TPN, PPN, and Tube Feeding Techniques

A set of flashcards covering concepts related to Total Parenteral Nutrition, Partial Parenteral Nutrition, tube feeding methods, and blood glucose monitoring.

Total Parenteral Nutrition (TPN)

A method of delivering nutrition directly into the bloodstream via a central line, used when the digestive system is not functioning properly.

Partial Parenteral Nutrition (PPN)

A method of providing nutrition through a peripheral vein, generally containing lower concentrations of dextrose compared to TPN.

Enteral Feeding

Providing nutrition to patients via the gastrointestinal tract through methods such as tubes.

Gastrostomy Tube (G-Tube)

A tube inserted into the stomach for long-term feeding, often used in patients who have difficulty swallowing.

Jejunostomy Tube (J-Tube)

A tube placed in the jejunum (part of the small intestine) for feeding, indicated for patients with stomach issues.

Aseptic Technique

A practice used to prevent contamination and infection during the administration of nutritional feeds.

pH Testing for NG Tube Placement

A method to confirm the placement of a nasogastric tube by checking the acidity of gastric contents.

Residuals in Tube Feeding

A measure of undigested formula remaining in the stomach, indicating how well the patient is tolerating the feeds.

Bolus Feeding

A method of enteral feeding where a large volume of feed is given all at once, resembling regular meal patterns.

Continuous Feeding

A method of enteral feeding where nutrition is provided over a prolonged period, ensuring constant caloric intake.

Hyperglycemia

A condition characterized by high blood sugar levels, often monitored in diabetic patients.

Hypoglycemia

A state of low blood sugar which can cause symptoms such as sweating, dizziness, and confusion.

Infusion Pump Calculation

The method of determining the rate of feed administration based on total volume and time required for the feeding.
