A client is started on peripheral parenteral nutrition. The nurse asks the nursing student to explain the difference in a preclinical conference between peripheral parenteral nutrition and total parenteral nutrition
What information did the student nurse correctly state about peripheral parenteral nutrition? A) Used when the gastrointestinal tract is functioning improperly
B) Infused directly into the blood circulation
C) Surgically placed into the central vein near the heart to allow the concentrated solution to be diffused quickly into circulation
D) Infusions must be hypotonic or isotonic to prevent dehydration and electrolyte imbalance
D
Feedback:
Infusions given peripherally must be hypotonic or isotonic (to prevent dehydration and electrolyte imbalance). Total parenteral nutrition is used when the gastrointestinal tract is functioning improperly, such as in stomach cancer, or when a person has multiple trauma, severe infection, burns, or multiorgan failure. TPN is infused directly into the blood circulation and bypasses the digestive tract. Several types of catheters (tubes) are used. The large catheter is surgically placed into the central vein near the heart to allow the concentrated solution to be diffused quickly into the circulation.
