When is TPN indicated for a patient's nutritional support?
When is TPN indicated for a patient's nutritional support?
- When the patient is able to fully digest nutrients through the GI tract.
- When the patient can ingest only solid foods.
- When the patient's nutritional needs cannot be met through oral or tube feedings. (correct)
- When the patient requires short-term nutritional supplementation.
What is a key difference between administering TPN through a peripheral IV versus a central line?
What is a key difference between administering TPN through a peripheral IV versus a central line?
- Peripheral IV lines are ideally short term with less concentrated solutions, while central lines are long term with highly concentrated solutions. (correct)
- Peripheral IV lines use highly concentrated solutions, while central lines use less concentrated solutions.
- Peripheral IV lines are suitable for long-term TPN administration, while central lines are for short-term use.
- Peripheral IV lines require dedicated lines to prevent thrombophlebitis, unlike central lines.

Study Notes
- TPN, aka "Total Parenteral Nutrition", is a form of IV therapy
- TPN supplies the patient with essential nutrients
- TPN is used when the patient cannot ingest any oral or tube feedings
- TPN is used when nutritional needs cannot be met by I.V. solutions
Examples of when to use TPN
- Disorders of the GI tract.
- Excessive metabolic needs.
- Prolonged chemotherapy or radiation therapy.
Delivery Methods
- Peripheral IV for ideally short term (less than 10 days) and less concentrated solutions
- Central Line for long term use, high concentrated solutions; uses larger vessels to prevent thrombophlebitis
- Use Dedicated IV line
TPN Contents
- Carbohydrates (dextrose)
- Amino Acids
- Electrolytes
- Fat Emulsions
- Vitamins
- Trace Elements
- Medications (ex: Heparin to prevent clotting at catheter tip)
Potential Complications
- Hyperglycemia (monitor blood sugar).
- Hypoglycemia (if shut off without weaning).
- Infection (watch for signs of central line infection).
- Air Embolism.
- Fluid Overload (refeeding syndrome).
