25
Disease progression for Hep A
- Avoid alcohol and drugs that may be hepatotoxic (acetaminophen) - Best rest, nutrition, IV fluid if needed (home care)
26
Prevention of transmission for Hep A
- Meticulous hand washing - Proper sewage disposal - Vaccination (HAV) - Avoid sharing eating utensils, bath towels, and other personal care items - Safe sexual practices
27
HAV is from what virus?
RNA virus
28
HBV is from what virus?
DNA virus
29
What hep is transmitted in blood and body fluids?
Hep B
30
What are the main transmission issues for HBV?
- Contaminated equipment (dialysis) - IV drug abuse - Sexual activity - Blood products
31
Risk factors for HBV
- Healthcare workers - Exposure to blood products - Close contact with carrier - IV injection drug use - Multiple partners - Mom-child - STD - Tattoo - Travel
32
Hep B diagnostics
- HBsAG - Anti-HBs
33
When is HBsAG detectable?
1-10 weeks after exposure
34
We call the patient a carrier of Hep B is the HBsAG..
Shows that the antigen persists longer than 6 months
35
Anti-HBs indicate...
Immune state (some people require more than the 3 shots, myself being one of them)
36
With about 90% of exposed people to Hep B, how do they recover?
People develop antibodies and recover spontaneously in 6 months
37
What happens to about 10% of Hep B exposures?
They progress to carrier state or develop chronic hepatitis
38
What does chronic Hep B look like?
Hepatocellular injury and inflammation
39
HBV is a major cause of what?
Cirrhosis (scarring of the liver caused by many conditions) and hepatocellular carcinoma (primary liver cancer)
40
Prevention and management of Hep B
- Blood donor screening - Needless IV systems, disposable needles - Active immunity (vaccination) - Passive immunity (immune globin)
41
What active immunity do we use for prevention of Hep B?
Vaccination
42
What passive immunity do we use for prevention of Hep B?
Immune globin
43
When do we used passive immunity for Hep B?
- If exposed to HBV and not previously vaccinated - Needle stick injury, splashes in contact with mucosa, sexual contact with person who is positive, and perinatal exposure
44
Hep B med & management
- Alpha interferon - Antiviral agents for chronic HBV - Bed rest - Adequate nutrition (continuing care with home health nurse)
45
For Hep B management, how is Alpha interferon administered?
IM injection (10 million U 3x week for 16-24 weeks) - Numerous side effects
46
SE for Alpha interferon?
Fever Chills Malaise
47
What does Alpha interferon do?
Reduces inflammation of the liver, reduces the s/s
48
What antiviral agents are used for chronic HBV?
Enecavir ETV Tenofovir TDF
49
What virus does Hep C come from?
RNA virus
50
What hep is transmitted via blood contact with skin/mucous membranes?
HCV
51
Which hep has no effective treatment?
Hep C
52
What percentage of people develop chronic form of HCV?
85%
53
What is the leading cause of liver cancer and cirrhosis?
HCV
54
Hep C is the major reason for...
Most transplants
55
Which treatment is best for prevention of relapses and s/s of Hep C?
Combo of antiviral agents (Olysio, Sovaldil, Harvoni and Viekira Pak)
56
Nursing care for Hepatitis
- UNIVERSAL PRECAUTIONS ALWAYS - Prevent when possible - Rest liver and promote cell regeneration - Symptom management
57
How do we prevent hepatitis?
Careful assessment and risk identification
58
What kind of diet do we want for hepatitis?
- High CHO diet - Small frequent feedings
59
What symptom management do we use for hepatitis? What do we check?
- Meds for itching and nausea - Check metabolism of drug
60
Patient teaching of Hepatitis
- Sexuality - Liver toxins -0 May be chronic carrier - No sharing of food items, razors, toothbrushes, etc. - Proper disposal of instruments/sharps- Cannot be blood donor if HBsAG+
61
You cannot be a blood donor if...
HBsAG is positive
