Which element indicates the formulation type, such as TNA versus dextrose/amino acids and separate IVFE?

• A. Type of formulation
• B. Route of administration
• C. Infusion duration
• D. Patient ID

Answer: (A)

Understanding how parenteral nutrition is organized tells you how the nutrients are packaged. A total nutrient admixture (TNA) is a single bag that already contains dextrose, amino acids, and IV fat emulsion, while a different approach uses dextrose and amino acids in one bag with IV fat emulsion supplied separately. The route of administration, infusion duration, or patient identifiers don’t determine the formulation style—they deal with how the therapy is delivered or tracked. Therefore, the element that indicates the formulation type is the type of formulation itself.
