Which option refers to parenteral nutrition acronyms as described in the material?

• A. TPN
• B. TNA
• C. PMN
• D. Two of the above

Answer: (D)

Recognizing common acronyms used in parenteral nutrition helps you read notes and orders more quickly. Total Parenteral Nutrition is the standard term for delivering all daily nutrients intravenously. Total Nutrient Admixture is another term you may see, referring to the complete nutrient solution prepared as a single admixture for infusion. PMN isn’t a parenteral nutrition acronym, so it doesn’t belong in this context. Since two of the terms describe parenteral nutrition, the correct interpretation is that two of the listed acronyms refer to parenteral nutrition.
