A nurse is caring for a client with acute renal failure who is undergoing a renal nuclear scan. What information should the nurse provide to the client about this diagnostic test?
"You will need to fast for 24 hours before the nuclear scan."
"The nuclear scan will assess your kidney function by measuring the glomerular filtration rate (GFR)."
"The procedure involves inserting a catheter into the bladder to obtain a urine sample."
"You will receive a small amount of radioactive material intravenously for the scan."
The Correct Answer is D
A. Incorrect. Fasting is not typically required before a renal nuclear scan.
B. Incorrect. The renal nuclear scan does not directly measure the glomerular filtration rate (GFR), which is typically assessed through blood tests.
C. Incorrect. A renal nuclear scan does not involve inserting a catheter into the bladder to obtain a urine sample.
D. Correct. A renal nuclear scan, also known as a renal scintigraphy, involves injecting a small amount of radioactive material intravenously. The radioactive material is taken up by the kidneys, and the scan creates images that assess kidney function and blood flow.

D. Incorrect. Deep breathing exercises are not specific interventions for correcting metabolic acidosis.
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.
