Final answer:
Renal failure is often characterized by elevated levels of blood urea nitrogen (BUN) and creatinine. Therefore, the most consistent findings with renal failure are High BUN and High Creatinine, which corresponds to option A.
Step-by-step explanation:
Renal failure is often characterized by elevated levels of blood urea nitrogen (BUN) and creatinine. Therefore, the most consistent findings with renal failure are High BUN and High Creatinine, which corresponds to option A. BUN and creatinine are markers of kidney function, and when the kidneys are not functioning properly, these levels can increase. In renal failure, the kidneys are unable to effectively remove waste products from the body, leading to elevated levels of BUN and creatinine in the blood.
