What should be done after potential exposure to Hepatitis A?

After potential exposure to Hepatitis A, administration of immune globulin is the most appropriate action because it offers immediate protection against the virus. Immune globulin contains antibodies that can neutralize the Hepatitis A virus, thereby reducing the risk of developing the illness if administered within two weeks of exposure. This is particularly important because Hepatitis A is a contagious virus that can lead to acute liver disease, and timely intervention is crucial for effective prevention.

The other options do not provide the necessary preventative measures following potential exposure to Hepatitis A. Immediate surgery is not related to Hepatitis A management. Monitoring for symptoms may be part of follow-up care, but it does not prevent the infection from developing. Providing a blood transfusion is also not applicable since Hepatitis A is primarily transmitted through the fecal-oral route, not through blood. Hence, immune globulin stands out as the proper and effective response to reduce the likelihood of infection after potential exposure.
