4. These are signs of a genetic renal disorder.
Correct Answer: 1
Typical age-related changes of the renal system include a decreased size of the renal cortex, atherosclerosis of the renal arteries, and hypo-osmolality. Because of the patient's age, the patient most likely is not experiencing chronic or acute renal failure or evidence of a genetic kidney problem.
