25
How can the nurse calm an anxious client prior to tube insertion?
Have client establish hand signal to indicate a pause to facilitate some form of control
26
What are the 7 aspects of the Preintubation assessment?
1. level of consciousness 2. weight 3. bowel sounds 4. abdominal distention 5. integrity of nasal and oral mucosa 6. ability to swallow, cough and gag 7. nausea and vomiting
27
What do assessment serve as?
A baseline for future comparisons
28
Related to the nose, a major goal of the preintubation assessment is?
To establish which nostril is better suited for insertion
29
What excludes a nostril from being used?
Deviated septum, nasal polyps or narrow nasal passage
30
How does a nurse perform tube measurement?
NEX
31
NEX stands for
Nose. Earlobe. Xiphoid
32
What are 3 methods for assessing stomach placement?
1. Fluid aspiration 2. Auscultating the abdomen 3. PH Testing of aspirated liquid
33
Which colors should aspirated gastric fluid be?
Yellow, green, brown
34
What is auscultation of the abdomen?
Instilling 10ml of air into tube, placement of bell over stomach to listen for swoosh sound
35
What is an indicator that tube-end might be in the esophagus?
Belching
36
What are the two types of performed suction?
1. continuous | 2. Intermittent
37
Low pressure suction values are usually between?
40 to 60 mm Hg
38
How can a nurse promote tube patentcy on a client that is NPO?
Providing ice chips or sips of water
39
What is the potential disadvantage of ice chips/ water administration when trying to maintain tube patency?
Water is hypotonic so to much which will draw electrolytes into gastric secretions to be suctioned out
40
Can a nurse perform a tube irrigation?
Not without a medical order
41
Unobstructed larger diameter tubes are usually removed and changed every
2-4 weeks
42
Unobstructed smaller diameter tubes are usually removed and changed every
1-3 months
43
How does the NEX measurement of a nasointestinal tube differ to a nasogastric?
Addition of 9 inches (23 cm)
44
During nasointestinal tube insertion, which syringe is used to aspirate fluid?
50-mL syringe
45
Durring nasointestinal tube insertion, when does the nurse tape the tube to the nose?
When the third mark on the tube is reached
46
Why is a larger syringe perfered to a smaller one for fluid aspiration?
Larger one produces less negative pressure during aspiration and this provides more fluid for testing
47
What are 4 causes for gastrostomy leaks?
1. Clamped G-tube while tube feeding is infusing 2. Mismatch between stoma and G-tube 3. Increased abdominal pressure from formula accumulation, sneezing, coughing 4. Underinflation of balloon beneath the skin
48
Benefit to instilling nutrients into the stomach
Reduction of enteritis (inflammation of intestines) since gastric juices destroys microorgansims
49
Disadvantage to instilling nutrients into the stomach
Increased risk of gastric reflux ( increased volume within stomach)
50
Advantage to intestinally placed tube
Reduced risk of gastric reflux
51
Disadvantage to intestinally placed tube
Dumping syndrome
52
What is Dumping syndrome?
When calorically dense content is placed into intestines, low blood glucose arise because of insulin surge
53
Symptoms of dumping syndrome
Naseua, sweating, weakness, dizziness
54
List 4 activities with gastrostomy management
1. Daily inspection of skin around tube 2. Making sure sutures are in tact 3. Apply skin barrier ointment (zinc oxide) 4. Rotate bumper 90 degrees once a day
55
What are the 4 feeding schedules?
1. Bolus feeding 2. Intermittent feeding 3. Cyclic feeding 4. Continous feeding
56
Describe bolus feeding
liquid infusion less than 30 minutes of 250-400 mL per administration 4-6 times a day.
57
Disadvantage of bolus feeding
Causes abdominal distention, high risk for gastric reflux and aspiration
58
Describe intermittent feeding
Liquid infusion 4-6 times a day of 250-400 mL per administration for 30-60 mL
59
What is a key requirement of intermittent feeding?
Container and feeding tube needs to be flushed throughly after each feeding to reduce microorganism growth
60
How often are feeding tube sets replaced
Every 24 hours
61
Describe Cyclic feeding
infusion for 8-12 hours followed by 12-16 hour pause
62
When is cyclic feeding usually used and what time is it given?
To wean clients off of tube feeding and late evening and sleeping
63
Describe installation rate of continuous feeding
1.5 mL/minute
64
Continuous feeding is fed into where?
The small intestine
65
Benefit of continuos feeding
Reduces risk of gastric reflux since formula is fed directly into intestine
66
What are key aspects of the daily nursing assessment following tube insertion?
1. Weight 2. Condition of nasal oral mucosa 3. Fluid intake and output 4. Bowel sounds 5. Lung sounds 6. Vomiting naseua 7. Bowel patterns 8. Abdominal distention 9. Skin around ostomy
67
What is a mandatory requirement of the nurse to obtain once feeding schedule has started?
Gastric residual
68
Purpose of obtaining gastric residual
To determine wether fluid intake exceeds client's physiological capacity
69
What is the rule of thumb of obtaining gastric residual?
Should be no more than 100 ml or 20% of the last hours feeding volume
70
What action is performed if gastric residual is higher than normal?
STOP feeding, recheck residual every 30 minutes until normal volume
71
What is the best way to maintain tube patency?
Flush tube with 30-60 mL of water prior and after feeding (every 4 hours if on continuous feed)
72
What liquid can be used to flush a tube other than water?
Cranberry juice
73
What are two ways to clear tube obstruction and what is required from both of them?
1. Meat tenderizer 2. Pancreatic enzymes Both require medical order
74
How much water does an adult client require?
30 mL of water per kg of bodyweight
75
Steps to clearing obstructed tube
1. Choose 50 mL syringe 2. Wash hands 3. Don gloves 4. Aspirate as much as possible from tube 5. Instill 5 mL solution 6. Clamp tube and wait 15 minutes 7. Aspirate and flush with water
76
When, why and how long do we ambulate the patient on which side?
After assessing that the nasointestinal tube is in the stomach, to aid the weighted tip in traveling through the pyloric valve and for 1 hour on the right side
