Final answer:
In the case of acute kidney failure, the expected biochemical findings are increased levels of blood urea nitrogen (BUN) and creatinine due to reduced kidney filtration. Symptoms and complications include uremia, fluid imbalances, and electrolyte disturbances.
Step-by-step explanation:
The expected biochemical findings in the blood for acute kidney failure are increased blood urea nitrogen (BUN) and creatinine. Acute kidney failure, also known as acute renal failure, leads to a decrease in the glomerular filtration rate, which results in the accumulation of waste products in the blood. Among these waste products are BUN and creatinine, which are commonly measured to assess kidney function.
Analyses typically reveal an elevated serum creatinine, indicating a reduction in the kidneys' ability to filter and dispose of creatinine. Elevated levels of BUN additionally point to the kidneys' failing role in filtering urea from the blood. Conversely, acute kidney failure does not typically result in elevated sodium levels or decreased potassium levels; in fact, potassium levels may actually rise due to decreased excretion by the kidneys.
