wt loss, dyspepsia, abdominal pain, fever, anorexia, flatulence, changed bowel habit (steatorrhea)
def: excessive accumulation of lipids w/in the hepatic cells due to increased blood glucose, increased synthesis of fatty acids, and decreased lipoprotein release.

def: accumulation of free fluid in the peritoneal cavity.
ascites
What vital signs do you want to watch for when doing a paracentesis?
*BP and HR; Hypotension and tachycardia from hypovolemia from lots of fluid being removed
What needs to be done before the patient gets a paracentesis?
Void or have a draining foley to avoid rupturing bladder.
What is caused from retention of bile due to obstruction or infection of the bile ducts?
biliary cirrhosis
why does portal hypertension cause splenomegaly?
Because blood flow is not going thru the liver as much as it should be, it stays and spleen becomes enlarged and congested. RBCs, WBCs, and platelets start to die off.
What is the nursing management for excess fluid volume from liver failure?
Daily weights and measure abdominal girth. Fluid and Na restriction, diuretics.
Why does liver failure cause weight loss?
From malnutrition because the liver is unable to metabolize carbs and fats, leading to changed bowel habits such as steatorrhea from malabsorption. Can't absorb fat soluble vitamins. Also, muscle protein is converted into glucose.
def: sudden renal failure from hepatic failure.
hepatorenal syndrome/ HRS
What nursing care do you do for hypoglycemia in liver failure?
Give D50 amp
Why does someones with liver failure bruise or bleed easily?
Because they are unable to absorb vitamin K in the intestines which produces clotting factors, and platelets are decreased from spenomegaly.

Lactulose is converted to lactate in the bowel increasing acidity of the bowel. This keeps the ammonia in the colon and prevents it from transferring into the blood.
what is a disadvantage for having a TIPS/ Transjugular Intrahepatic Portosystemic Shunt?
risk for hepatic encephalopathy.
