Isosource HN and Fibersource HN are examples of which type of tube-feeding formulas?

• A. High nitrogen formulas
• B. Semi-elemental formulas
• C. Blenderized formulas
• D. Standard polymeric formulas

Answer: (A)

The key idea is protein content per serving. Isosource HN and Fibersource HN are designed to deliver more protein, i.e., more nitrogen, to meet increased needs for tissue repair and recovery in stressed or healing patients. The “HN” in their names signals high nitrogen, distinguishing them from standard formulas with typical protein levels. They’re still polymeric formulas (intact protein), not semi-elemental or blenderized, but the defining feature here is the elevated protein—and thus nitrogen—content. This is why they’re classified as high nitrogen formulas.
