The nurse is caring for a client diagnosed with ARF. Which laboratory values are most significant for diagnosing ARF?
Correct answer
A
Rationale
Elevated blood urea nitrogen (BUN) and creatinine levels indicate impaired kidney function, making them the primary markers for diagnosing ARF. Other labs like WBC, electrolytes, or liver function tests are less specific for ARF diagnosis.
