Incorrect. The liver produces waste products like ammonia, but elevated BUN and creatinine levels are primarily related to kidney dysfunction, not increased production by the liver.
Incorrect. Decreased reabsorption of waste products by the renal tubules can contribute to elevated levels, but the primary issue in acute renal failure is impaired filtration and excretion.
