Ans: C
TPN is a highly concentrated solution of carbohydrates, electrolytes, vitamins, and minerals. TPN provides all nutrients to meet a child's needs. It is delivered via central venous access to allow rapid dilution of hypertonic solution. It is usually used in a child with a nonfunctioning gastrointestinal (GI) tract, such as a congenital or acquired GI disorder; a child with severe failure to thrive or multisystem trauma or organ involvement; and preterm newborns.
