- A. They have a high energy-to-fluid-volume ratio.
- B. Even though hypertonic, they are well tolerated.
- C. They are a basic solution secondary to the addition of sodium hydroxide (NaOH).

Correct Answer: A
Rationale: They 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. A milliliter of 5% dextrose only supplies 0.17 kilocalories. Choices 2, 3, and 4 are incorrect because fat emulsions are essentially pH neutral and isotonic.
