36
crohns disease vs ulcerative colitis
crohns disease is patchy inflammation throughout small and large bowel; UC is continuous and uniform inflammation in the large bowel
37
crohsn disease assessment
fever; cram like colicky pain in RLQ after meals that does not relieve with BM; chronic diarrhea with mucus and pus; abdominal distention; tenderness; anorexia, N/V; dehydration; weight loss; anemia; malnutrition; electrolyte imbalance
38
UC assessment
anorexia causing weight loss malnutrition and dehydration; electrolyte imbalance; vitamin K deficiency; malaise; abdominal tenderness in LLQ with cramping; severe diarrhea with blood and mucus; anemia
39
diagnostics testing for UC
imagine- CT scan, MRI, abdominal x-ray, colonoscopy with biopsies, ultrasound; labs- CBC, WBC, ESR/CRP, low albumin, electrolyte imbalance
40
interventions for crohns/UC
NPO, fluids IV, lectrolytes, parenteral nutrition, restrict movement to reduce intestinal activity, monitor BS/tenderness/cramping, monitor stools, administration of meds- salicylate/corticosteroids/antibx/immunosuppressants/antidiarrheals, avoid gas forming foods/whole wheat grains/nuts/raw fruits/veg./alcohol/smoking
41
crohns disease and UC surgical interventions
restorative proctocolectomy with ileal pouch anal anastomosis: removal of entire colon and rectum but keeps anal sphincter; total proctocolectomy with permanent ileostomy: removes all the large intestine and small intestine through and opening
42
stoma care
want bright beefy red stoma; pale pink is sign of low Hgb; purplish/black is sign of compromised circulation
43
diverticulosis
outpouching herniation of the intestinal mucosa and/or all layers without inflammation; can occur in any part of intestine but mostly in sigmoid colon
44
diverticulitis
inflammation of 1 or more diverticula that occurs from penetration of fecal matter through thin-walled diverticula; result in local abscess formation and perforation; perforated diverticula can progress to intra-abdominal perforation with generalized peritonitis; usually left lower quadrant
45
diverticulosis/diverticulitis assessment
LLQ abdominal pain increasing with coughing, straining, and lifting; flatulence; cramp-like pain; abdominal distention and tenderness; palpable tender rectal mass may be present; blood in stools; elevated temp.; N/V
46
diverticulitis/diverticulosis inteventions
bed rest, NPO with clear liquids; introductiNon of fiber containing diet gradually once inflammation resolves; admin antibx/analgesics/anticholinergics; refrain from strenuous activities (lifiting coughing);
47
NG tubes
decompress stomach by removing fluids and gas; administration of meds to those unable to swallow; prove nutrition by acting as feeding tube; can be used to irrigate stomach and remove toxins; can feed as bolus (30-60 min q3-6 hours), continuous, or cyclical (8-16 hours overnight)
48
admin of tube feeds
high fowlers, assess bowel sounds and hold if absent; assess tube placement via aspirating and check pH; warm feed to room temp.; maintain upright position for 30 min following bolus feed; flush with 30-50mL after feeding and then clamp 30-60 min after; tubing changed q24 hours
49
parental nutrition
is used as a last resort for supplying nutrients; supplies nutrients via veins and can be partial or total; supplies fats carbs and proteins; prevent fat and muscle protein from being broken down; is a hypertonic saline d/t ihgh glucose and amino acids
50
indications for admin of parenteral nutrition
dysfunctional or non-functional GI tract that cannot process nutrients; not enough oral nutrition; multiple GI surgeries or trauma; intolerance to enteral feeding; used when need to heal bowel; no other nutritional alternatives available
51
PPN
admin though large distal vein either standard PIV or midline/PICC or subclavian or IJ/EJ
52
TPN
continuous administration over 24 hours or cyclical overnight through central vein/PICC; must infuse via pump; admin D10W when TPN runs dry and waiting for new bag; watch for sclerosis, phlebitis, swelling; moitor glucose
53
when discontinuing TPN
need evaluation by nutritionist; gradually decrease flow for 1-2 hours while increasing oral intake; change IV dressing after removal until healed; encourage PO nutrition; record IO, weight, lab results of electrolytes and glucose levels
54
Parenteral nutrition interventions
validated by 2 RNs to ensure proper prescribed components; IV meds and blood not given through PN lines; blood can be drawn from central line but need to be stopped; monitor PT and PTT if receiving anticoags; monitor BGL, monitor for refeeding syndrome (rapid drop in K, Mg, and Phosph.), monitor central line infection; monitor liver/kidney function; refrigerate PN and admin within 24 hours
55

58
physical findingsing of appendicitis
local tenderness at McBurneys point on pressure (RLG 1/3 way from anterior iliac spine to umbilicus), rebound tenderness, rovisings sign (LLQ palpation causes RLQ pain)
59

pancreatitis
self-digestion by pancreatic enzymes; gallstone obstruct flow of pancreatic juice activating the enzymes; enzyme act. leads to vasodilation, increased permeability, necrosis, erosion, hemorrhage
62
causes of pancreatitis
infections, mumps complications, trauma, peptic ulcers, vascular issues, HLD, hypercalcemia, alcohol, tobacco, hereditary
63
interstitial edematous pancreatitis
mild common form characterized by gland enlargement due to edema; minimal organ dysfunction that resolves in 6 months; risk of shock, fluid electrolyte imbalance, sepsis
64

severe rare form with tissue necrosis in or around pancreas; enzymes damage blood vessels leading to bleeding and thrombosis; necrosis may extend retroperitoneal; can cause organ failure
65
acute pancreatitis assessment
severe abdominal pain that radiates to back that is aggravated by meals and unrelieved by antacids; abdominal guarding; rigid abdomen if peritonitis, bruising in flank (turners sign) or umbilicus (Cullens sign); n/v, fever, jaundice; hypotension, tachycardia, cyanosis, cold skin, resp. distress, hypoxia, AKI, hypocalcemia, hyperglycemia, coag issues
