Q

What are advantages and disadvantages to tube enterostomies?

A

  • Tubes must be placed by physician or sugeon
24
Q

What are advantages and disadvantages to a gastrostomy?

A
  • Feedings can be given intermittently and w/o a pump

- Moderate risk of aspiration

25
What are advantages and disadvantages to a jejunostomy?
- Lowest risk of aspiration | - Most difficult insertion process
26
When are standard enteral formulas used?
Individuals who can digest and absorb nutrients w/o difficulty
27
What do standard enteral formulas contain?
- Intact proteins extracted from milk or soybeans | - Carbohydrate sources from hydrolyzed corn starch, glucose polymers, and sugars
28
What are other names for elemental formulas?
- Hydrolyzed - Chemically defined - Monomeric
29
When are elemental enteral formulas used?
Patients who have compromised digestive or absorptive functions
30
What do elemental enteral formulas contain?
Proteins and carbs that have been partially or fully broken down that require little, if any, digestion
31
When are specialized enteral formulas used?
Patients w/ particular illnesses w/ specific nutrient needs
32
When are modular enteral formulas used?
Patients who require specific nutrient combinations to treat illnesses
33
When are intermittent feedings best tolerated?
When delivered into the stomach
34
What is bolus feeding?
Rapid delivery of a large volume of formula into the stomach (250-500 mL over 5-15 mins)
35
What are advantages to bolus feeding?
- Convenient for patient and staff | - Allow greater independence of patients
36
What are disadvantages to bolus feeding?
- Can cause abdominal discomfort, nausea, and cramping | - Risk of aspiration is higher
37
When is bolus feeding used?
For patients who are not critically ill
38
What are continuous feedings?
Delivered slowly and at a constant rate over 8-24 hours
39
When are continuous feedings used?
Critically ill patients b/c slower delivery is easier to tolerate
40
What are disadvantages to continuous feedings?
- Limit patient's freedom of movement | - More costly
41
What are contraindications to parenteral nutrition?
- GI tract is functioning and accessible - Short-term treatment anticipated (less than 7 days) - Risks outweigh benefits - Palliative care - Patient not stable - Inability to obtain venous access
42
Who is parenteral nutrition used for?
Patients who are unable to digest or absorb nutrients and who are either malnourished or likely to be
43
What is peripheral parenteral nutrition?
- Nutrients delivered using only peripheral veins - Used short term (7-14 days) - Solutions must be less concentrated to prevent damage to peripheral veins, so higher volumes are needed
44
What is central peripheral nutrition?
- Aka total parenteral nutrition - Nutrients are delivered using the central veins located near the heart - Used longer term - Solutions can be more concentrated, so volume is lower
45
What is 2-in-1 parenteral solution?
Contains dextrose and amino acids; lipid emulsion is administered separately
46
What is 3-in-1 parenteral solution?
Contains dextrose, amino acids, and lipids
47
How can parenteral nutrition be administered?
- Continuously (24-hour period) | - Cyclic (8-16 hour period)
48
When can refeeding syndrome occur?
When feedings are overly aggressive for severely malnourished individuals
49
What are symptoms of refeeding syndrome?
- Fluid and electrolyte imbalance | - Hyperglycemia
50
What is dysphagia?
Difficulty swallowing
51
What are symptoms of dysphagia?
- Drooling - Choking or coughing during or after meals - Pocketing food - Absent gag reflex - Inability to suck on straw - Chronic upper respiratory infections
52
What does oropharyngeal dysphagia inhibit?
Transfer of food from mouth and pharynx to esophagus
53
What does esophageal dysphagia inhibit?
Passage of materials through esophageal lumen and into stomach
54
What usually causes esophageal dysphagia?
Obstruction in esophagus or motility disorder
55
What are some complications w/ dysphagia?
- Aspiration - Dehydration - Loss of enjoyment for eating - Weight loss
56
What is the difference between a soft diet and soft/minced diet?
- Both are a standard diet modified w/ soft to chew foods | - Soft/minced includes some plain minced meats when soft textured meat is not suitable
