A nurse is providing care for a 17-year-old boy who has experienced recurrent sinus and chest infections throughout his life and presently has enlarged tonsils and lymph nodes

B)
Transient hypoglobulinemia
C)
Common variable immunodeficiency

The lack of a terminal differentiation from B cells into plasma cells is the hallmark of common variable immunodeficiency. Recurrent infections, enlarged lymph nodes and tonsils, and IVIG therapy are also commonly associated.
