Final answer:
Immune serum globulin for passive immunization is used in cases like hepatitis exposure and administration of tetanus antitoxin, providing immediate but temporary protection against these diseases without generating long-term immunity.
Step-by-step explanation:
Immune serum globulin is given for passive immunization in cases where immediate protection against specific diseases is needed. It is an artificially acquired form of passive immunity, which can be used both prophylactically, to prevent disease after exposure to a pathogen, and therapeutically, to treat an active infection. The correct answer to the question is hepatitis exposure, and tetanus antitoxin, as these are examples where immune serum globulin would be used for passive immunization.
Artificial passive immunity does not stimulate the recipient's own immune system to create memory cells; therefore, it provides immediate but temporary defense. The recipient benefits from the donor's antibodies to fight infections or neutralize toxins, such as in the case of hepatitis exposure, where the body receives antibodies against the hepatitis virus, and in the administration of tetanus antitoxin to neutralize the toxins produced by Clostridium tetani.
