Parenteral Nutrition Practice questions for all type of Exams. 15 questions are here for your assessment.

Parenteral nutrition, also known as intravenous feeding, is a method of getting nutrition into the body through the veins. While it is most commonly referred to as total parenteral nutrition (TPN), some patients need to get only certain types of nutrients intravenously. Parenteral nutrition is often used for patients with Crohn’s disease, cancer, short bowel syndrome, and ischemic bowel disease.


Parenteral Nutrition (PN) Practice questions




Administration of PN

Central vein Administration Procedure

  • PN is administered through a central vein when the client requires a larger concentration of carbohydrates (greater than 10% glucose concentration).
  • The subclavian or internal jugular vein is the central vein normally used when PN is a short-term intervention (less than 4 weeks).
  • When PN is anticipated for an extended period (longer than 4 weeks), a more permanent catheter, such as a peripherally inserted central catheter (PICC) line, a tunneled catheter, or an implanted vascular access device, is used.

Peripheral vein (PN)

  • PN can be administered through a peripheral vein, typically in the arm, via a PICC line.
  • PN administered through a peripheral vein delivers isotonic or mildly hypertonic solutions.
