these are signs of perforation post EGD, which is a esophogus/stomach scope

25
Liver, gallbladder, pancreas are
Accessory organs of digestion produce or store digestive secretion
26
Liver
Hepatic portal circulation
27
Páncreas
•amylase—starch>maltose •lipase—emulsified fats>fatty acids/monoglycerides •trypsin—polypeptides to peptides •bicarbonate juices
28
S/S of GI Alterations
•abdominal pain •nausea/vomiting •diarrhea •constipation
29
Abdominal pain (etiology & assessment)
•common •reasons: obstruction, peritonitis, altered motility, stress, lesions etc •assess: onset, character, location, severity, interventions etc
30
Náusea & vomiting & prevention
•náusea—gotta vomit…drooling, weakness, hyper/hypotension, sweats •vomit—emesis, stimulated by CTZ, rids body of harmful stuff •hematemesis- bloody vomit, breath may smelly poopy •prevent aspiration, monitor /correct fluid balances
31
Diarrhea
•reasons: meds, anxiety, infection, diet, laxative, malnutrition •assess duration, amount, character, etc, fever present(?) •maintain skin hygiene, anti-poop meds, fluid balance
32
Constipation (RAPDISS)
•Reason: meds, need fiber, need fluids, gastric stasis, immobility etc •assess: bowel patterns, diet, lax use…treat with diet change/meds •prevention: exercise, high fiber diet, fluids •S/S—bloated abd., indigestion, rectal pressure, incomplete poop, hard poop, rumbling •issues: impaction, ulcer, heart rupture from straining, megacolon •dx: history & physical •solutions: prevention, exercise, softeners
33
Physical assessment
•Ht./Wt. •BMI (18.5-24.9) •mouth (loose teeth) •abdomen—look for jaundice etc, listen, feel (girth), tap (Dr.),
34
Diagnostic Testing
CBC, electrolytes, CEA (cancer), billirubin, liver/pancreatic enzymes
35
Stool Testing color
•tarry-upper GI bleed •frank–near rectum •occult —least invasive blood in poo test
36
Occult &Parasite Exam
•Occult–3 tests, meat free 72 hours pre exam…bleeding gums, food, meds can cause false + •ova/parasite–3 tests, finds pathogens/bacteria, no urine allowed, specimen fresh & warm
37
Fecal fat/Stool Cultures
•fecal fat–24 hr collection, test for malabsorption, crohn’s, pancreas issue •stool culture—finds pathogens
38
Barium Swallow
•aka upper GI series …view of esophagus, stomach, duo/jejunum with barium •NPO 6-8 hrs pre midnight, laxative post test, poop watched for barium, monitor for constipation, drink 12 8 oz water post study •test takes hours
39
Barium Enema
•aka low GI series … looks at where/how full/ is colon •unclear bowels=cancel study •contraindicated with colon disease/perforation/obstruction •finds polyps, hernias, motility, tumors, stenosis, colitis, diverticula •same stool watch as UGI..PT should report bloating /constipation/bleeding •test takes 15 minutes
40
Endoscopy (pathophysiology)
•invasive, requires consent, direct visual/ ability to biopsy •**cauterize bleeding, remove polyps**
41
Esophagogastroduodenoscopy
•see esophagus, stomach, duodenum •finds cancer, bleeding, infection, biopsy/cyto specimens can be taken •**watch V.S., prevent aspiration** •**RUQ pain, fever, chills—infection**
42
Proctosigmoidoscopy
•lower GI scope…looks at colon, rectum , anus •finds ulcers, punctures, hemorrhoids, polyps, can get specimens •laxative pre, enema post
43
Colonoscopy (Pathophysiology)
•Can see the Lg intestine •watch for hemorrhaging, severe pain •blood in poop normal if stool specimen taken
44
Gastric analysis
•stomach secretion measurement •finds duodenal ulcer, gastric carcinoma, pyloric or duodenal obstruction, pernicious anemia •2 types of GA: Basal cell, gastric acid stimulation
45
Basal cell secretion test
•NPO post-midnight pre-test •stomach contents collected 4x/hr •GI acid tested for amount/acid •too much hydrochloric acid=maybe peptic ulcer, too little=cancer or pernicious anemia
46
Gastric acid test
Measures amt of gastric acid for HR after SQ injection of a histamine
47
A PT with DVT post op is started in IV heparin. Which lab test will the nurse monitor? 1. Prothrombin time 2. International normalized ratio 3. Partial thromboplastin time
3
48
Percutaneous Liver Biopsy
* identifies cancer, cirrhosis, hepatitis * small sample from liver extracted by needle * risk for bleeding * CBC/ coagulation study pre-biopsy * NPO 6-8 pre-biopsy * AVOID COUGHING/STRAINING POST-BIOPSY
49
NG vs EG, G tube, and J tube
Ng is shorter term, the rest are longer-term use
50
Why would PT need a GI tube
1. remove gas/fluid in stomach 2. diagnose GI motility/sample for testing 3. relieve/treat obstruction or bleeding 4. nutrition, hydration, medication 5. promote post-op healing 6. remove toxic substances
51
if you pull back 100 mLs after a feeding, what should you do next
PT isnt getting full feed, STOP THE FEED, call dr
52
Enteral nutrition
* supplies PT with nutrition * delivered into jejunum/duodenum * free water needs can be calculated by a dietician
53
Gastro decompression
NG tube usually used, suction applied
54
parenteral nutrition/periphreal para.
* feed goes thru IV * due to high dextrose lvl, accuchecks should be taken * imporves nutrition, promotes healing, wt. gain * PPN-used <10 days
55
Gastrointestinal Intubation
•tube for therapy/diagnostics •**gas & fluid removal** •**diagnoses GI motility & gastric secretion analysis** •relieves/treats obstructions or bleeding in tract •**provides nutrition, hydration, medication** •remove toxins (lavage)
56
salem sump
* most common * vents, prevents excess suction * do NOT plug off air vent * used for decompression, lavages •**weighted, flexible feeding tube with stylets**
57
Nasoenteric
* PT repositioned side to side for passage * used to decompress sm. bowel in Un-operable PTs
58
nursing management for GI tube PT
* nare care, check mouth (lose teeth), elevate HOB, educated PT pre/post-op * fluid balance, peristalsis presence
59
possible complication of GI tube
PERFORATION
60
What should a PT with GERD avoid?
eating large meals, lying down after eating, caffeine
61
why are antidepressants given for IBS PTs?
for hypercontractions
62
Liver needle biopsy summary
Watch for bleeding, limit movement, apply pressure, **Pt should avoid coughing**
63
True or false : NG tubes are usually permanent or long term
False, it is short term and temporary
64
Percutaneous Liver Biopsy
•needle used to get specimen to identify cancer, cirrhosis, hepatitis •NPO 6-8 hours before test •**risk for bleeding**
65
Endoscopic Retrograde Cholangiopancreatography
•**ERCP allows visual of liver, gallbladder, & pancreas** •removes stone/tumor removal, bile duct stent placement can be used •**NPO 8 hrs pre-op** •**Monitor for hypotension, tachy, high HR, rapid RUQ pain, n/v—these are perforation/pancreatitis signs** •**call Dr**
