QUESTION 1
1. Mr. Jeffers was admitted 2 days ago for a carotid endarterectomy. A Foley catheter was inserted
intraoperatively and remains in place. His
... [Show More] urine output has declined markedly despite continued IV fluid
infusion. Today his morning labs reveal a BUN of 19 mg/dL and a creatinine of 2 mg/dL. A leading
differential includes:
A. Foley lodged in the urethra causing post-renal failure
B. Decreased renal perfusion causing prerenal failure
C. Age-related decreased eGFR causing prerenal failure
D. Post-surgical rhabdomyolysis causing intrarenal failure
Answer:
D. Post-surgical rhabdomyolysis causing intrarenal failure
During surgery, muscles and injured. This can result into rhabdomyolysis, which is the breakdown of
muscles to release proteins. The excess proteins causes an increased level of creatinine.
Mr. Jeffers is from surgery (post-surgical) and his creatinine levels are above normal. The normal
creatinine levels range from 0.6mg/dl to 1.2mg/dl. Thus, the most likely differential is: Post-surgical
rhabdomyolysis causing intrarenal failure.
