Final Exam 2016 Flashcards
S/s liver disease/failure (RUQ)
Jaundice, pruritis(itchy), spider angiomas, red palms, anorexia, N/V, DULL right up quad pain, clay colored stool, fector hepaticus (sweet musty breath), portal HTN (ascites/varices), dark brown frothy urine, decrease u/o, hepatic encephalopathy, asterixis (liver flap), anasarca (fluid in skin), pleural effusion, leukopenia (NOTHING FRESH), K loss, confusion, male breasts, woman face hair, amenorrhea
Prevent liver disease
Avoid raw shellfish, vent room, protect skin, limit meds, limit ETOH
Interventions
Lotion, high calorie high carbs LOW PROTEIN, I&O, fluids, neuro: alarms, freq checks, elevate edema, pericentesis for ascites, respiratory: fowlers, arms out, conserve energy, nothing fresh, electrolytes
High PT/INR means?
Coumadin or liver disease
Most specific serum test for liver used to monitor tx
ALT
Post liver biopsy
Bed rest 12 hrs, lay ON SITE (pressure)
Portal HTN
Comp liver disease Ascites Peripheral edema Splenomegaly Increase venous pressure in portal circulation Varices HTN
Ascites main s/s and intervention
Abd pain, impaired respiratory, low u/o, low K, bacterial peritonitis
NA restrict
Diuretics
Paracentesis
Varices
Comp portal HTN (liver disease)
Bleeding/shock for esophageal varices
Gastric
Internal hemorrhoids
Caput medusae (around umbilicus)
Esophageal varices bleed tx
Caused from portal HTN
contributor: STRAINING, alcohol, coarse food
Stabilize and stop bleed (fluids, blood)
Tx w/ either sclerotherapy (heat), band ligation, balloon tamponade
Endoscopy interventions
Return of gag reflex, LOC, bleeding
Balloon tamponade care
For bleeding esophageal varices Patency Position via X-ray Saline lovage/NG suction Semi fowlers NPO Scissors at bedside
Shunting
Used after bleeding varices episode
Shunts blood out of portal vein
TIPS (non surgical)
COMPLICATION = ammonia build up
Hepatic encephalopathy
Life threat complication liver disease
Ammonia (normal 15-40)
Neurotoxic
Hepatic encephalopathy interventions
Limit protein Mental change Asterixis- Liver flap Hyperreflexia Fector hepaticus (musty sweet breath)

Gradual improvement
Malaise, fatigue
REST
2-4 months
Hep nutrition
High cal/card low fat/protein
Sm freq meals
Hep A
Fecal/oral, dirty water, raw shellfish
“Newsmaker”
Acute only
Hep A diagnostics
Anti-HAV (antibody to hep A)
Anti-HAV IgM (immunoglobulin=acute hep)
Anti-HAV IgG= (G=gone, past infection, future immunity)
Tx hep A
Vaccine prophylaxis
Immunoglobulin within 2 weeks
Hep B
Blood, body fluids, sex, needles ,perinatal
Lives on dry surface 7days
Carrier/infectious lifetime
HIV test
Chronic hep b
HBsAg positive 2x
Seen in very young
Interferon and antivirala
Hep c
Silent killer
Asymptomatic for yrs
No vaccine
Always infectious perinatal, percutaneous, permucosal
Symptoms usually jaundice/bruising/fatigue
HIV
antibody test
Colorectal cancer
Change in bowel pattern
Polyps
All abnormal need removed
Adenomatous/neoplastic linked cancer
Risk cancer increase w polyp size increase
Gradual/insidious onset (0 symptoms until advanced)
Polyp risk
Genetics IBD Age > 50 Increased red meat diet Lynch syndrome (born with hundreds polyps)
S/S polyps/colorectal cancer
Insidious/gradual Non specific Problems w/ bleed, obstruction, perforation, fistula Recent weight loss Iron deficient anemia Rectal bleed Abd tender Bowel change Hepatomegaly/ascites
Descending colon tumor s/s
Bleed and diarrhea
Ascending colon tumor
Detected later, presents as bowel obstruction
Cancer detect
Sigmoidoscopy Q5 years Or Colonoscopy Q10 yrs Age 50+ Yearly feckless occult blood tests
Colorectal cancer geriatrics
Fatigue
Iron deficient
Minor bowel change/bleed
Tenesmus (feeling to have to poop)
colorectal cancer tx
Stage 1 hemicolectomy
Stage 2 resection w/ or w/o chemo
Stage 3 surgery and chemo
Stage 4 palliative
***bowel cleanse and antibiotics prior (ex miralax)
Low anterior reception (LAR)
Preserves sphincter function
Tx colorectal cancer
Chemo
Affects all systems
Ostomy care
High fiber
Increase fluids
What is celiac
Autoimmune genetic digestive disease
Malabsorption
Inflammation w/ gluten (wheat, barley, rye)
Celiac comp
Iron anemia, vit b/d deficient leading osteoporosis
Celiac s/s
Chronic diarrhea Steatorrhea (pale frothy floating poop) bc impaired fat absorb Abd pain, distention, N/V, constipation Growth fail (lack energy/appetite) Bruising/anemia Tetany Dehydration Hair thinning

Celiac tx
Only 100% gluten free + steroids short term Vitamins Replace w/ corn & rice Low fat Compliance
Celiac crisis
Dehydration
Profuse watery diarrhea
Emotional disturb
Infection

Sacs in sigmoid no inflame or symptoms
Vague abd pain, bloating, flatulence, change bowel
Some bleeding

Pancreatitis interventions
Pain NG auction NPO (maybe ppn) Semi fowlers Antacids, PPI, H2RA Slowly advance food (high carbs!) Education (no alcohol, diet) Pancreatic enzyme meds WITH meals
Two types of IBD
Chrons and Ulcerative colitis (UC)
Chronic inflammation; exacerbations &a remission
*no cure
Diff btwn chrons and UC
Chrons- all layers bowl, anywhere in GI, skip lesions, recurrence
UC- inner layer GI, starts in rectum -> continuous, pseudopolyps, cured w surgery, cancer risk, toxic mega colon more common (perforation)
Chrons s/s
