Question | Answer |
Where do you place a GI tube | past pyloric sphincter into duodenum/jejunum |
What r fxs of GI intubation? | decompress stomach of gas/fluid, lavage and remove toxins, diagnose disorders, adm meds/feedings, compress bleeding site, aspirate gastric contents for analysis |
What are two common gastric tubes | Levin: single lumen, short for suction, not feeding. Use low intermittent suction. Gastric Sump: double lumen, blue vent(keep above pt waist) |
What are enteric tubes | provide nutrients |
what is key nsg mgmt for tube placement? | check placement with xray, air(unreliable) bubble ea time meds/liquids adm, once a shift for continuous feedings |
How else should nurse measure placement of tube | Measure exposed portion of tube and document |
what is diff in gastric aspirate and intestinal? | gastric: cloudy, green, tan, off-white, or brown. intestinal: clear, yellow to bile |
What is pH of gastric vs pH of intestinal | gasstric: 1-5 intestinal: 6 and higher respiratory: 7 or higher |
How to measure NG tube for placement | 1. measure from nostril to tip of lower earlobe 2. Then measure from earlobe to tip of xiphoid process. 3. Add 6-10cm and mark |
How often should you irrigate an NG tube? How often should you check for discharge of NG tube? | Irrigate q4-6h discharge q4-8h |
Before removing NG tube what is good idea to do before? | 1.Clamp it for trial period to test for nausea/vomiting. 2. Flush with 10ml water/ns so tube is free of gastric lining |
What is normal osmolality of body? How to avoid dumping syndrome? | 300mOsm/kg slow formula, room temp, semi-fowlers for 1h, minimal water to flush b4 and after feeding |
what is dumping syndrome? | solutions high in osmolality pulls water into stomach/sm int from organs and vascular. s/s: nausea/dehydration/hypotension/tachycardia |
What are main nsg goals for enteral & parenteral feedings | Achieve positive nitrogen balance, wt maintenence or gain w/o discomfort or diarrhea |
what is positive nitrogen balance | protein synthesis is greater than protein breakdown resulting in tissue growth |
How often are residual gastric volumes measured and what is acceptable amount? | intermittent feedings: b4 ea feeding continuous: q4-8h Residual vol >200 signal alarm for aspiration *Always return residual back to pt |
Patients at risk for delayed gastric emptying include | gastroparesis, poorly controlled diabetes mellitus, gastric outlet obstruction, ileus, recent surgery, trauma, or sepsis and those using a large amount of narcotic pain medication. |
B4 adm of meds/feeding, after checking residuals, q4-6h of continuous feed, interrupted tube feeding, unused tube feeding...what should nurse always do? | flush wtih 30-50ml water or NS and record as intake |
how often should tubing be changed with tube feedings? How long can bag of formula hang | q24-72h formula good for 4h |
what is priority in assessing pt with tube feeding? | 1.check placement(below pylorus is best), elevate HOB 2.check residual |
What are nsg interventions for diarrhea and enteral therapy | 1.check rate of flow and temp of formula(hyperosmolar feeding, cold) 2.avoid pro motility meds(reglan) 3. asses F&E levels |
nsg interventions for nausea/vomiting for enteral therapy | 1.review meds 2.check residuals (inadequate gastric emptying, ileus, gastric block, infection) |
nsg interventions for gas/bloating for enteral therapy | keep tubing free from air |
nsg intervention for constipation for enteral therapy | flushes to hydrate, cathartics(inadequate fluid/fiber, opioid use) |
what can cause aspiration pneumonia? | improper tube placement, vomiting w/ aspiration of tube feeding, supine Intv: assess resp, check placement |
Causes of tube displacement | coghing/vomiting, unsecured tube, tracheal suctioning, airway intubation Intv: stop feeding, call Dr |
Causes of tube obstruction | inadequate flushing/formula rate Intv: declog, get liquid meds, flush |
causes of hyperglycemia, dehydration, azotemia(excess urea in blood) | glucose intolerance, hyperosmolar feedings, low fluid intake Intv: assess dehydration s/s, change feedings or formula, hydrate |
How should enteric coated, timed released tablets be adm wtih tube feedings? | Never crush! Call pharmacy for alternate form |
what is a gastrostomy? | PEG tubes opening in stomach to insert feeding tube or decompression. Usually used if enteral nutrition needed for longer than 4 weeks, preferred for coma pt(regurgitation less) |
What is usual first feeding of peg/jejunostomy tube | tap water, NS, 10% dextrose at slow rate 10-20ml/hr, or small bolus 30-60ml |
what are nsg goals with gastrostomy? what are intv for ea? | pain, prevent infection, GI bleeding, skin integrity, body image Intv: gauze b/n skin & tube, pH check of contents, check amt if suctioned: low(clamp off), high(check F&E) |
What is parenteral nutrition and when is it indicated to use? | nutrition through IV route b/c pt not ingest oral food in 7 days |
How much PN is adm usually over 24h? What is sig about IVFE(intravenous fat emulsions)? | 1-3L; inspect for separation and don't use if oily appearance IVFE: can be along with PN thru Y connector. Don't filter |
What kind of pump is always used for PN | infusion pumps |
PPN(peripheral parenteral nutrition) can supplement oral nutrition thru peripheral vein...what precautions are needed to protect the vein? | Not adm >10% dextrose solutions cause of phlebitis and lipids are adm with to protect them. |
what are 4 types of CVADs(central venous access devices) to adm CPN? Where are they inserted? | Nontunneled(percutaneous) central catheters: subclavian vv Peripherally catheters(PICC): basilic/cephalic vv Tunneled catheters: long term Implanted ports: Huber needle Inserted in subclavian veins usually |
what is key for nsg intv when doing dressing changes and working with CVADs? | sterile technique incl mask |
what is important nsg assessment with PN adm? | Assess I/O q8h to assess fluid imbalance. If solution runs out infuse 10% dextrose & water til next PN |
What is cause and nsg intv, prevention for pneumothorax complicationg of PN? | cause: improper catheter placement, punture of pleura Intv: Folwer's, monitor VS, prepare for chest tube Prvt: Pt still in Trend @ insert |
What is cause and nsg intv, prevent for embolism complication of PN? | Cause: tubing disconnect, cap missing from port, blocked vascular segment intv: replace tube/cap/call Dr, turn pt to left side and head lowered prvt: examine tubing connection sites |
What is cause and nsg intv, prevent for clotted catheter line complication of PN? | cause: inadequte hep flush, disruption of infusion intv: flush per Dr order prvt: moniter infusion rate hourly, inspect line integrity |
What is cause and nsg intv, prevent for sepsis complication of PN? | cause: separation of dsg, bad solution, inf at insertion site intv: change dsg quickly, call Dr/monitor VS prvt: maintain sterile tech |
What is cause and nsg intv, prevent for Hyperglycemia complication of PN? | cause: glucose intolerance intv: call Dr for insulin prvt: monitor glucose/urine output/assess for stupor/confusion/lethargy |
What is cause and nsg intv, prevent for fluid overload complication of PN? | cause: infusion too rapid intv: decr rate, monitor VS, call Dr., sit upright if resp distress or give O2 as needed prvt: verify correct infusion rate ordered |
What is cause and nsg intv, prevent for rebound hypoglycemia complication of PN? | casue: feeding stopped too abruptly intv: assess for s/s(weakness/tremors/diaphoresis/HA/hunger/apprehension prvt: gradually wean pt |
