A nurse is caring for a client who had an anaphylactic reaction after a blood transfusion. The nurse reviews the literature to further understand antibody-mediated immunity (AMI). Which of the following information should the nurse confirm about AMI?

AMI is mediated by antibodies produced by B-lymphocytes.

AMI defends only against viral infections.

Humoral immune response is mediated by T-lymphocytes.

AMI involves phagocytic natural killer cells.

Answer and Explanation

The Correct Answer is A

A. Antibody-mediated immunity (AMI) is primarily the result of antibodies produced by B-lymphocytes in response to antigens. This immune response is essential for protecting the body against pathogens and is particularly important in transfusion reactions.

B. While AMI is crucial in defending against various infections, it is not limited to viral infections; it also plays a significant role in protecting against bacterial infections and other types of pathogens.

C. The humoral immune response is mediated by B-lymphocytes, while T-lymphocytes are primarily involved in cell-mediated immunity, which targets infected cells and regulates immune responses.

D. Phagocytic cells, such as macrophages and neutrophils, are involved in the innate immune response, not directly in antibody-mediated immunity. Natural killer (NK) cells are part of the innate immune system and target virus-infected cells and tumors, but they do not mediate AMI.
