pancreatitis treatment

A

control pain
decrease gastric secretions (NPO, NGT to suction)
bedrest
*****want the stomach dry and empty if anything gets in the body will want to make enzymes thats what is causing the pain

pain meds:
PCA narcotics
fentanyl patches

anticholinergics to dry the stomach:
benztropine
diphenoxylate

GI protectants:
pantoprazole
famotidine
antacids

maintain fluid and electrolytes

maintain nutritional status

Q

cirrhosis diagnostics

A

low serum albumin
high ALT/AST
ultrasound
CT/MRI

liver biopsy--confirms diagnosis
pre-procedure:
clotting studies pre-procedure (PT, INR, aPTT)
VS pre-procedure
supine w/ R arm behind the head
exhale and hold breath to get diaphragm out of the way
post procedure:
lie on R side
VS (worried about hemorrhage)

***if unsure why they’re swelling, ask for albumin levels

Q

cirrhosis treatment

A
antacids
vitamins
diuretics
no more alcohol 
i and o
weights
rest
bleeding precautions (no IM injections, no NSAIDs)
abdominal girth (ascites)
paracentesis:
remove fluid from the peritoneal cavity (ascites)
have them void
positing sitting up
VS (shocky clients BP goes down and pulse up)

monitor jaundice (good skin care)

  • **avoid narcotics (liver cannot metabolize drugs)
  • **diet (low protein, low Na)

Q

hepatic coma patho

A

protein breaks down into ammonia
liver converts it to urea
urea is excreted through kidneys

when liver is impaired it cannot make the conversion, ammonia builds up in the blood and causes a decrease in LOC

Q

hepatic coma s/s

A
mental changes
motor issues
difficult to awaken
asterixis (liver flap-hand tremors)
handwriting changes
reflexes will decrease
EEG will be slow
fetor (breath smells like ammonia)

Q

hepatic coma treatment

A

lactulose (decrease serum ammonia)
enemas
decrease protein in diet
monitor serum ammonia

20
Q

bleed esophageal varices patho

A

high bp in the liver (portal hypertension) forces collateral circulation to form in the stomach, esophagus, & rectum
no problem until it ruptures

21
Q

bleeding esophageal varices treatment

A
replace blood
VS
monitor CVP
O2
Octreotide lowers BP in the liver
endoscopic sclerotherapy (banding)
esophageal variceal ligation (injects sclerosing agent into the varices)

balloon tamponade:
sengstaken-blakemore tube
used to stabilize severe hemorrhage
dont use more than 12 hours
used to hold pressure on bleeding varices
**if it gets caught, use scissors to cut the tube and pull out)

enemas to get rid of blood
lactulose (decreases ammonia)
saline lavage to get blood out of stomach

22
Q

peptic ulcer patho

A

common cause of GI bleeding
can be in esophagus, stomach, or duodenum
erosion is present

23
Q

peptic ulcer s/s

A

burning pain in mid-epigastric area/back

heartburn (dyspepsia)

