Liver Disease Flashcards
Ascites: Causes & S/Sx
Causes:
- Portal hypertension
- Changes in ability to metabolize aldosterone, increases fluid retention
- Albumin moves into peritoneal cavity
S/Sx:
- Striae
- Distended veins
- Umbilical hernia
Ascites: Treatment & Nursing Management
- Paracentesis (administer albumin after to prevent circulatory & renal dysfunction)
- Low-sodium diet
- Diuretics (spironolactone #1, furosemide)
- Salt-poor albumin
- TIPS or Transjugular Intrahepatic Portosystemic Shunts (procedure to connect portal veins to lower BP)
- Record abdominal girth, daily weights, I&O’s
Esophageal Varices: Causes & S/Sx
Causes:
- Cirrhosis
S/Sx:
- Hematemesis
- Melena
- Deterioration & shock
Esophageal Varices: Treatment (including meds & procedures)
- Treat shock
- Oxygen
- IV F&E, volume expanders
- Blood
Medications:
- Vasopressin & somatostatin (octreotide): decrease bleeding (octreotide > vasopressin)
- Nitroglycerin (with vasopressin): reduce coronary vasoconstriction
- Propranolol & nadolol: decrease portal pressure
- Isosorbide dinitrate
Procedures:
- Balloon tamponade (direct pressure on bleeding)
- Endoscopic sclerotherapy (injection to control bleeding)
- Esophageal banding (strangles veins to prevent bleeding)
Esophageal Varices: Nursing Management
- Monitor patient condition (including emotional response, cognitive status)
- Monitor for complications:
- Hepatic encephalopathy resulting from bleeding in GI tract
- Delirium related to alcohol withdrawal
- Tube care, GI suction, oral care
- Measures to reduce anxiety & agitation
- Education
Hepatic Encephalopathy: Causes & S/Sx
Causes: Accumulation of ammonia & other toxic substances in the blood
S/Sx:
- Mental status changes & motor disturbances
- Alterations in mood & sleep (insomnia, restlessness)
- Potential seizures, coma
- Fetor hepaticus (musty, sweet odor from patient’s breath)
- Asterixis (involuntary flapping of hands)
Hepatic Encephalopathy: Treatment
Lower ammonia levels:
- Lactulose
- Gastric suction, enemas, oral Abx (in GI tract)
- Neomycin, metronidazole, rifaximin (reduce ammonia-forming bacteria in colon)
- IV glucose to reduce protein levels
Hepatic Encephalopathy: Nursing Management
- Assess neurological status frequently
- Mental status monitored by daily record of handwriting
- Monitor serum ammonia levels (15-45)
- Discontinue sedatives, analgesics, tranquilizers
- Protein restriction (1.2-1.5 g/kg/day)
Identify the labs assessed for liver dysfunction and damage.
- ALT (8-40): Primary liver injury indicator
- AST (10-40): Less specific
- GGT, GGTP (must be elevated with ALT or AST to indicate liver disease)
- LDH (lactate dehydrogenase)
- Protein, alkaline phosphatase (ALP), ammonia, albumin
- Bilirubin
- PT and INR (elevated; liver not producing enough vitamin K)
- Cholesterol
Identify supplements that are often added to an ESLD patient’s IV fluids.
- Glucose: reduce protein levels
- Vitamin A, B, C, K
- Steatorrhoea → give Vit. A, D, E (fat-soluble)
- Folic acid → treat potential bleeding
- Electrolytes to treat imbalance (K)
Identify safety risks for ESLD patients.
- Activity tolerance related to fatigue
- Impaired skin integrity (turn frequently to prevent pressure injuries)
- Risk for injury & bleeding (prevent falls, give Vit K)
- Risk for seizures
- Imbalanced nutrition (give vitamins, supplements)
- Acute confusion
- Risk for aspiration (coma; inability to respond to stimuli)
What is the most common surgical procedure for liver cancer?
Lobectomy
Removal of a lobe of the liver
Hepatitis A: Causes & Most at Risk
Causes:
- Poor hand hygiene
- Fecal-oral route (ingestion of food or liquids)
- Sexual activity
(NOT blood)
Most at Risk:
- Homeless
Hepatitis B: Causes & Most at Risk
Causes:
- Blood, saliva, semen, vaginal secretions
- Mothers to infants
Most at Risk:
- Exposure to blood or bodily fluids
- Hemodialysis, IV/injection drug use
- Multiple sexual partners
- STI (recent)
Hepatitis C: Causes & Most at Risk
Causes: Blood, contaminated needles (sex uncommon)
Most at Risk:
- Contaminated
- Multiple sex partners
- Patients receiving frequent blood transfusions
Interferon treatment, no vaccine
