B) "I am glad you noticed this change. It happened so gradually that we did not see it. We should call the doctor and get him to measure ADH."
C) "His renal tubules are recovering, so he is making more urine, but he is not able to concentrate urine well, because he is not fully recovered."
D) "We had better measure his blood sugar. He may have developed diabetes, and what you see is osmotic diuresis from glucose in the urine."
