NURS 6550 FINAL EXAM – WALDEN UNIVERSITY SUMMER 2019(UPDATED) 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 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-surgicalrhabdomyolysis 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 levelsrange from 0.6mg/dl to 1.2mg/dl. Thus, the most likely differential is: Post-surgical rhabdomyolysis causing intrarenal failure. 1 points QUESTION 2 1.
