Why is there a relative lymphocytosis in a 2 year old?
a. An absolute neutropenia occurs.
b. The absolute number of lymphocytes is increased as the immune system develops.
c. A greater proportion of neutrophils are marginated.
d. Fewer lymphocytes are marginated.
ANS: B
An absolute increase in lymphocytes occurs, presumably because the immune system is developing as more antigens are encountered; this increases the absolute number of lymphocytes, as well as the relative percent. The number of marginated neutrophils is not increased; lymphocytes do not marginate.
