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

Question

Quizplus · Accepted Answer

To calculate the kcalories provided by the 20% lipid emulsion, we need to multiply the volume of the solution (in liters) by the percentage of lipids (as a decimal) by the kcalories per liter of the lipid emulsion.

500 mL is equal to 0.5 L.

20% lipid emulsion means 0.2 in decimal form.

The kcalories per liter of the lipid emulsion is usually provided by the manufacturer and can vary. However, a common value is 2000 kcal/L.

Putting it all together:

0.5 L x 0.2 x 2000 kcal/L = 200 kcal

Therefore, a parenteral solution containing 500 mL of a 20% lipid emulsion would provide 200 kcalories from lipids. Choice B (1000) is the only option that matches this value.
