Chapter 30: Alterations of Leukocyte,
Lymphoid Function UPDATED Exam
Questions and CORRECT Answers
what are the two types of leukocyte malfunction disorders - CORRECT ANSWER -
qualitative leukocyte disorders
quantitative leukocyte disorders
which type of alteration in leukocyte function results from decreased production in the bone
marrow or accelerated destruction of cells in the circulation - CORRECT ANSWER -
quantitative leukocyte disorders
which type of alteration in leukocytes consists of disruptions of leukocyte function - CORRECT
ANSWER - qualitative leukocyte disorders
what is a reduced number or quality of leukocytes - CORRECT ANSWER - leukopenia
what is an increased number of leukocytes - CORRECT ANSWER - leukocytosis
what are the causes of alterations in leukocytes - CORRECT ANSWER - infection
bone marrow dysfunction or premature destruction of cells
phagocytic cells may lose their function
lymphocytes may lose their capacity to respond to antigens
which alteration in leukocyte function involves higher leukocyte counts than normal, is a normal
protective response to physical or emotional stress, surgery, pregnancy, or infection, and can be
pathological - CORRECT ANSWER - leukocytosis
, which type of alteration in leukocyte function involves counts that are lower than normal, is
always abnormal, can be caused by radiation, shock, and autoimmune disease, and predisposes a
person to infection - CORRECT ANSWER - leukopenia
what is the abnormally low leukocyte count that qualifies as leukopenia - CORRECT
ANSWER - less than 4000 cells/mm3
what is the primary cause of increased numbers of circulating granulocytes - CORRECT
ANSWER - primarily a response to infection
what types of cells are granulocytes - CORRECT ANSWER - neutrophils
eosinophils
basophils
what is another term that may be used to describe granulocytosis and why - CORRECT
ANSWER - neutrophilia
because neutrophils are the most numerous granulocytes
what is an increase in the number of circulating granulocytes - CORRECT ANSWER -
granulocytosis
what is the premature release of the immature white blood cells that occurs when the demand for
circulating mature neutrophils exceeds the supply - CORRECT ANSWER - shift to the left
OR
leukemoid reaction
what is a condition associated with a reduction in the number of circulating neutrophils -
CORRECT ANSWER - neutropenia
