Flashcards in Blood and Lymph: Symptomatic & Diagnostic Terms Deck (49):
1

the presence of small red blood cells

microcytosis

2

the presence of large red blood cells

macrocytosis

3

the presence of red blood cells of unequal size

anisocytosis

4

the presence of large, irregularly shaped blood cells

poikilocytosis

5



an increase in the number of immature erythrocytes in the blood

reticulocytosis

6

an abnormally reduced number of red blood cells

erythropenia

7

an abnormally reduced number of lymphocytes

lymphocytopenia

8

a decrease in the number of neutrophils

neutropenia

9

an abnormally reduced number of all cellular components in the blood

pancytopenia

10

breakdown of the red blood cell membrane

hemolysis

11

impaired immunological defenses caused by an immunodeficiency disorder or therapy with immunosuppressive agents

immunocompromised

12

impaired ability to provide an immune response

immunosuppression

13

the presence of enlarged (diseased) lymph nodes

lymphadenopathy

14

enlargement of the spleen

splenomegaly

15

-acquired immunodeficiency syndrome
-a syndrome caused by HIV(human immunodeficiency virus that renders immune cells ineffective permitting opportunistic infections, malignancies, and neurological diseases to develop; it is transmitted sexually or through exposure to contaminated blood

AIDS

16

a condition in which there is a reduction in the number of red blood cells, the amount of hemoglobin, or the volume of packed red cells in the blood, resulting in a diminished ability of the red blood cells to transport oxygen to the tissues

anemia

17

a normocytic normchromic type of anemia characterized by the failure of the marrow to produce red blood cells

aplastic anemia

18

a microcytic-hypochromic type of anemia characterized by a lack of iron affecting the production of hemoglobin and characterized by small red blood cells containing low amounts of hemoglobin

iron deficiency anemia

19

a macrocytic-normchromic type of anemia characterized by an inadequate supply of vitamin B12, causing red blood cells to become large, varied in shape, and reduced in number

pernicious anemia

20



any disorder characterized by abnormal function of the immune system that causes the body to produce antibodies against itself, resulting in tissue destruction or loss of function; rheumatoid arthritis and lupus are examples of autoimmune diseases

autoimmune disease

21



a disorder that results from the incompatibility of a fetus with an Rh-positive blood factor and a mother who is Rh-negative, causing red blood cell destruction in the fetus; necessitates a blood transfusion to save the fetus

erythroblastosis fetalis

22

the presence or lack of antigens on the surface of red blood cells that may cause a reaction between the blood of the mother and the fetus, resulting in fetal anemia

Rh factor

23

the presence of antigens

Rh positive

24

the absence of antigens

Rh negative

25

a hereditary disorder that results in excessive build up of iron deposits in the body

hemochromatosis

26

a group of hereditary bleeding disorders in which there is a defect in the clotting factors necessary for the coagulation of blood

hemophilia

27



a chronic or acute malignant disease of the blood-forming organs, marked by abnormal leukocytes in the blood and bone marrow; classified according to the types of white cells affected

leukemia

28



a disorder within the bone marrow characterized by the proliferation of abnormal stem cells; usually develops in a specific type of leukemia

myelodysplasia

29

any neoplastic disorder of the lymph tissue, usually malignant, as in Hodgkin's disease

lymphoma

30

the process by which cancer cells are spread by blood or lymph circulation to distant organs

metastasis

31

a condition caused by the Epstein-Barr virus characterized by an increase in mononuclear cells (lymphocytes and monocytes) in the blood, along with enlarged lymph nodes (lymphadenopathy), fatigue, and sore throat (pharyngitis)

mononucleosis

32

an increase in the number of erythrocytes and hemoglobin in the blood

polycythemia

33



a systemic disease caused by the infection of microorganisms and their toxins in the circulating blood

septicemia

34

a bleeding disorder characterized by an abnormal decrease in the number of platelets in the blood, which impairs the clotting process

thrombocytopenia

35

CBC

-complete blood count
-the most common laboratory blood test performed as a screen for general health or for diagnostic purposes; includes RBC, WBC, HGB, and Hct

36

RBC

-red blood count
-a count of the number of red blood cells per cubic mm obtained by a manual or automated laboratory method

37

WBC

-white blood count
-the number of white blood cells per cubic mm obtained by manual or automated laboratory methods

38

HGB

a test to determine the blood level of hemoglobin

39

HCT

-hematocrit
-a measurement of the percentage of packed red blood cells in a given volume of blood

40

PLT

-platelet count
-a calculation of the number of thrombocytes in the blood: normal ranges from 150,000-450,000/cubic mm

41

ESR

-erythrocyte sedimentation rate
-a timed test to measure the rate at which red blood cells settle or fall through a given volume of plasma

42

PTT

-partial thromboplastin time
-a test to determine coagulation defects such as platelet disorders
(thromboplastin=a substance present in tissues, platelets, and leukocytes that is necessary for coagulation)

43

PT

-prothrombin time
-a test to measure the activity of prothrombin, a protein substance in the blood that is essential to the clotting process, in the blood

human immunodeficiency virus
