Q

GI assessment: auscultation

A

Normal: low to high pitched gurgling, 5 to 30/min

- Med adherence: PPI, H2 receptor antag, antacids, avoid OTC meds for dyspepsia if taking prescription meds - Avoid eating w/in 2 hrs of bedtime - Avoid PUD risk factors: NSAID, alc, aspirin, spicy food
43
Types of Hernias
- Inguinal: intraabd fat/SI protrudes around inguinal canal - Indirect: congenital, inguinal doesn't close after birth - Direct: connective tiss degen weakens muscles - Femoral: preset below inguinal ligament 40% present as incarcerated - Umbilical: omentum and fat incarcerates - Ventral (or incisional): prev abd surgeries, often midline incision in upper area
44
Incarcerated/Strangulated hernia
- Surgery is more extensive - May result in temp colostomy
45
Reducible vs. Irreducible/Incarcerated hernia
- Reducible: contents easily reenter the abd by lying down or gentle pressure - Incarcerated: contents can't be placed back into abd cavity (medical emergency)
46
Hernia nursing assessment
- VS (temp: infection) - Pain - I&O - Surgical site (well approximated)
47
Hernia
Protrusion of abd contents thru area of weakened muscle in abd wall

61
Characteristics of ulcerative colitis
- Colon, rectum. Begins in rectum and advances in continuous process to cecum - Mucosa and submucosa of colon - Freq watery stools w blood and mucuous - 10-20 liquid and bloody stools - Tenesmus: COMMON - Hemorrhage, nutritional deficiencies - Cure w colectomy
62
IBD Psychosocial issues
- Body image disturbance - Embarrassment - Depression and anxiety - Loss of independence
63
Crohn's & surgery
Removal of diseased bowel is not curative, disease often returns in another area of bowel
64
What leads to surgery for UC?
Ineffective medical management or complications from medical management
65
Surgical management of IBD
- Total colectomy w ileal pouch anal anastomosis (IPAA): entire colon & rectum removed, pouch created to collect waste, person can defecate normally - Proctocolectomy w permanent ileostomy
66
IBD nursing assess
- History: freq diarrhea leading to extreme fluid loss and electrolyte abnormalities (hypokalemia) - VS: tachy, hypotension, low grade fever - Weight: decreased intake d/t fear of worsening sympts & malabsorp - I&O - Freq and characteristics of stool - Psychosocial support - Nutritional intake
67
IBD nursing interventions
- Administer IV fluids & supplemental potassium as ordered - EKG monitoring if significant hypokalemia - Administer blood products & abx as ordered - Small frequent meals (decrease intestinal motility) - Rest periods (decrease intestinal motility) - Pain management: positioning, medications, monitoring for side effects such as constipation - Skin care: freq diarrhea, presence of ostomy
