolic disturbances, but they are not a common cause of prerenal acute renal failure.
QUESTIONS
Correct Answer is C
Explanation
A. Incorrect. Decreased blood volume and hypovolemia may contribute to prerenal acute renal failure, but they are not the primary pathophysiological processes that lead to edema in acute renal failure.
B. Incorrect. Increased vascular permeability and leakage of fluid into tissues are not the primary mechanisms of edema in acute renal failure.
C. Correct. In acute renal failure, the impaired filtration and reduced excretion of fluid by the kidneys lead to fluid retention and edema in various parts of the body.
D. Incorrect. Excessive fluid intake and fluid overload may contribute to fluid retention and edema in prerenal acute renal failure, but they are not the primary pathophysiological process in acute renal failure.
