  1. Which macronutrient in total parenteral nutrition (TPN) is the PRIMARY energy source and contributes 3.4 kcal per gram?

    Answer: Dextrose

    Dextrose (glucose) in parenteral nutrition provides 3.4 kcal/g and is the primary carbohydrate energy substrate.

  2. What is the caloric density of a standard 20% lipid emulsion used in parenteral nutrition?

    Answer: 2.0 kcal/mL

    A 20% lipid emulsion provides 2.0 kcal/mL, making it a calorie-dense component of TPN formulations.

  3. Which of the following electrolytes must be separated from calcium in TPN admixtures to avoid precipitation?

    Answer: Phosphate

    Calcium and phosphate can form calcium phosphate precipitate, a dangerous incompatibility in TPN admixtures.

  4. What type of filter is recommended when administering a total parenteral nutrition solution that does NOT contain lipid emulsion?

    Answer: 0.22-micron filter

    A 0.22-micron filter is used for lipid-free TPN to remove particulates and microorganisms during administration.

  5. Which filter pore size is appropriate for administering a total nutrient admixture (3-in-1 TPN containing lipids)?

    Answer: 1.2 micron

    A 1.2-micron filter is used for 3-in-1 TPN to allow lipid droplets to pass through while removing larger particulates.

  6. What is the recommended order of addition when compounding a TPN admixture to minimize calcium-phosphate precipitation?

    Answer: Calcium last, phosphate first

    Phosphate should be added first and diluted well before calcium is added last, minimizing localized precipitation risk.
