What happens to the kidneys during diabetes mellitus?
The kidneys are damaged by glomerularsclerosis and nephrosclerosis scarring (afferent or efferent arterioles)
What symptoms manifest with diabetes mellitus and kidneys?
Increase of protein in the urine, edema, high blood pressure, and renal failure.
What is the relationship between kidneys and insulin?
The kidneys metabolize insulin, and when they are so damaged, the metabolization of it also declines. This results in a lower insulin requirement.

Why do serum urea nitrogen and creatnine levels decrease with kidney failure?
The kidney cannot filter as it once could and the GFR is reduced and clearance as well. This results in an excess that enters the blood instead of being excreted.
What occurs with surviving nephrons in chronic renal failure?
They remaining nephrons hypertrophy from so much added stress from solutes and the kidneys cannot concentrate urine adequately.
Why do some clients suffer from fluid depletion with chronic kidney failure?
They can't concentrate their urine, so a large amount of fluid is passed to try to help excrete the solutes.
What is wrong with the tubules in chronic renal failure?
They lose their ability to reabsorb electrolytes..usually sodium...which makes it numerous in urine. As time progresses, the body loses lots of fluid as well, and renal damage increases. The number of nephrons decline, and the kidneys cannot get rid of excess water salt and other waste products.
