Questions and Answers
What is the usual presentation of AKI?
What is the usual presentation of AKI?
- Fluctuating kidney function with inconsistent glomerular filtration and serum creatinine, cystatin C, and BUN levels
- Sudden decline in kidney function with decreased glomerular filtration and increase in serum creatinine, cystatin C, and BUN levels (correct)
- No change in kidney function with stable glomerular filtration and serum creatinine, cystatin C, and BUN levels
- Gradual decline in kidney function with increased glomerular filtration and decrease in serum creatinine, cystatin C, and BUN levels
What is oliguria and its association with AKI?
What is oliguria and its association with AKI?
- Urine output of less than 400 mL per day, often associated with normal plasma BUN and plasma creatinine levels
- Urine output of more than 400 mL per day, often associated with elevated plasma BUN and plasma creatinine levels
- Urine output of less than 400 mL per day, often associated with elevated plasma BUN and plasma creatinine levels (correct)
- Urine output of more than 400 mL per day, often associated with normal plasma BUN and plasma creatinine levels

What is the cause of prerenal acute renal failure?

Study Notes
Acute Kidney Injury (AKI)
- Typical presentation of AKI includes sudden loss of kidney function, often reversible with treatment
- AKI is often asymptomatic, with diagnosis made through laboratory tests
Oliguria and AKI
- Oliguria is a common complication of AKI, characterized by a urine output of less than 400ml/day
- Oliguria is often associated with AKI, as kidney damage can lead to decreased urine production
Prerenal Acute Renal Failure
- Caused by inadequate blood flow to the kidneys, often due to dehydration, bleeding, or cardiac failure
- Reduced perfusion of the kidneys can lead to acute kidney injury
Intrarenal Acute Renal Failure
- Caused by damage to the kidneys themselves, often due to toxins, medications, or ischemia
- Common associations include acute tubular necrosis, glomerulonephritis, and vasculitis
Postrenal Acute Renal Failure
- Caused by obstruction of the urinary tract, often due to kidney stones, tumors, or prostate disease
- Characterized by backpressure damaging the kidneys
Chronic Kidney Disease (CKD)
- A gradual loss of kidney function over time, often due to diabetes, hypertension, or glomerulonephritis
- CKD is often asymptomatic in its early stages
Progression of Chronic Kidney Disease
- Symptomatic changes often become evident in CKD when the glomerular filtration rate (GFR) falls below 30ml/min
- Contributing factors to progression of CKD include hypertension, proteinuria, and anemia
- Alterations seen in CKD include fibrosis, inflammation, and oxidative stress
Erythropoietin Production in CKD
- Erythropoietin production is decreased in CKD, leading to anemia
- Anemia can worsen CKD, as decreased oxygen delivery to the kidneys can accelerate disease progression
