Answer to Question 1
Correct Answer: 1,2
Rationale 1: Immunoglobulin provides passive immunity.
Rationale 2: Maternal antibodies can provide passive immunity.
Rationale 3: Immunization provides active immunity.
Rationale 4: Active immunity results from inoculation.
Rationale 5: Blood transfusions do not provide immunity of any type.
Global Rationale: Passive immunity occurs when preformed antibodies are transferred or donated from one person to another. For example, maternal antibodies cross the placenta and provide protection for the fetus and newborn. Other examples of passive immunity include the administration of immune globulin following exposure to hepatitis, antivenins for snakebites, and sera to treat botulism, tetanus, and rabies. Immunizations and inoculations provide active immunity. Blood transfusions do not provide immunity of any type of immunity.
Answer to Question 2
Correct Answer: 3
Rationale 1: Both types of immunity respond to antigens.
Rationale 2: Active immunity might require a booster.
Rationale 3: Active immunity occurs in response to a pathogen.
Rationale 4: Most individuals are born with some passive immunity. Active immunity requires exposure to disease.
Global Rationale: The type of response induced by the real pathogen, or its vaccine, is called active immunity. During this response the body produces its own antibodies in response to exposure. Whereas some vaccinations are needed only once, most require follow-up doses, known as boosters, to provide prolonged protection. Passive immunity occurs when preformed antibodies are transferred or donated from one person to another. Most individuals are born with some passive immunity. Both types of immunity respond to antigens.
