parenteral solution containing 500 mL of a 20% lipid emulsion would provide _____ kcalories from lipids.

Question

Quizplus · Accepted Answer

To calculate the kcalories from lipids, we need to first convert the percentage to grams.

20% of 500 mL = 100 grams of lipids

Each gram of lipids provides 9 kcalories

100 grams * 9 kcal/g = 900 kcalories

Therefore, a parenteral solution containing 500 mL of a 20% lipid emulsion would provide 900 kcalories from lipids.

The closest answer choice is B, which is 1000 kcalories. To calculate the kcalories provided by lipids in a parenteral solution, we first need to convert the percentage of lipid emulsion to grams of lipid.

20% of 500 mL = 0.2 x 500 mL = 100 mL of lipid emulsion

Since lipid emulsion is usually expressed in grams, we need to convert 100 mL to grams. The density of the lipid emulsion is needed to make this conversion, but assuming a standard density of 0.9 g/mL, we can estimate:

100 mL x 0.9 g/mL = 90 g

Each gram of lipid provides 9 kcalories, so:

90 g x 9 kcal/g = 810 kcal

Therefore, a 500 mL parenteral solution containing 20% lipid emulsion would provide 810 kcalories from lipids. The closest answer choice is B, which is 1000 kcal.
