The nurse should recognize that the findings in the Electronic Medical Records are consistent with acute glomerulonephritis as evidenced by which of the following?

Choice A rationale Urinalysis findings in acute glomerulonephritis typically reveal a high specific gravity due to concentrated urine resulting from the kidneys' attempt to conserve fluid in the presence of decreased glomerular filtration. Low specific gravity, on the other hand, is a finding more consistent with conditions like diabetes insipidus, chronic renal failure, or overhydration, where the renal tubules have impaired concentrating ability. A specific gravity of 1.010 to 1.030 is considered normal. Choice B rationale Acute glomerulonephritis is characterized by increased glomerular capillary permeability, allowing larger molecules like protein to leak into the urine. This results in significant proteinuria, which is a key diagnostic finding. Decreased protein levels in the urine would be considered a normal finding, or a finding in conditions without glomerular damage, and would therefore not be consistent with a diagnosis of acute glomerulonephritis. Normal urine protein is less than 150 mg/24 hours. Choice C rationale Red blood cell casts are a definitive microscopic finding in acute glomerulonephritis and are formed when red blood cells aggregate in the renal tubules and are molded into a cylindrical shape by the Tamm-Horsfall protein. Their presence confirms a glomerular origin of the hematuria and is a specific indicator of an active inflammatory process within the glomeruli. This finding is highly specific to glomerulonephritis. Choice D rationale The urine pH in acute glomerulonephritis is typically acidic, with a normal range of 4.5 to 8.0. A pH of 8.0 is at the upper end of the normal range and could indicate an alkaline state, which is more commonly associated with conditions like urinary tract infections caused by urease-producing bacteria, or a vegetarian diet, rather than the inflammatory process of acute glomerulonephritis.
