CSPT CSPT - Compounded Sterile Preparation Technician Parenteral Nutrition and IV Admixture Preparation Questions and Answers 1

Question 1

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

Accepted Answer

Dextrose

Answer

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

Question 2

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

Accepted Answer

2.0 kcal/mL

Answer

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

Question 3

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

Accepted Answer

Phosphate

Answer

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

Question 4

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

Accepted Answer

0.22-micron filter

Answer

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

Question 5

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

Accepted Answer

1.2 micron

Answer

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