Viral hepatitis: precautions by type, vaccination, rest, nutrition and teaching
- Safe practice
In viral hepatitis the type sets the precautions: stool for A and E, blood for B, C and D; vaccines exist for A and B, and C can be cured.
What it is
Viral hepatitis is liver inflammation caused by the hepatitis A, B, C, D or E viruses. They differ in how they spread, which sets the nursing precautions and the teaching. Acute hepatitis is mostly managed with supportive care; chronic hepatitis B and C need linkage to care and long follow-up. The nurse applies the right precautions, supports rest, food and fluids, protects staff and contacts, checks vaccination and teaches how to avoid passing the virus on.
What it requires
- Knowing the virus type, because it sets the precautions.
- Hand washing with soap and water after the toilet or a nappy change and before handling food.
- Safe use and disposal of sharps, and the exposure protocol.
- The vaccination status of the patient, contacts and staff.
How it is applied (and why)
- Apply standard precautions with every patient — B and C spread through blood, often without symptoms.
- Add contact precautions for a diapered or incontinent patient with A or E — the virus is in the stool.
- Teach hand washing after the toilet or nappy changes and before preparing or eating food — it blocks the main route of A.
- Use and dispose of sharps safely and follow the exposure protocol — needlesticks transmit B and C.
- Teach: no sharing razors, toothbrushes or injection equipment; condoms for sex — these spread B and C.
- Support rest, a balanced diet and fluids; record intake and vomiting — care in acute hepatitis is supportive.
- Report worsening jaundice, persistent vomiting or any new change in the patient's condition — severe acute hepatitis can lead to liver failure.
- Check vaccination and refer contacts as the protocol says — hepatitis A vaccine within 2 weeks of exposure can protect.
- For chronic B or C, teach follow-up and adherence — treatment prevents liver damage and cancer.
In nursing practice
- Hepatitis B caught in infancy becomes chronic in about 95 % of cases, against less than 5 % in adults: hence the birth dose.
- Most people with hepatitis C have no symptoms, so testing is what finds it.
- Chronic hepatitis B treatment is usually lifelong once started.
- Hepatitis A is not chronic, but older adults and people with liver disease can become very ill.
- Hepatitis B passes mostly from mother to child at birth; the birth dose, with antiviral medicines in pregnancy when indicated, reduces it.
Common mistakes
- Using contact isolation for hepatitis B or C instead of reliable standard precautions.
- Forgetting contact precautions for an incontinent patient with hepatitis A or E.
- Delaying the report of a needlestick.
- Missing the newborn's hepatitis B dose in the first 24 hours.
Test yourself
Think of the answer, then tap the question to see it.
Which precautions does a patient with hepatitis B need in hospital?
Standard precautions. Hepatitis B spreads through blood and body fluids, so safe sharps handling and protective equipment for exposure are key; no isolation room is needed.
When does a patient with hepatitis A need contact precautions?
When diapered or incontinent, because the virus is shed in the stool; otherwise standard precautions apply.
Which types of viral hepatitis have a vaccine?
Hepatitis A and B. There is no vaccine for hepatitis C.
When is the first hepatitis B vaccine dose given to a newborn?
Within 24 hours of birth, because infection in infancy becomes chronic in most cases.
