Which option correctly indicates that more than one acronym refers to parenteral nutrition within the list?

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

Answer: (D)

The idea tested is recognizing multiple acronyms used for parenteral nutrition in the list. TPN stands for total parenteral nutrition, a standard term for delivering nutrition intravenously. TNA stands for total nutrient admixture, which is another way people refer to a PN solution when all nutrients are combined in one bag. PMN does not relate to parenteral nutrition; it typically means polymorphonuclear leukocytes, a type of white blood cell. Since both TPN and TNA refer to parenteral nutrition, two items in the list match PN, so the choice that states two of the above refer to parenteral nutrition is correct.
