When making 2-in-1 parenteral nutrition, the pharmacy uses D50% w/v. How many milliliters of D50% are required to prepare LB's parenteral nutrition order?

Answer :

Final answer:

To provide 370 grams of dextrose in a 2-in-1 parenteral nutrition order using D50%, 740 mL of D50% solution is required.

Explanation:

To calculate how many milliliters of D50% (which is a 50% dextrose solution) are needed to provide 370 grams of dextrose, we use the following steps:

Firstly, determine the concentration of dextrose in the D50% solution. Since it's a 50% solution, this means there are 50 grams of dextrose per 100 mL of solution.

Next, calculate the total volume of D50% needed to provide the prescribed amount of dextrose: (370 grams) ÷ (50 grams/100 mL) = 740 mL of D50%

This calculation assumes that the density of the D50% solution is such that 1 mL of solution contains 0.5 grams of dextrose, which is typical for parenteral nutrition preparations.
