Common complication of parenteral nutrition?
Infections, particularly catheter-related bloodstream infections.
True or False: Both enteral and parenteral nutrition can provide complete nutrition.
True. Both can supply necessary calories and nutrients for patients.
What is a disadvantage of enteral nutrition?
Risk of aspiration if not properly monitored.
What should be monitored in parenteral nutrition?
Electrolyte levels, liver function, and infection signs.
Clinical Considerations(12)
What are key complications of enteral nutrition?
- Aspiration pneumonia - Diarrhea - Constipation - Tube obstruction - Gastrointestinal intolerance
True or False: Parenteral nutrition can cause liver complications.
True. It can lead to liver dysfunction due to factors like prolonged use and lack of enteral stimulation.
Fill in the blank: Enteral nutrition is administered via ______.
nasogastric tube, gastrostomy, or jejunostomy.
How does enteral nutrition benefit patients?
- Maintains gut integrity - Supports immune function - Reduces infection risk - Cost-effective compared to parenteral nutrition.
What is a common complication of parenteral nutrition?
- Catheter-related infections (CRBSI)
True or False: Enteral nutrition can cause aspiration pneumonia.
True. Aspiration pneumonia can occur if enteral feedings are not properly managed, particularly if the patient has impaired swallowing or altered consciousness.

Fill in the blank: Parenteral nutrition is often administered through ______.
a central venous catheter (CVC).
