Which statement is true regarding GI losses for HPN coverage?

Which statement is true regarding GI losses for HPN coverage?

• A. GI losses exceeding 50% of oral intake (2.5-3 L/day in and >1.25-1.5 L/day out)
• B. GI losses must be exactly 50% of oral intake
• C. GI losses must be less than 50% of oral intake
• D. GI losses are not considered in HPN coverage

Answer: (A)

The concept to grasp is that parenteral nutrition is considered when GI losses are large enough that oral/enteral intake cannot meet fluid, electrolyte, and energy needs. When GI losses exceed half of what the patient can take by mouth, the deficit becomes too great to rely on oral intake alone. That level of loss typically corresponds to substantial daily losses and necessitates providing calories, protein, fluids, and electrolytes intravenously through PN while the GI tract cannot absorb enough. So, stating that GI losses exceeding 50% of oral intake (about 2.5–3 L/day in, with losses over roughly 1.25–1.5 L/day out) warrant HPN coverage reflects this threshold. The other options don’t fit because they imply the losses must be exactly 50%, must be less than 50%, or are not considered—none of which align with how high GI losses drive the need for parenteral support.
