Here is how the Blood Urea Nitrogen using Calculated Serum Osmolality equation looks like.

7.5071 = 2.8 \cdot ((40) - (2 \cdot 0.0009) - (\frac{20.5}{18}))

7.5071mg/dL = 2.8 \cdot ((40mmol/kg) - (2 \cdot 0.0009mmol/L) - (\frac{20.5mg/dL}{18}))

7.5071 = 2.8 \cdot ((40) - (2 \cdot 0.0009) - (\frac{20.5}{18}))

Blood Urea Nitrogen using Calculated Serum Osmolality Solution

Follow our step by step solution on how to calculate Blood Urea Nitrogen using Calculated Serum Osmolality?

FIRST Step Consider the formula

BUN = 2.8 \cdot ((O serum) - (2 \cdot [Na] serum) - (\frac{G serum}{18}))

Next Step Substitute values of Variables

∴

BUN = 2.8 \cdot ((40mmol/kg) - (2 \cdot 0.0009mmol/L) - (\frac{20.5mg/dL}{18}))

Next Step Convert Units

∴

BUN = 2.8 \cdot ((0.04mol/kg) - (2 \cdot 0.0009mol/m³) - (\frac{0.205kg/m³}{18}))

Next Step Prepare to Evaluate

∴

BUN = 2.8 \cdot ((0.04) - (2 \cdot 0.0009) - (\frac{0.205}{18}))

Next Step Evaluate

∴

BUN = 0.0750711111111111kg/m³

Next Step Convert to Output's Unit

∴

BUN = 7.50711111111111mg/dL

LAST Step Rounding Answer

∴

BUN = 7.5071mg/dL
