25
Continuous feeding for a portion of a 24 hour period (i.e. Overnight)
Cyclic feeding
26
Why do you never use the plunger when you're when feeding patient using a large syringe?
Because administering a feeding too fast can cause G.I. distress
27
pH of airway
6.0 or higher
28
can meds be given through NG tubes?
yes, but not during feedings
29
Research recommendations for tube feeding in pts with dementia
Research recommends tube feedings not be used for this population because they do not increase survival or decrease aspiration risk or prevent malnutrition
30
during insertion, if there are signs of resp distress, excessive gagging, coughing, cyanosis, inability to speak or hum, etc, you should...
discontinue procedure and remove tube because it may be in the airway
31
Type of enteral feeding utilizing a gradual introduction of food for maximum apportion.
Continuous feeding
32
When using a feeding pump how often should you check tube placement and measure residual?
q 4-6 hrs
33
when advancing the tube past the pharynx, you should temporarily stop advancing when the pt ___ to avoid the airway
breathes
34
If there is a long term feeding situation and a G tube or PEG tube can't be used because GI tract is not fully functioning, you would place a ____
J-tube | Jejunostomy
35
Measurement for NI tube placement
measure just like an NG tube (nostril to ear lobe to xiphoid process) and then add 8"-10"
36
If CO2 is present, NG tube is in the ____.
Airway
37
Can be used to place a tube in the stomach without the use of general anesthesia.
PEG | percutaneous, endoscopic gastrostomy
38
Parenteral nutrition
Nutrition via IV therapy
39
Since infants are obligate nose-breathers, you may use what kind of tube instead of an NG tube?
OG tube (orogastric tube) through the mouth
40
preferred type of meds to give through NG tube
liquid whenever possible
41
common complications of enteral feedings
``` clogged tube aspiration nasal erosion (with NG or NI tubes) diarrhea, nausea, vomiting, distention unplanned extubation stoma infection ```
42
Jejunum
The part of the small intestine between the duodenum and the ileum.
43
Before beginning feeding, you should always...
Verify tube placement with multiple techniques, aspirate all gastric contents to measure residual, push residual back through tube and flush with 30 mL of water
44
NG feeding contraindications
``` Dysfunctional gag reflex Aspiration risk GERD Nasal injuries Unable to sit with head elevated at meal time ```
45
to secure tube...
tape tube to nostril and cheek and then have pt turn head to opposite side from tube and secure tube to gown.
46
Pt position for NI tube insertion
Position pt on right side
47
Med that increases GI motility
Reglan (metoclopramide)
48
How long should patient remain sitting upright after tube feeding?
At least one hour
49
if you meet resistance while advancing the tube...
do not force the tube and rotate it back and forth while gently trying to advance it.
50
Research recommendations on what therapies to use with dementia pts instead of tube feeding
Increased feeding assistance | Changing food consistency
51
reusable feeding systems should be cleaned how often?
every 24 hours with soap and hot water
52
NG tube
Nasogastric tube
53
Preferred and most effective method of feeding pts?
Oral feeding
54
after checking residual, you should do what to prevent tube occlusion?
flush with water
55
Next best thing if oral feeding is not possible
Enteral nutrition/feeding
56
Best check for G tube or J tube placement
Measurement of excess tube length
57
Enteral feedings preferred for feedings into the intestine
Continuous feedings
58
Syndrome caused by introducing too much food into the intestine at once. Causes nausea, distention, diarrhea, cramping and lightheadedness.
Dumping syndrome
59
before opening a can of fluid you should always...
check the expiration date and disinfect the rim
60
pH of intestines
7.0 or higher
61
"Gold standard" of NG verification
X-Ray (radiograph)
62
when inserting an NG and the tube reaches the pharynx, you should have pt...
touch chin to chest and sip water through a straw or swallow if NPO
63
In what way does continuous feeding alter the pH of the stomach?
Nutritional formula acts as a buffer and can make GI readings higher on the pH scale (alkalodic)
64
When using a large syringe (open system) how can you control the speed of the flow?
Since there is no plunger and the system is open, use gravity to adjust the flow rate by raising or lowering the syringe
65
when NG or NI tube is in place, perform oral hygiene every...
2-4 hrs
66
During, and for one hour after feeding, pt should remain as upright as possible, at what minimum angle?
Pt should sit up to at least a 30-45 degree angle
67
How is an NI tube inserted?
It's usually placed in the stomach and allowed to advance via peristalsis through the pyloric sphincter into the intestines
68
other uses for NG tube besides feeding
``` decompression of stomach drain fluid remove poison or meds from stomach monitor GI bleeding prevent intestinal obstruction ```
69
An ____ in excess tube length could mean the tube is dislodged
Increase
70
Check residual...
before feedings and every four to six hours during continuous feedings
71
ways to confirm NG/NI tube placement
X-ray, visualize aspirate, test pH of aspirate, check for presence of CO2. Make sure pre-measured mark is at the nostril.
72
If inserting an NG tube and coughing and gagging persist you should...
stop advancing and check placement with a tongue blade and flashlight
73
Enteral nutrition
Putting nutrients directly into the stomach
74
when pt has an NG tube in place, perform oral hygiene how often?
q 2-4 hrs
