CHAPTER 9/10: ENTERAL NUTRITION AND TPN Flashcards

1
Q

Who gets enteral nutrition?

A

patients who are not able to consume adequate nutrients orally, but have at least a partially functioning digestive tract (stomach or small intestine)

** patient have condition that increases risk for malnutrition, neuromuscular impairment impacting chewing and swallowing, no gag reflex, infant who can’t swallow or suck **

Q

What are the 2 types of enteral feeding options?

A

o NG Tube (Nasogastric): goes from nose to stomach
▪ Short-term use (3-4 wks)
▪ Duodenal (to duodenum) or jejunal (to jejunum) typically for people at r/f aspiration d/t gastroparesis (delayed gastric emptying)

o Gastrostomy tube: tube inserted directly into the stomach or intestines
▪ Long-term use
▪ PEG tube or G tube
> G-tube: skin level, comfortable, immersible in water; harder to check residual
▪ Jejunostomy –> J tube

Q

What are the 2 formulas for enteral feedings?

A

o Standard/polymeric: whole proteins, require a fully functioning GI tract
* Standard formula: low residue and high fiber  better for minimizing gas (ex. bowel rest, postop bowel surgery) or normalizing diarrhea or constipation*

o Hydrolyzed/elemental: partially digested (broken down) protein/nutrients, can be used if a patient has a partially impaired GI tract

Q

What are the main nursing care for enteral feedings?

A
  • When you first place the tube, you NEED to verify tube placement using an XRAY
  • Measure gastric residual every 4-6 hours**
  • Flush the feeding tubes with 30 mL of water every 4 hours***
  • Solution should be at room temperature*****
  • Flush the tubing with 15-30 mL of water before, after, and in-between medications****
  • Slowly increase the volume or rate to the desired level***

Q

What are the nursing care for enteral feedings?

A
  • When you first place the tube, you NEED to verify tube placement using an XRAY
  • A CLIENT CAN DEVELOP DIARRHEA if the FORMULA infused is TOO COLD.. so warm it to room temp before administration
  • Measure the tube each shift and before each feeding
  • Verify the presence of bowel sounds before each feeding
  • Discard bags and tubing associated with the feeding every 24 hours
  • Measure gastric residual every 4-6 hours**
  • Return the residual to the stomach!!
  • Hold feeding if the amount of the residual exceeds whatever the hospital policy is (usually about 500 mL or >25% of feeding vol in kids)
  • Flush the feeding tubes with 30 mL (or 20-50 min) of water every 4 hours***
  • Solution should be at room temperature*****
  • Elevate the head of the bed at least 30 degrees during feeding and for 30-60 minutes after the feeding to help prevent aspiration
  • Flush the tubing with 15-30 mL of water before, after, and in-between medications****
  • Cover and label any unused formula with patient information and refrigerate it for up to 24 hours (after 24 you get rid of it)
  • Fill feeding bag with only 4 hours’ worth of formula to prevent bacterial contamination
  • Slowly increase the volume or rate to the desired level***
    o When someone first starts you start the rate very low (5-10 mL per hour) and then slowly increase it to desired rate
    o When you are weaning them off you’re going to do so slowly versus abruptly discontinuing it
    ▪ You will have weaned them as their oral consumption increases

Q

How should medications be given via enteral feeding?

A
  • Stop feeding prior
  • Flush w/ 15-30 mL water before and after med admin, and between meds if multiple are being given
  • Use liquid meds if possible; dissolve tablets in water not in formula
  • For kids, use 1.5x amount predetermined to flush an unused feeding tube of same size

Q

How should you wean a patient off of an enteral feeding?

A
  • Start weaning if can eat 2/3 protein and calories orally for 3-5 days
  • Stop EN 1hr before meal
  • Slowly increase PO meals to 6 small meals/day
  • When PO intake = 500-750 cal/day, switch to cyclic feeds at night

Q

What complications can result from enteral nutrition?

A
  • GI
    > Slow infusion rate
    > Administer at room temp
  • MECHANICAL
    > Unclog tubing w/ 30-50 mL warm water in > 60 mL syringe
  • FOOD POISONING
    > Wash hands
    > Formula cans: clean tops, cover and label w/ name, room, date and time opened
    > Use closed feeding systems
    > Refrigerate unused portions for max 24hr
    > Replace feeding bag, tubing, and any mixing equipment q24hr
    > Fill generic bags w/ 4hr worth of formula

Q

What is parenteral nutrition and who needs it?

A

Nutrient formula put directly into vascular system AKA a vein (GI tract not working)

Patients who have:

  • GI disorders
  • Cancer
  • Critical illness
  • Trauma
  • Burns

Q

What is TPN?

A
  • ** more common ***
  • long-term therapy (over 7 days) w/ hypertonic solution (>10% but <70%) dextrose - r/f hyperglycemia
  • must be given in central vein (PICC line or central line)
17
Q

What is PPN?

A

short-term (7-10 days; 14 day max); nutritionally incomplete, isotonic solution (must contain <10% dextrose) that is given via a peripheral vein

18
Q

What are contradictions to IV lipids?

A

** can be admin. via piggy back **
patients who have allergies (soybean oil, safflower/sunflower oil or eggs), severe hyperlipidemia or severe hepatic disease

19
Q

What are some PPN nursing interventions?

A
  • Use micron filter on IV tubing for PN (not for lipid emulsion)
  • If the next bag isn’t available, give IV dextrose 10%-20% (D10W or D20W); you NEVER stop the TPN abruptly**
  • Don’t increase rate of PN to ”catch up” if missed
  • If solution is “cracking” (oily layer on top of solution), do not use
  • Allow to come to room temp for 1hr before admin
  • Verify the parental nutrition bag with a second RN, check the prescription and contents of the bag before administering it
  • Sterile technique to change central line dressing and tubing
  • Change bag and IV tubing q24h
  • Hang lipid emulsion <12h
  • Stop lipid infusion 12h before drawing TRG
  • Notify if gain >1kg/day
  • Cannot be given if patient has a egg allergy
  • Monitor I & O’s daily weight, electrolyte levels, blood glucose level
20
Q

What complications can unfold from PPN?

A
  • Infection
  • Metabolic complications (FVO, hyperglycemia, dehydration)
  • Mechanical complications d/t central line
  • Refeeding syndrome: rapid change from starvation-induced catabolism to anabolism after feeding started
    > S/Sx: F&E imbalances (K, Mg, P), shallow
    breathing, confusion, seizures, weakness,
    dysrhythmias, fluid retention, acidosis
21
Q

What medications can you add to the parenteral nutrition bag?

A
  • Insulin
    o Giving them a lot of dextrose through the bag, this carries a risk of hyperglycemia
  • Heparin
    o Helps to prevent clot formation at the IV catheter tip
22
Q

What should you do if you need to give a patient with a TPN medications?

A

you never ever want to administer it through the same line as their TPN, they need a separate line

23
Q

When can parenteral nutrition be discontinued?

A

when oral intake is at least 60% of the daily caloric requirements for the patient

24
Q

Why should parental nutrition be stopped gradually?

A

because that can tank their blood sugar levels
