The nurse explains that in the administration of total parenteral nutrition (TPN), options for infusion do not include which of the following?
a. Central venous access device inserted through the jugular vein
b. Peripheral IV catheter in the back of the hand
c. PICC line inserted peripherally and threaded to the subclavian vein
d. Totally implanted ports or external tunneled central venous catheters
B
TPN is usually infused into the central venous circulation because peripheral vessels are too small to dilute the feeding, becoming inflamed. Good options include central venous access devices, PICC lines, tunneled central venous catheters, or implanted ports. A plain peripheral IV in the back of the hand would not be a suitable location.
