21
Q

GI diagnostic evaluation

A

  • Lower GI Tract study
  • CT, MRI, PET scans
  • Endoscopic Evaluation
22
Q

Which diagnostic evaluation is low coat and immediate results?

A

Abdominal ultrasound

23
Q

Pre-op abdominal ultrasound guidelines

A

Fast 8-12 hours pre-procedure
Gallbladder studies: fat-free meal night before

24
Q

In which diagnostics is a contrast used?

A

Upper GI
Lower GI

25
In upper GI study, what contrast is used?
Barium or hypaque
26
What does an upper GI study detect?
Detection of anatomic or functional disorders of upper GI organs
27
Pre-op guidelines for upper GI study
- Clear-liquid diet & bowel prep - NPO midnight before exam, hold am PO meds
28
Which diagnostic used a barium instillation (barium enema)?
Lower GI Tract study
29
Contraindications for lower GI study (3)
Active inflammatory disease of colon - Obstruction or suspected perforation - Active GIB (may preclude enemas or laxative use)
30
Pre-op guidelines for lower GI study
- Low residue diet 1-2 days - Clear liquids - Laxative the evening before - NPO after midnight - Cleansing enema until clear am of test
31
Which diagnostic can be done with or without contrast?
CT, MRI, or PET scans
32
What do we evaluate before and after CT, MRI, or PET scans?
BUN
33
Do we identify allergies before diagnostics?
Yes
34
Endoscopic Evaluation
Upper GI (EGD) Lower GI (Colonoscopy)
35
After using a contrast during a diagnostic, what do we do?
Administer Mucamyst before or after Administer sodium bicarb Increase IV fluids to flush contact out
36
Guidelines for Upper GI Endoscopy
- NPO 8 hours before test - If emergency, suction stomach - IV sedation for comfort - Throat sprayed with local anesthetic (remove dentures or dental appliances)
37
Guidelines for post-procedure Upper GI Endoscopy
- Frequent VS, oxygen saturation, pain - Gag-reflex return - Flatus - I's&O's
38
Diagnostic Tests
- Upper GI Endoscopy - Lower GI Endoscopy
39
Guidelines for Lower GI Endoscopy (Colonoscopy)
- Bowel preparation (laxatives, enemas) - Clear-liquid diet day before procedure - Fast morning of test - Explain procedure to pt
40
Guidelines for post-procedure Lower GI Endoscopy
- VS, oxygen saturation, pain - Pt to report any blood in his stool - Flatus - Can eat in 1 hour
41
For patients who are in severe danger, like puking up blood, what do we do if we need immediate Upper Gi Endoscopy?
NG tube
42
Nursing roles for GI: Assessment
- Monitor labs (S/S infection, send specimens immediately to lab) - Abdomen (rigid/soft, bowel sounds) - Pain - VS - Fluid volume status (I/O, daily weight), mucous membranes, JVD) - Bleeding - Patient/family education (procedure, pre/post-op expectations)
43
If we suspect bleeding of GI during assessment, what else will we do?
We will also look in the stool or vomit, but also monitor CBC, PT, INR, platelets (clotting factors)
44
Drug therapy treatment for GI disorders (8)
- Antacids - Digestants - Proton pump inhibitors - Anticholinergics - Antidiarrheal agents - Laxatives - Emetics - Antiemetics
44
Treatment for GI disorders
- Drug therapy - Surgery
45
Surgery treatment for GI disorders (8)
- Esophageal surgery - Gastric surgery - Bowel surgery with ostomy - Bowel resection and anastomosis - Appendectomy - Gallbladder surgery - Liver resection or repair - Trans jugular intrahepatic portosystemic shunt insertion (TIPS)
46
What is anastomosis?
Removing a portion of the bowel and sewing it back together
47
Nursing DX for patients with GI disorders (7)
- Pain - Anxiety - Fear - Knowledge - Skin integrity (severe diarrhea) - Ineffective tissue perfusion - Fluid/Electrolyte disorders
