31
Q

anemia

A

blood disorder characterized by a deficiency of red blood cell production and hemoglobin, increased RBC destruction, or blood loss

32
Q

aplastic

A

failure of bone marrow to produce stem cells because it has been damaged by disease, cancer, radiation, or chemotherapy drugs; rare but serious form of anemia.

33
Q

pernicious

A

deficiency of erythrocytes resulting from inability to absorb vitamin B12 into the body, which plays a vital role in hematopoiesis

34
Q

thalassemia

A

group of hereditary anemias characterized by less hemoglobin and fewer RBCs in the body than normal; usually seen in people of Mediterranean origin

35
Q

hemophilia

A

group of hereditary bleeding disorders characterized by a deficiency of one of the factors necessary for coagulation of blood

36
Q

leukemia

A

malignant disease of bone marrow characterized by excessive production of leukocytes

37
Q

acquired immune deficiency syndrome (AIDS)

A

transmissible infection caused by human immunodeficiency virus (HIV) and associated with suppression of the immune system; characterized by increasing susceptibility to infections, malignancies, and neurological diseases

38
Q

immunodeficiency disease

A

any of a group of diseases, either congenital or acquired, caused by a defect in the immune system and generally characterized by susceptibility to infections and chronic diseases

39
Q

Kaposi Sarcoma

A

Malignancy of connective tissue, including bone, fat, muscle, and fibrous tissue, that is commonly fatal (because the tumors readily metastasize to various organs) and closely associated with AIDS; also called malignant neoplasm of soft tissue

40
Q

Lymphadenitis

A

inflammation and enlargement of the lymph nodes, usually as a result of infection, obstruction, or removal of lymph channels

41
Q

lymphedema

A

accumulation of fluid in soft tissue resulting from blockage of lymph that prevents lymph fluid from draining, and the fluid buildup leads to swelling; may be caused by inflammation, obstruction, or removal of lymph channels

42
Q

Lymphoma

A

any malignant tumor of the lymph nodes of other lymph tissue

43
Q

Hodgkin’s Lymphoma

A

malignant disease involving the lymph nodes and the spleen; characterized by the presence of unique Reed-Sternberg cells (malignant) in the lymph nodes

44
Q

non-Hodgkins lymphoma

A

a group of more than 20 different types of lymphomas (except Hodgkin lymphoma) that occur in older adults but are not characterized by Reed-Sternberg cells (malignant cells)

45
Q

mononucleosis

A

acute infection caused by Epstein-Barr virus (EBV) and characterized by a sore throat, fever, fatigue, and enlarged lymph nodes

46
Q

multiple myeloma

A

malignant disease of bone marrow plasma cells (antibody-producing B lymphocytes)

47
Q

opportunistic infection

A

any infection that results from a defective immune system that cannot defend against pathogens normally found in the environment

48
Q

bone marrow aspiration

A

removal of small amount of tissue (bone marrow biopsy) to diagnose blood disorders, cancers, or infectious diseases or to gather cells for later infusion into a patient

49
Q

complete blood count

A

series of blood tests to determine general health status as well as screening for infection, anemias, and other diseases; also called CBC

50
Q

enzyme-linked immunosorbent assay (ELISA)

A

test to screen blood for presence of HIV antibodies or for other disease-causing substances

51
Q

lymphangiography

A

radiographic examination of lymph glands and lymphatic vessels after an injection of a contrast medium to view the path of lymph flow as it moves into the chest region

52
Q

tissue typing

A

technique used to determine the histocompatibility of tissues; used to match donor grafts and transplants with the recipient’s tissues and cells; also known as histocompatibility testing

53
Q

western blot

A

test to detect presence of viral DNA in blood and used to confirm the diagnosis of AIDS as well as for detecting other viruses

54
Q

blood transfusion

A

administration of whole blood or a component, such as packed red blood cells (RBCs), to replace blood lost through trauma, surgery, or disease

55
Q

bone marrow transplant

A

diseased bone marrow is destroyed by irradiation and chemotherapy and replaced from a healthy donor to simulate production of normal blood cells; used treat aplastic anemia, leukemia, and certain cancers

56
Q

lymphangiectomy

A

removal of a lymph vessel

57
Q

anticoagulants

A

prevent or delay blood coagulation

58
Q

immunizations

A

vaccination or injection of immune globulins to induce immunity to a particular infectious disease

59
Q

immunosuppressants

A

suppress the immune response to prevent organ rejection after transplantation to slow the progression of autoimmune disease

60
Q

thrombolytics

A

dissolve a blood clot

61
Q

vaccinations

A

introduction of altered antigens (viruses or bacteria) into the body to produce an immune response and protect against the disease
