Nutrition Tube Feeding Flashcards
Any form of nutrition delivered to GI tract orally or by tube.
Enteral Nutrition
True or False: Can tube feedings be supplemented to general diet or replace oral intake
True. Tube feeding can be a meal replacement
What ways do enteral feeding differ from one another?
Osmolarity, digestibility, calories, viscosity, fat content, fiber content and expense
True or False: Can tube feeding contain predigested proteins.
True
What is the percentage in terms of protein, CHO, Fat for tube feeding?
16% protein 54% CHO 30% Fat
True or False: Do you have to have an intact GI tract to have tube feeding performed?
True. GI tract must be intact. May have a colostomy bag
What are reasons for getting a Enteral Nutrition?
Inability to ingest foods,
Upper GI is impaired or movement of food to small intestine is disrupted
Inability to meet nutritional needs
Inability to ingest enough calories to meet increased metabolic needs
Inability to digest or absorb food
What would be reasons for inability to ingest food?
Oral Cancer, trauma, unconscious, impaired swallowing
What would be a reason to get enteral nutrition got a person who has the inability to digest or absorb food?
Biliary disease, ulceration colitis
What are different formulas for Tube feedings?
Blenderized Milk Based Lactose Free Complete Formulas with predigested nutrients Special; renal & Hapatic
What length is considered short term nutritional support?
Less than four weeks
What are the disadvantages to short term nutritional support?
Risk for aspiration Can not sit up during feedings Dysfunctional gag reflex Gastric stasis GERD
True or False: Nasoenteric Tubes or Nasogastric has multiple lumen?
False. They have one lumen of various sizes ranging from 8-10 French for Adults.
What 2 most common feeding tubes devices require a guide wire for insertion
Dobhoff and Keofeed II
What prevents the tube from retracting up the esophagus?
Tungsten weighted tip
What is the insertion point for Nasogastric insertion
Inserted through the nostrils
What is the order by way which the nasogastric feeding tube is inserted?
nostrils, nasopharynx, stomach
Ture or False: Must you have an intact gag and cough reflex prior to insertion of nasogastric tube?
True
True or False: Nasojejunal tube or shorter than the nasogastric tube?
False. Nasojejunal tube is longer, because it bypasses the stomach and enters the small intestinal.
How long does it take for the nasojejunal tube to pass from the stomach to the intestines?
24 hours
Is the nasogastric tube longer or shorter than a nasojejunal tube?
Nasojejunal tube is longer
Where is the nasojejunal tube inserted?
Into the small intestine
True or False: Could nasojejunal tube be used for patients with high risk for aspiration?
True
What us considered long term for jejunostomy tube?
6-8 weeks
What is the difference between a G tube and J Tube?
G Tube = Gastrostomy in the the stomach
J Tube = Jejunostomy into the small intestine
PEG stands for what?
Percutaneous Endoscopic Gastrostomy
What is a PEJ?
Percutaneous endoscopic jejunostomy
Where is the PEJ tube passed through?
Tube can be passed through either the jejunum or duodenum
True or False: Should tubing be marked while placing the PEJ?
True. Tubing should be marked because it may migrate back into the stomach
A device that is skin level, immersible in water, and can be hidden with clothing?
Low Profile Gastrostomy tube
What are the advantages of tube feeding?
Provides nutrition when oral feeding is not possible
GI integrity is preserved
Intestinal and hepatic metabolism preserved
fat metabolism and lipoprotein synthesis maintain
insulin/glucagon maintained
How often should you check placement for a patient on a PEJ?
Before each feeding
Before administration of medication
If continuous feeding q4-8
when not used usually q shift
How much should you flush tubing with air?
10-20 ml of air
True or False: Does Gastric pH change with feedings and medication being administered?
True
When you are checking for gastric residual. What are you evaluating for?
Absorption of feeding
What is considered a high gastric residual?
200-250ml
How often is Enteral tube feeding given?
Feeding is given over the course of 24 hours
What is the preferred position during enteral feeding?
Sitting upright in fowlers position at least 30 degrees, or slightly elevated right lateral side lying position
How long should the patient sit upright in the position for? after feeding?
Minimum 1 hour
When should feedings be stopped/paused?
Repositioning, respiratory therapy (CPT, suctioning)
When flushing tubing with water, how often should it be flushed and what how much water?
Flushing should be before and after feedings with 60ml of tap or sterile water to prevent clogging
How often should the feeding formula container be changed?
q 24 hours
