Which of the following individual situations listed below best exemplifies the processes of innate immunity?
A)
A child who has experienced heat and swelling of his skinned knuckle
B)
An adult who complains of itching and is sneezing because he is allergic to pollen
C)
A client whose blood work indicates increased antibody titers during an acute illness
D)
A client who has experienced rejection of a donor liver after transplantation
Ans:
A
Feedback:
In a skinned knuckle, one of the body's main innate defenses, the skin, is breached. The heat and swelling that accompany a breach in the skin are inflammatory responses, part of the body's innate immune defenses. Allergies are an inappropriate adaptive response mediated by immunoglobulin E; antibody titers increase during illness in response to the infection; and transplanted organs are rejected because the organ is recognized as foreign. These are all aspects of specific, acquired immunity.
