(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 B
Explanation
Choice B rationale:
Encouraging the client to rest and limit physical activity is an essential nursing intervention for a client with acute hepatitis
A. Rest is crucial for liver recovery and reducing the risk of complications. Physical activity can put additional stress on the liver and may worsen symptoms. The client should avoid alcohol and any medications that can potentially harm the liver during this period.
Choice A rationale:
Isolating the client in a negative pressure room is not necessary for acute hepatitis
A. Hepatitis A is primarily transmitted through the fecal-oral route, and standard precautions are sufficient to prevent its spread. Negative pressure rooms are usually reserved for clients with airborne infections, such as tuberculosis.
Choice C rationale:
Administering live attenuated hepatitis A vaccine is not indicated for a client with acute hepatitis
A. The vaccine is used for pre-exposure prophylaxis and is not effective in treating an active infection.
Choice D rationale:
Providing antiviral medications to treat the infection is not a standard intervention for acute hepatitis
A. Antiviral therapy is generally reserved for chronic hepatitis B and C infections and is not effective for acute hepatitis A, which usually resolves on its own with supportive care.
Correct Answer is D
Explanation
Choice D rationale:
This statement accurately differentiates between acute and chronic hepatitis. Acute hepatitis is a short-term inflammation of the liver that typically resolves within six months. It can be caused by various factors, including viral infections (e.g., hepatitis A, B, and C), alcohol consumption, or drug toxicity. On the other hand, chronic hepatitis is a long-lasting inflammation of the liver that persists for more than six months. Chronic hepatitis can result from ongoing viral infections (e.g., hepatitis B and C) or other causes, such as autoimmune diseases.
Choice A rationale:
This statement is incorrect. Acute hepatitis is a short-term condition that resolves within a few weeks to six months, while chronic hepatitis is the condition that can persist for an extended period.
Choice B rationale:
This statement is also incorrect. Acute hepatitis is primarily caused by viruses (e.g., hepatitis viruses), not bacteria. Chronic hepatitis is also related to viral infections, not bacterial infections.
Choice C rationale:
This statement is not accurate. Both acute and chronic hepatitis can have severe consequences, including liver cancer. Chronic hepatitis, especially when caused by hepatitis B or C viruses, can lead to the development of cirrhosis and increase the risk of liver cancer (hepatocellular carcinoma)
