A registered nurse is teaching a student nurse about the causes of IgA deficiency. Which statement by the student indicates the need for further teaching? a. "IgA deficiency is a secondary immunodeficiency." b. "IgA deficiency can be caused by captopril." c. "IgA deficiency can be caused by exposure to benzene." d. "IgA deficiency can be caused by cytomegalovirus infection." e. "IgA deficiency does not mean inadequate IgM and IgG levels are present."

Selective IgA deficiency is primary and non-secondary immunodeficiency, so if a student says LgA deficiency is a secondary immunodeficiency, we can conclude that this student needs further study of the disease.

This immunodeficiency causes individuals to be deficient in the production of immunoglobulin A, the result of which is that infected people have immunity problems and may have serious infections in the mouth, airway and digestive tract.
