Best Answer

TOTAL parenteral nutrition (TPN) provides 100% of the body's nutrient requirements when the patient is unable to tolerate, absorb or accumulate sufficient nutrients by mouth or an enteral route.

PARTIAL parenteral nutrition (PPN) provides SOME of the body's nutrient requirements and is an adjunct to other nutrition.

TPN must be administered by a central IV route, whereas PPN may be administered by either a central or peripheral IV route.
