(ATI/HESI question from external source) Which statement is true regarding hepatitis A vaccine?
It provides passive immunity for up to 6 months.
It is recommended for travelers to areas with high prevalence of hepatitis A.
It is not effective in preventing hepatitis A in close contacts of infected individuals.
It should be given to newborns of hepatitis A positive mothers within 12 hours of birth.
The Correct Answer is B
A.
Choice A rationale:
Choice A is incorrect because the hepatitis A vaccine provides active immunity, not passive immunity. Active immunity means that the body produces its antibodies in response to the vaccine, providing long-term protection against the virus.
Choice B rationale:
The hepatitis A vaccine is indeed recommended for travelers to areas with high prevalence of hepatitis
A. It helps protect travelers from acquiring the virus through contaminated food and water in regions where hepatitis A is more common.
Choice C rationale:
Choice C is incorrect because the hepatitis A vaccine is effective in preventing hepatitis A in close contacts of infected individuals. Vaccination is a crucial preventive measure for those who are in close contact with infected individuals, as it can help halt the spread of the virus.
Choice D rationale:
Choice D is incorrect because the hepatitis A vaccine is not given within 12 hours of birth to newborns of hepatitis A positive mothers. The vaccination schedule for hepatitis A vaccine varies depending on the country's recommendations but is typically given starting at 12-23 months of age.

Correct Answer is A
Explanation
Choice A rationale:
Getting vaccinated with the hepatitis B vaccine is an effective prevention strategy for hepatitis
B. It helps protect the individual from acquiring the virus and developing the disease. Vaccination is crucial, especially for individuals at risk of exposure to the virus, such as healthcare workers, sexually active individuals, and household contacts of infected individuals.
Choice B rationale:
Drinking alcohol occasionally is not a safe practice for individuals with hepatitis
B. Alcohol can further damage the liver and worsen the condition. Avoiding alcohol entirely is essential to protect the liver and promote healing.
Choice C rationale:
Clearance of infection does not confer immunity to hepatitis
B. The patient should still take precautions to prevent potential reinfection through sexual contact or other means.
Choice D rationale:
Screening blood donors and recipients for HBV infection is necessary to prevent the transmission of the virus through blood transfusions. It is a crucial safety measure to ensure that blood and blood products are free from hepatitis B virus and other infectious agents.
Correct Answer is ["A"]
Explanation
Choice A rationale:
Advising the patient to avoid alcohol and hepatotoxic drugs is appropriate because in hepatitis A, the liver is already inflamed and compromised. Alcohol and hepatotoxic drugs can further damage the liver and impede the healing process. It is essential to protect the liver from further harm during recovery.
Choice B rationale:
The patient has hepatitis A, not hepatitis C, so there is no need for the hepatitis C vaccine. The hepatitis A vaccine is available for prevention, not the hepatitis C vaccine.
Choice C rationale:
While monitoring liver function is essential for individuals with liver disease, this statement is not specifically relevant to the patient with hepatitis
A. Monitoring liver function is more critical for chronic liver diseases like hepatitis B and C.
Choice D rationale:
Antiviral therapy is not indicated for hepatitis A since the infection usually resolves on its own. This statement is not appropriate for the patient with hepatitis
