A client with acute renal failure is experiencing metabolic acidosis. Which intervention should the nurse anticipate to help correct the acid-base imbalance?
Administering bicarbonate intravenously to raise pH levels.
Encouraging the client to consume more acidic foods.
Increasing fluid intake to dilute acid concentrations.
Promoting shallow breathing to retain carbon dioxide.
The Correct Answer is A
A. Correct. In acute renal failure, when the kidneys are unable to excrete acids properly, metabolic acidosis can occur. Administering bicarbonate intravenously helps raise the pH levels and correct the acid-base imbalance.
B. Incorrect. Encouraging the client to consume more acidic foods would worsen metabolic acidosis and is not a suitable intervention.
C. Incorrect. Increasing fluid intake is not a specific intervention for correcting metabolic acidosis. The focus should be on addressing the underlying acid-base imbalance.
D. Incorrect. Promoting shallow breathing to retain carbon dioxide is not a recommended intervention for correcting metabolic acidosis. Respiratory acidosis and metabolic acidosis are different types of acid-base imbalances with distinct causes and treatments.

Correct Answer is C
Explanation
A. Incorrect. Hypertension is a risk factor for prerenal acute renal failure, not postrenal.
B. Incorrect. While a UTI can cause kidney injury, it is not directly related to postrenal acute renal failure.
C. Correct. An enlarged prostate, also known as benign prostatic hyperplasia (BPH), can cause obstruction of the urinary tract and lead to postrenal acute renal failure. The obstruction prevents urine flow, causing pressure buildup in the kidneys and impairing kidney function.
D. Incorrect. Chronic kidney disease (CKD. is a risk factor for intrinsic acute renal failure, not postrenal.
Correct Answer is C
Explanation
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.
