The nursing instructor is discussing immunity with her clinical group. What statement would the instructor make that would be accurate about immunity?
A) Active immunity occurs with injected antibodies that react with specific antigens.
B) Serum sickness results when the body fights antibodies injected as a form of active immunity.
C) Passive immunity occurs when foreign proteins are recognized and the body produces antibodies.
D) Passive immunity is limited, lasting only as long as the antibodies circulate.
D
Feedback:
Unlike active immunity, passive immunity is limited. It lasts only as long as the circulating antibodies last because the body does not produce its own antibodies as found in active immunity. People are born with active immunity in which the body recognizes a foreign protein and begins producing antibodies to react with specific proteins or antigens. Serum sickness is a massive immune reaction against the injected antibodies that occur with passive immunity.
