Fundamentals of Nursing Q 237
A patient receiving parenteral nutrition is administered via the following routes except:
A. Subclavian line.
B. Central Venous Catheter.
C. PICC (Peripherally inserted central catheter) line.
D. PEG tube.
Correct Answer: D. PEG tube.
Percutaneous endoscopic gastrostomy (PEG tube) is inserted into a person’s stomach through the abdominal wall that is used to provide a means of feeding when oral intake is not adequate. While parenteral nutrition bypasses the digestive system by the administration to the bloodstream.
Option A: TPN may be administered as peripheral parenteral nutrition (PPN) or via a central line, depending on the components and osmolality. Central veins are usually the veins of choice because there is less risk of thrombophlebitis and vessel damage (Chowdary & Reddy, 2010).
Option B: Parenteral nutrition may be delivered via femoral lines, internal jugular lines, and subclavian vein catheters in the hospital setting. Central access is required for infusions that are toxic to small veins due to medication pH, osmolarity, and volume.
Option C: PICC lines may be used in ambulatory settings or for long-term therapy. It is inserted in the cephalic, basilic, median basilic, or median cephalic veins and threaded into the superior vena cava. It can remain in place for up to 1 year with proper maintenance and without complications.
