NAPLEX (North American Pharmacist Licensure Examination) Practice Exam

What is the kcal/gram value for Dextrose monohydrate in parenteral nutrition?

1. 3.4 kcal/gram

2. 4 kcal/gram

3. 9 kcal/gram

4. 1.1 kcal/mL

The correct answer is: 3.4 kcal/gram

Dextrose monohydrate, a form of glucose used in parenteral nutrition, has a kcal/gram value of 3.4. This is because dextrose provides 3.4 kilocalories of energy per gram when metabolized in the body. It is important to note this value as it plays a crucial role in calculating the total caloric content of parenteral nutrition solutions accurately. Option B (4 kcal/gram) is incorrect because the kcal/gram value for dextrose monohydrate is 3.4, not 4. Option C (9 kcal/gram) is incorrect as this value is significantly higher than the actual kcal/gram value of dextrose monohydrate. Option D (1.1 kcal/mL) is incorrect because it provides information on kcal per milliliter, which is not the standard unit used to express the caloric content of dextrose monohydrate in parenteral nutrition. The typical unit used for expressing energy from macronutrients like dextrose is kcal/gram.
