23
Q

describe enteral feeding

A

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

24
Q

describe parenteral nutrition

A

-administered through IV
-total parenteral nutrition (TPN)

25
Q

purpose of enteral tubes

feeding

A

administration of nutritional formula via tube in the digestive system

26
Q

purpose of enteral tubes

lavage

A

-remove of stomach content
-accidental poisoning, overdose
-may instill NS to “wash” the stomach

27
Q

purpose of enteral tubes

decompression

A

-connected to low intermittent wall suction
-treats: bowel obstructions, paralytic ileus,and prevents distention

28
Q

describe NG tube - levin/salem sump

A

-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
Q

what supplies will you need for NG tube placement

A

-NG tube
-emesis basin
-tissues
-water based lube
-cup w water and straw
-tube securement shit
-skin protectant
-syringe
-safety pin

30
Q

describe the process of NG tube placement

A

-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
Q

describe NG tube - dobbhoff/corpak

A

-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
Q

describe gastrostomy

A

-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
Q

describe jejunostomy

A

-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
Q

what are some nursing responsibilities r.t enteral tubes

A

-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
Q

how do you determine the length needed for NG tube placement

A

measure from
-tip of nose to
-helix or tip of ear to
-the xiphoid process

36
Q

when should you shut of suction to eneteral tubes

A

-for abdominal assessment
-30min after administering meds

37
Q

describe tube feeding administration

A

-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
Q

what us a person at high risk for when getting tube feeds

A

aspiration

39
Q

how can tube feeds be administered

A

bolus or continuous

40
Q

describe checking gastric residual volume (GRV)

A

-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
Q

complications of tube feeding

A

-diarrhea (most common and more frequent with continuous feedings)
-dry mouth
-aspiration
-displacement of tube
