Amount in IV Fluid Questions
Given a volume of IV fluid and a dosage expressed in percent, what is the mass of a particular dosage?

Formula:

$\overline{)\frac{{\mathbf{Concentration %}}}{{\mathbf{100}}}x{\mathbf{Volume \left(mL\right)}}={\mathbf{Y\left(Dosage Amount in g\right)}}}$

Example: Calculate the amount of dextrose in 1000 mL D5W.
$\frac{{\mathbf{Concentration %}}}{{\mathbf{100}}}x{\mathbf{Volume \left(mL\right)}}={\mathbf{Y\left(Dosage Amount in g\right)}}$
$\frac{{\mathbf{5 %}}}{{\mathbf{100}}}x{\mathbf{1000 mL}}=\overline{){\mathbf{50 g}}}$

Example: Calculate the amount of sodium chloride in 2000 mL NS.
Recall NS is 0.9% NaCl (sodium chloride)

$\frac{{\mathbf{Concentration %}}}{{\mathbf{100}}}x{\mathbf{Volume \left(mL\right)}}={\mathbf{Y\left(Dosage Amount in g\right)}}$
$\frac{{\mathbf{0.9 %}}}{{\mathbf{100}}}x{\mathbf{2000 mL}}=\overline{){\mathbf{18 g}}}$