24
Q

peptic ulcer diagnosis

A
gastroscopy (EGD):
NPO pre procedure
sedated
NPO until gag reflex returns
watch for perforation by watching for pain, bleeding, or if they are having issues swallowing
upper GI: 
looks at esophagus and stomach with dye
NPO past midnight
***no smoking, chewing gum, or mints (smoking increases stomach motility which will affect test and increases stomach secretions which will increase the chance of aspiration)
*** remove nicotine patches
25
peptic ulcer treatment
antacids (liquid to coat stomach) ****take when the stomach is empty and at bedtime. when the stomach is empty acid can get on the ulcer so take antacids to protect the ulcer PPI "prazole" H2 antagonist (famotidine) GI cocktail (donnatal, viscous llidocaine, mylanta II) antibiotics for H. pylori (clarithromycin, amoxicillin, tetracycline, metronidazole) Sucralfate forms a barrier over the wound so acid can't get on the ulcer
26
peptic ulcer teaching
``` decrease stress stop smoking eat what you can tolerate avoid temp extremes and spicy foods avoid caffeine ```
27
two types of peptic ulcers
``` gastric: malnourished pain half hour to one hour after meals food doesn't help vomiting helps vomits blood ``` ``` duodenal: appear well nourished night time pain pain 2-3hours after meals food helps blood in stools ```
28
histal hernia patho
hole in diaphragm is too large so the stomach moves up into the thoracic cavity cause: large abdomen (lose weight), congenital abnormalities, trauma, straining
29
histal hernia s/s
heartburn fullness after eating regurgitation dysphagia (difficulty swallowing)
30
histal hernia treatment
``` small frequent meals sit up 1 hour after eating elevate HOB surgery teach lifestyle changes healthy diet ```
31
dumping syndrome patho
stomach empties quick after eating | client experiences uncomfortable to severe SE secondary to gastric bypass, gastrectomy, or gallbladder disease
32
dumping syndrome s.s
``` fullness weakness palpitations cramping faintness diarrhea ```
33
dumping syndrome treatment
``` semi-recumbent with meals lie down after meals on left side no fluids with meals small frequent meals avoid high carbs and electrolytes 9empty fast) ``` ***recline and dine * **left side lying = leaves it in * ** right side lying = releases it
34
ulcerative colitis and crohns patho
UC: ulcerative inflammatory disease, large intestine Crohns: inflammation and erosion of the ileum (small intestine) but can be found in large intestine
35
ulcerative colitis and crohns s/s
``` diarrhea rectal bleeding vomiting weight loss cramping dehydration blood in stools anemia rebound tenderness (push in, let go, and it hurts) means peritoneal inflammation fever ```
36
UC and crohns diagnostics
ct scan mri ``` colonoscopy*** clear liquid diet 24 hours prior NPO 6-8hours prior avoid NSAIDs laxatives or enemas until clear polkyethylene glycol (better icy cold) sedated post: watch for perforation ***Assume the worst pain and discomfort ``` barium enema: BE or lower GI series done if colonoscopy is incomplete
37
UC and crohns treatment
diet: low residue to limit GI motility to help save fluid avoid cold foods and smoking meds: antibiotics steroids (decrease inflammation) biologics and immunodulators (infliximab, adalimumab) aminosalicylates (decrease inflammation)-- sulfasalazine, mesalamine surgery: UC total colectomy, an ileostomy is formed kock's ileostomy or an illeal pouch anal anastomosis (no external bag, attaches to the rectum) crohns: try not to do surgery remove only affected area may end up with an ileostomy (ostomy in ileum) or colostomy (ostomy in colon)
38
ileostomy post op care
liquid stool all the time avoid foods hard to digest Gatorade or electrolyte for summer risk for kidney stones (dehydrated)
39
colostomy care
water and nutrients are being absorbed and the stool is forming when waste moves through the colon ascending and transverse (semi liquid stool) descending or sigmoid (semi formed or formed) need irrigation to give them some control regularly irrigate after a meal same time everyday anytime you give an enema and they cramp, stop the fluid lower the bad and/or check the temp of the fluid
40
appendicitis patho
inflammed appendix ***worry about rupture (lay them on their R side if ruptured)
41
appendicitis s/s
generalized pain and localizes in the lower R quadrant (mcburneys point) rebound tenderness n/v anorexia
42
appendicitis diagnostics
high WBC ultrasound ct dont give enemas or laxatives (worried about rupture-- perforation)
43
appendicitis treatment
surgery | fowler's position post op
44
TPN/TNA nursing considerations
``` ***don't mix anything with it keep refrigerated warm for administration let it sit a few minutes prior to hanging central line needed filter needed nothing else should go through this line daily weights may need to take insulin blood glucose monitoring q 6hours check urine for ketones and glucose mixture adjusted daily r/t electrolytes can only be hung for 24 hours change tubing with each new bag needs to be on a pump emphasize hand washing ****infection is huge complication ```
45
assisting to insert a central line
have saline available for fluids (3 10ml) don't start fluids until positive confirmation by CXR trandelenburg to distend veins if air gets in: left side trandelenburg ***worry about air bubble when changing to avoid air bubble: clamp it off walsalva take a deep breath and hummmmm xray done to check for placement and make sure they do not have a pneumothorax position to take out central line: lie flat and apply pressure
