Question

What substances are not commonly found in a TPN?

1) Lipids
2) Dextrose
3) Antibiotics
4) Amino acids

Answer 1

Lipids and antibiotics are substances not commonly found in a TPN solution. Dextrose and amino acids are commonly included in a TPN solution.

Step-by-step explanation:

In a total parenteral nutrition (TPN) solution, the substances that are not commonly found are:

1. Lipids: TPN solutions may not contain lipids or fats. Lipids are typically administered separately as an intravenous fat emulsion.
2. Antibiotics: While TPN solutions can contain certain medications, antibiotics are not typically included in the TPN formulation. Antibiotics are typically administered separately, if needed.

On the other hand, the TPN solution commonly includes:

1. Dextrose: Dextrose, a form of sugar, is a critical component of TPN that provides carbohydrates for energy.
2. Amino acids: Amino acids are the building blocks of proteins and are essential for tissue repair and growth.
