2. hypovolemia
3. sepsis

1. acute proliferative glomerulonephritis
2. nothing because these tests are within normal limits

Answer to Question 1

Correct Answer: 1
Causes for postrenal AKI include calculi, cancer, external compression, benign prostatic hypertrophy, strictures, and blood clots. Hypovolemia, sepsis, and drug toxicity would be considered prerenal causes of AKI.

Answer to Question 2

Correct Answer: 1

Acute poststreptococcal glomerulonephritis (also called acute proliferative glomerulonephritis) is the most common primary glomerular disorder and is identified by a throat culture that detects group A beta-hemolytic streptococci. The ASO titer detects streptococcal exoenzymes which are present in poststreptococcal proliferative glomerulonephritis. The urinalysis also demonstrates the presence of protein, red blood cells, and white blood cells which are typical with this condition. Serum creatinine and BUN elevations are consistent with glomerulonephritis. Prerenal AKI is typically caused by hypovolemia or low cardiac output and none of the laboratory test results validate this finding. End-stage kidney disease is classified by the glomerular filtration rate, which is not noted in the laboratory report. These tests are not within normal limits.
