A client is admitted to the hospital with acute renal failure, and the nurse is reviewing the client's medication list. Which medication is a common cause of intrinsic acute renal failure?

A. Correct. Nonsteroidal anti-inflammatory drugs (NSAIDs), including ibuprofen, are known to cause kidney damage and are a common cause of intrinsic acute renal failure, especially when used in high doses or for extended periods.

B. Incorrect. Loop diuretics, such as furosemide, are not typically associated with intrinsic acute renal failure.

C. Incorrect. Metformin is not a common cause of intrinsic acute renal failure. However, it is contraindicated in individuals with severe kidney impairment.

D. Incorrect. While ciprofloxacin and other antibiotics may have renal-related side effects, they are not a common cause of intrinsic acute renal failure.

A. Incorrect. A complete blood count (CBC. provides information about the number and types of blood cells but does not assess kidney function.

B. Correct. Serum creatinine level is a commonly used blood test to assess kidney function. Elevated levels of creatinine in the blood indicate impaired glomerular filtration and decreased kidney function.

C. Incorrect. Urinalysis provides information about the presence of substances such as protein, blood, and glucose in the urine but does not directly assess GFR.

D. Incorrect. Renal ultrasound is an imaging test that provides information about the structure of the kidneys but does not directly measure GFR.
