NU317 Exam 4 With
Correct Answers
Three functions of kidneys - ANSWER urine formation, electrolyte/ BP
balance, production of erythropoietin
s/s of AKI - ANSWER decreased urine output, swelling in legs ankles and
around eyes, fatigue, SOB, confusion, nausea, chest pain or pressure, and
seizures/ coma in severe cases
meds that affect kidney fxn - ANSWER NSAIDs, ARBs/ ACEi, diuretics, MRAs,
metformin, antibiotics (ex: vancomycin)
AKI anuric UOP - ANSWER less than 100 mL per day
AKI oliguric UOP - ANSWER less than 500 mL per day
AKI non-oliguric UOP - ANSWER more than 500 mL per day
what is a vital sign that may indicate that kidneys aren't profusing - ANSWER
orthostatic vitals
, pre-renal AKI - ANSWER hypovolemic states, hypervolemic states,
hypotension, dysregulation of renal vasculature
acute glomerulonephritis - ANSWER hematuria, proteinurea, HTN, pyuria,
hypoalbuminemia, edema, HLD
acute tubular necrosis - ANSWER most common cause of AKI; often caused
by prolonged or severe ischemia or nephrotoxic exposure; can be associated
with sepsis or shock, oliguria, inability to concentrate urine
specific gravity levels - ANSWER 1.005 dilute to 1.030 concentrated
acute interstitial nephritis - ANSWER often drug-induced, sterile pyuria,
classic triad (fever, rash, and serum eosinophilia)
renal vascular disease - ANSWER Impaired blood flow and renal ischemia
activate the Renin-angiotensin-aldosterone mechanism in an effort to raise
renal perfusion pressure
Post-renal AKI causes - ANSWER Secondary to obstruction of urinary outflow
Usually no kidney damage
