21
Q

name some easy to swallow foods

Study These Flashcards
A

-cooked veggies
-ground meat
-creamed soup
-iced fruit

22
Q

name some different types of therapeutic diets and describe em a little

Study These Flashcards
A

-NPO (most restrictive, can vary)
-clear liqs (see through and liq at room temp)
-full liqs (anything liq at room temp)
-GI soft/low residue (gentle to digest)
-high fiber (whole grain foods)
-low sodium (<2g sodium per day)
-low cholesterol (low animal fat diet, lean meats)
-diabetic (ADA) (carb controlled/sugar controleld)
-regular (anything and everything)
-pureed (baby food like)
-mechaincal soft (easy to chew)
-enteral feeding (tube feed, can be used to supplement PO intake)

23
Q

describe enteral feeding

Study These Flashcards
A

-used when PO consumption can not occur or is not enough
-nasogastric
-gastrostomy
-jejunostomy

24
Q

describe parenteral nutrition

Study These Flashcards
A

-administered through IV
-total parenteral nutrition (TPN)

25
# purpose of enteral tubes feeding
administration of nutritional formula via tube in the digestive system
26
# purpose of enteral tubes lavage
-remove of stomach content -accidental poisoning, overdose -may instill NS to "wash" the stomach
27
# purpose of enteral tubes decompression
-connected to low intermittent wall suction -treats: bowel obstructions, paralytic ileus,and prevents distention
28
describe NG tube - levin/salem sump
-clear, larger, frim plastic tube -manipulate to soften tubing -check placement (gastric pH, tube length, visualization of contents) -confrom placement only with Xray -14-18 French is normal (smaller # = thinner)
29
what supplies will you need for NG tube placement
-NG tube -emesis basin -tissues -water based lube -cup w water and straw -tube securement shit -skin protectant -syringe -safety pin
30
describe the process of NG tube placement
-gather supplies, ID pt, provide instructions, wash hands, provide privacy -place pt in fowlers position -determine length for NG tube -mark tubing or note striped marking on tube -glove, lubricate tube (3-4 inches) -first have pt tilt head back to pick nostril -have pt tilt head forward -instruct pt procedure will be uncomfy -advance tube while asking patient to swallow -secure to nose -follow hospital policy for placement verification
31
describe NG tube - dobbhoff/corpak
-smaller tube diameter -softer plastic (soak in an ice bath to firm up plastic for easier insertion) -used only for feeding (can not aspirate or tube will collapse) -confirm placement only with Xray -can be used up to six months
32
describe gastrostomy
-G tube, PEG tube -inserted through the abdominal wall directly into the stomach -surgical procedure (difference from PEG tube how they are inserted) -incision in the abdomen -sutured in place -for long term use, can be permanently -norml to have leakage while healing
33
describe jejunostomy
-J tube -tube inserted through the abdominal wall directly into the jejunum -regurgitation and aspiration is prevented (stomach is bypassed) -emesis may still occur (only bile and stomach contents not food)
34
what are some nursing responsibilities r.t enteral tubes
-monitor I and O -provide nasal and oral care -always assess tube placement before use -maintain patency (irrigate with 30-60ml of warm water several times a day) -if ordered, maintain suction
35
how do you determine the length needed for NG tube placement
measure from -tip of nose to -helix or tip of ear to -the xiphoid process
36
when should you shut of suction to eneteral tubes
-for abdominal assessment -30min after administering meds
37
describe tube feeding administration
-fowlers position (verify placement and check residual) -clean technique -forula should be kept at room temo (hang only enough to infuse in 8 or less hours) -formula may be diluted -label administration tubing/syringe with date and time
38
what us a person at high risk for when getting tube feeds
aspiration
39
how can tube feeds be administered
bolus or continuous
40
describe checking gastric residual volume (GRV)
-aspirate gastric content via the tube (measure the amount aspirated) -return aspirated contents to the stomach -check MD order for acceptable residual amount prior to feeding (usually notify providor if residual is greater than 200ml (pt at risk for aspiration and absorption deficiency)
41
complications of tube feeding
-diarrhea (most common and more frequent with continuous feedings) -dry mouth -aspiration -displacement of tube -mucosal/skin irritaion -electrolytes imbalance -elevated blood glucose levels -gastric distention -occlusion
42
describe medication administration with tube feeding
-liquid form of med is preferred -many tablets can be crushed and dissolved in water -do not crush eneteric coated or time released capsules -many capsules can be opened and dissolved in water, check drug guide
43
describe medication administration enteral route
-use a bulb/piston 60ml syringe or an oral/enteral syringe (gather 60ml warm water. 30ml to flush before and 30ml for after) -follow three checks, triple checks and six rights. use 2 patients identifiers -crush and dilute medications in warm water -perform necessary assessments -elevate HOB to 30-45 degrees. place chux ot towel under tube -put on gloves and insert syringe into tube -if pt has been receiving tube feedings, check institutional policy regarding residual aspirate -you can test the stomach contents for acidity by using pH paper -close off NG tube by bending it back. if using PEG, use clamp to close off tube -holding the tube and syringe in nondominant hand, unbend NGT or release clamp and flush the tube -pour med into syringe. if the pt shows discomfort, stop procedure and wait until patient is relaxed -after all the med flows in, flush with 30ml of water -shut the tube bending it back or clamping, remove syringe -either clamp the tube or restart feedings -if NGT is being used for decompression, wait at least 20-30mins before resuming suction -leave HOB elevated at least 30-60mins
44
describe TPN
-aka hyperalimentation -infused into central line -hypertonic solution
45
who is TPN used for
those with... -difficulty absorbing nutrients -persistent nausea and vomiting -need for complete bowel rest
46
what are some complications associated with TPN
infection, fluid overload, metabolic imbalances
47
nursing responsibilities TPN
-I&O -daily weights -assess and manage central line -monitor lab values
48
what lab values are important to monitor with TPN
-glucose (may experience increased glucose while feeding and decreased afterwards) -urine ketones and specific gravity -BUN, liver function -electrolytes
