Question 1 of 5
Fat emulsions are frequently administered as a part of total parenteral nutrition. Which statement is true regarding fat emulsions?
Correct Answer: A
Rationale: The correct statement is that fat emulsions have a high energy-to-fluid-volume ratio. Fat emulsions are formulated in 10%, 20%, and 30% solutions and supply 1.1, 2, and 3 kilocalories, respectively, for each milliliter. In comparison, a milliliter of 5% dextrose only supplies 0.17 kilocalories.
Choices B, C, and D are incorrect.
Choice B is false because fat emulsions are essentially pH neutral and isotonic, not hypertonic.
Choice C is incorrect because fat emulsions are not basic solutions; they are essentially pH neutral.
Choice D is incorrect as fat emulsions are not alkaline; they are pH neutral, making them compatible with most medications.
