A nurse is caring for a patient with a large burn injury. Which skin function is most compromised in this scenario?

A. Activating B cells and other immune cells: Helper T cells coordinate the immune response by releasing cytokines that stimulate B cells to produce antibodies and activate cytotoxic T cells and macrophages, enhancing both humoral and cell-mediated immunity.

B. Producing antibodies: Antibodies are produced by plasma cells, which are differentiated B cells, not by helper T cells.

C. Directly killing infected cells: Cytotoxic T cells are responsible for directly attacking and destroying infected or abnormal cells, whereas helper T cells regulate and support the immune response.

D. Engulfing pathogens: Phagocytic cells such as macrophages and neutrophils perform pathogen engulfment; helper T cells do not directly ingest pathogens.

A. Neutrophils: Neutrophils are the most abundant white blood cells and are first responders to bacterial infections. They phagocytize bacteria and release enzymes to destroy pathogens.

B. Basophils: Basophils release histamine and other mediators during allergic reactions and inflammation, but they do not play a primary role in directly fighting bacterial infections.

C. Lymphocytes: Lymphocytes, including B and T cells, are central to adaptive immunity, targeting specific pathogens, viruses, and infected cells rather than providing immediate defense against bacteria.

D. Eosinophils: Eosinophils are mainly involved in combating parasitic infections and modulating allergic responses, rather than acting as primary defenders against bacteria.
