26
Chronic phase of Hepatitis | Lasts?
weeks to months
27
Chronic phase of Hepatitis A.K.A?
post-icteric, convalescent
28
Liver biopsy pre-procedure diagnostics?
- coagulation status | - Blood-T&CM
29
Liver biopsy procedure diagnostics?
- Position supine/left lateral | - hold breath after expiration for needle insertion
30
Liver biopsy post-procedure diagnostics?
- Lie on right side to splint area, pillow under costal margin, bedrest 12 hours - Monitor for hemorrhage, peritonitis
31
Therapy: Acute Hepatitis
- Adequate nutrition - Hydration - Rest - No specific drug therapies - Support therapy - Antiemetics
32
Chronic Hepatitis B treatment focuses on?
- ↓ Viral load - ↓ Liver enzyme levels - ↓ Rate of disease progression - ↓ Rate of drug-resistant HBV
33
Side effects of peginterferon alfa-2a?
Flu like symptoms, depression, hair thinning, diarrhea, insomnia
34
Lamivudine (Epivir)
- Tx for Hep B - PO daily - Caution in those with renal impairment
35
Adefovir (Hepsera)
- Tx for Hep B - PO daily - For Lamivudine resistant HBV - is Nephrotoxic
36
Nucleoside and nucleotide analog drugs to treat Hep B?
- Lamivudine - Adefovir - Entecavir
37
drugs to treat Hep C?
peginterferon alfa-2a with ribavirin
38
Ribavirin use?
used with peginterferon to treat Hep C
39
Ribavirin side effects?
- used to tx Hep-C - Anemia - anorexia - cough - rash - pruritus - dyspnea - insomnia - teratotoxicity
40
Complications for Hep C?
- Chronic liver disease - Cirrhosis - Hepatocellular carcinoma
41
Chronic progressive disease of the liver characterized by diffuse degeneration and destruction of hepatocytes
Cirrhosis, repeated destruction cause scar tissue to form
42
Major complications of cirrhosis?
- portal HTN - esophageal and/or gastric varices - peripheral edema and ascites - hepatic encephalopathy (mental status changes, including coma) - hepatorenal syndrome
43
Compensated vs decompensated cirrhosis?
- compensated = no complications | - decompensated = 1 or more complications
44
Causes/types of Cirrhosis?
- Alcoholic cirrhosis - Hepatitis cirrhosis - Complication of viral, toxic, or idiopathic hepatitis - Nonalcoholic Fatty Liver Disease (NAFLD) - History of diabetes or metabolic syndrome - Biliary cirrhosis - Associated with chronic biliary obstruction - Cardiac cirrhosis - From long-standing severe right-sided heart failure
45
Diagnostics for Cirrhosis?
- Liver function tests - Serum electrolytes - CBC, PT - Serum albumin - Liver ultrasound - CT - Endoscopy - Liver biopsy
46
Early Manifestations of Cirrhosis?
- Anorexia - Dyspepsia - Flatulence - N/V - Bowel changes - Fever - Abdominal pain
47
Late Manifestations of Cirrhosis
- Jaundice- can't excretet bilirubin - Skin Lesions-dilated blood vessels - Hematological problems - thrombocytopenia, - leukopenia - anemia - coagulation disorders - Endocrine problems - gynecomastia - Peripheral neuropathy - dietary deficiency of thiamine, folic acid and cobalamin
48
Portal hypertension is characterized by?
- Increased portal venous pressure (caput medusa and hemrrhoids) - Splenomegaly - Large collateral veins - Ascites - Gastric and esophageal varices
49
Accumulation of serous fluid in the peritoneal cavity
ascites
50
ascites
- Accumulation of serous fluid in the peritoneal cavity - Abdominal distention with weight gain - Common manifestation of cirrhosis
51
peripheral edema in cirrhosis is cause by?
decreased colloidal oncotic or colloidal osmotic pressure
52
What causes hepatic encephalopathy in cirrhosis?
- increased ammonia levels due to inability of liver to convert ammonia to urea - ammonia crosses the BBB and causes neurotoxicity
53
S/S of hepatic encephalopathy?
- Changes in neurologic and mental responsiveness - Impaired consciousness and/or inappropriate behavior - Sleep disturbances to lethargy to coma - Asterixis (flapping tremors) - Fetor hepaticus (musty sweet odor on breath)
54
musty sweet odor on breath cause by hepatic encephalopathy and portal HTN?
Fetor hepaticus
55
flapping tremors caused by hepatic encephalopathy?
Asterixis
56
Renal failure with advancing azotemia, oliguria, and intractable ascites
Hepatorenal Syndrome
57
Hepatorenal Syndrome
- Renal failure with advancing azotemia, oliguria, and intractable ascites - No structural abnormalities
58
high levels of nitrogen containing compounds in the blood?
azotemia
59
Treatment: Ascites
- ow NA - Diuretics - Paracentesis - Peritoneovenous shunt
60
Continuous reinfusion of ascitic fluid from the abdomen to the vena cava
Peritoneovenous shunt
61
Peritoneovenous shunt
Continuous reinfusion of ascitic fluid from the abdomen to the vena cava
62
Meds to treat an acute varices bleed?
- Vitamin K - Octreotide - Vasopressin (with NTG)
63
Non-med Treatment: Varices
- Endoscopic ligation - Endoscopic sclerotherapy - Balloon tamponade
64
Medications-long-term management of varices?
Propanolol (Inderal)
65
- Tract (shunt) between systemic and portal venous system - Decreases portal venous pressure and decompresses varices - non surgical tx
Transjugular intrahepatic portosystemic shunt (TIPS)
66
Transjugular intrahepatic portosystemic shunt (TIPS)
- Tract (shunt) between systemic and portal venous system - Decreases portal venous pressure and decompresses varices - non surgical tx
67
Surgical Tx of Varices 1) decreases bleeding 2) leaves portal venous flow intact
1) Portacaval shunt | 2) Distal splenorenal shunt
68
medication that traps Ammonia (NH3 ) in gut?
Lactulose (Cephulac)
69
Lactulose (Cephulac)
- medication that traps NH3 in gut | - Decreased medication compliance due to severe diarrhea
70
Alternative medication for Lactulose to treat Hepatic Encephalopathy?
Neomycin and Rifaxamin
71
Acute Nursing Interventions for cirrhosis?
Rest, Nutrition, Fluid, Electrolytes, Accurate I/O, Daily weights, Abdominal girth, Paracentesis
72
Nutritional Therapy - Cirrhosis without complications?
- High in calories (3000 cal/day) - ↑ Carbohydrate - Moderate to low fat - Protein restriction rarely justified
