Pre operative meds correct answers Cephalosporin
Methylprednisolone
Sometimes Tacro or cellcept
signs of acute tubular necrosis correct answers Death of kidney tubular cells that
transport urine to ureters
Anuria
Increased BUN/Cr
Decreased GFR
Hyper electrolytes
What to do if ATN is expected correct answers give thymoglobulin or other induction

Maintain acid base balance
Activate vitamin D
ATN treatment correct answers there is no treatment, wait it out it can last days to
weeks
Monitor for electrolyte abnormalities or major fluid overload
Enteric drainage vs bladder drainage correct answers enteric has less risk for
fluid/electrolyte changes post transplant
