  1. Major fxn of gall bladder
    to concentrate and store bile....constantly filling and emptying
  2. What causes obstruction of the gall bladder?
    stones migrating and lodging in the neck of the gall bladder, cystic duct or common bile duct
  3. Cholestasis definition

    S/S
    any condition in which the flow of bile from the liver is slowed or blocked.

    • S/S-clay or white colored stools
    • dark urine
    • cant digest certain foods
    • itching
    • nause
    • vomit
    • PAIN in right upper abdomen
    • YELLOW skin or eyes
  4. Result of bile not being able to flow....
    bile is an irritant, causes inflammation and this inflammation can spread to other organs...pancrease=pancreatitis
  5. What causes peritonitis?
    bile and impaired circulation from swelling causes ischemia, leading to abscess formation and then necrosis of the GB wall and gangrene

    Perforation then occurrs and you have peritonitis
  6. Cholangitis
    infection of the common bile duct by bacteria from other parts of the body....got there by lymph channels

  15. What's viral hepatitis
    There are 6 types...ABCDEG
  16. Patho of Hepatitis
    • Virus replicates and attacks hepatocytes
    • liver becomes enlarged and congested with inflammatory cells, lymphocytes and edema
    • Swelling causes obstruction to the portal circulation with interference to the blood flow in to the hepatic lobules
    • edema of liver bile channels results in intrahepatic obstructive jaundice
  17. Why does the livers normal lobular pattern become distored?
    Increasing inflammation, necrosis and regneration of cells causes this
  18. How do you know that the liver is in recovery phase from hepatitis?
    • active phagocytosis
    • removal of damaged liver cells
    • regeneration of liver cells

    Takes 2-3 months
  19. What will happen if liver cells dont regenerate with ongoing necrosis?
    death
  20. Hepatitis A Antigen (HAV)
    Describe

    • Icteric Phase
    • Post Icteric Phase
  59. "icteric" means
    jaundice

    ANOREXIA & FATIGUE
  61. Icteric Phase
    Starts when and lasts?
    S/S:
    starts in 2 weeks and lasts 4-6 weeks

    Worsening of anorexia, nausea, starts vomiting, weakness and maliaise, liver tenderness NOW JAUNDICE
  62. What causes jaundice?
    Increased amt of bilirubin in serum

    when the liver's bile channels are obstructed, the concentration of bilirubin in the blood becomes abnormally high, excess bilirubin collects in the dermis and epidermis and in the connective tissue of the sclera creating yellow of jaundice
  63. S/S of jaundice:
    • yellow sclera and skin
    • elevated total bilirubin in serum
    • dark amber, foamy urine

  64. What causes pruritis
    irritation of bile salts on the skin
  65. How can you tell if there is liver damage?
    • Liver function tests.....look at:
    • Elevated ALT and AST enzymes
    • Elevated Alkaline Phosphate
  66. Why does alkaline phosphate elevate with liver problems
    it is made in the bones, kidney, liver and intestines and is excreted thru the biliary tract.  When it is blocked, levels rise
  67. What does liver damage to do PT and PTT?
    will prolong PT first and cause clotting time to increase.

    PTT will increase with severe liver damage

    Clotting factors are synthesized in the liver and will be decreased with liver damage causing few clotting factors therefore prolonged clotting times and high risk bleeding
  68. What does liver damage do to albumin?
    it is made in the liver too...so will have decreased levels of this which means a potential for drug problems
  69. When will direct (conjugated-in water soluble form) bilirubin levels be elevated?
    during any condition that obstructs blood flow.

    • Such as:
    • hepatitis
    • cirrhosis
    • gallstones
    • tumor
    • Anything that damages liver cells
  70. When will indirect bilirubin increase?
    Only when the person is having a problem with destruction of RBC's.  Like in Anemia or Rh problems in newborn.

    NOT with Hepatitis
  71. When a person has Hepatitis A, B, C and D....what serologic test will be abnormal?
    WBC
  72. Post-icteric phase
    How long does it last?
    What is it?
    Lasts several weeks to months and is when complications of Hepatitis occurs....cuz it is when chronic forms develop

    • Liver inflammation that lasts longer than 6  months. 
    • Mile or no symptoms, no further destruction after initial insult

    • Likelihood:
    • HBV 1-10% adults or 15-80% in newborns

  74. Why would a person with HBV or HCV become chronic?
    • increased physical exertion
    • Alcohol intake
  75. Chronic Active Hepatitis B,C,D
    is liver damage that can lead to hepatic necrosis and cirrhosis (fibrotic liver disease)
  76. What does Cirrhosis (Fibrotic liver disease) cause?
    • Fulminant Hepatitis-it is the failure of liver cells to regenerate
    • Progressive necrosis and damage leads to liver failure.
    • Fatal form is rate....but once develop fatal form-1 yr to live
  77. S&S of liver failure
    • rapid weight gain from fluid collection with ascites

    • edema in legs
    • cardiac damage
  78. ascites
    accumulation of fluid in peritoneal cavity
  79. Why dont ascites get drained very often?
    cuz the fluid has lots of albumin in it....will drain it if they cant breathe.

    Push on beer belly, get a fluid wave...ascites
  80. Which hepatisis is linked to Primary liver carcinoma (Hepaticellular carcinoma)
    Hepatitis B and C
  81. How does liver failure cause hepatic encephalopathy
    toxins in the blood go to the brain....
  82. Nandas:
    • Activity intolerance
    • Risk for fluid volume imbalance
    • Risk for injury: bleeding (no clotting)
    • Imbalanced nutrition
    • Risk for impairment of skin integrity(pruritis)
    • Risk for social isolation (Hep A....cant work in restaurant)
  83. What do you do to treat Hepatitis?
    • No cure!!
    • Fluid and elctrolyte replacement
    • Vitamin K-for clotting
    • Antihistamines-pruritis
  84. Alpha Interferon treats what?
    How?
    • Hepatitis B and C
    •  by stopping viral replication
  85. Epivir
    Treats what?
    How?
    antiviral drug used to treat HBV

    Used in conjunction with Interferon

    Stops replication, which decreases viral load which decreases liver damage

    Watch OTC's that are known to cause liver damage

    • Tylenol

    have an antibody titer drawn 1-2 months after the 3rd injection.  If ok you are protected for life, if not, booster is needed
  99. Post exposure to Hepatitis B...what do you do?
    HBIG within 7 days then get Recombivax series
