Anemia
Lower than normal level of hemoglobin; fewer than normal RBC’s. As a result the amount of oxygen delivered to the body tissue is diminished. Not a specific disease state but a sign of underlying cause.
Aplasia
Arrested development
Band Cell
Immature WBC
Dysplasia
Abnormal development (ex: of blood cells)
Eccymosis
Brusing
Erythropoiesis
Process of formation of RBC’s
Erythropoietin
Hormone produced by the kidney necessary for erythropoiesis
Erythrocyte
Red Blood Cells
Fibrin
Filamentous protein; basis of blood clot
Fibronogen
Protein converted into fibrin to form clots
Glossitis
Inflammation of the tounge
Granulocyte
Granulated WBC
Granulocytopenia
Fewer than normal granulocytes
Hematocrit
Percent of total blood volume consisting of RBC’s
Hematopoiesis
Formation and maturation of blood cells
Hemoglobin
Iron containing protein of RBC’s; delivers oxygen to tissues
Hemolysis
Destruction of RBC’s
Hemostasis
Balance between clot formation and clot dissolution
Hyperplasia
Increased proliferation of cells
Left Shift
Increased release of immature WBC’s from the marrow in response to need
Leukocyte
White Blood Cell
Lymphocytes
Form of WBC’s involved in immune functions
Lysis
Destruction of cells
Neutropenia
Lower than normal neutrophils
Neutrophil
Fully mature form of WBC
Pancytopenia
Abnormal decrease in WBC, RBC, and Platelets
Petechaie
Tiny capillary hemorrhages
Plasma
Liquid portion of the blood
Plasminogen
Protein used in dissolution of blood clots
Polycythemia
Excess of red cells
Reticulocyte
Immature RBC
Serum
Portion of blood remaining after coagulation occurs
Stem Cell
Primitive cell, capable of self replication and differentiating into myeloid or lymphoid stem cell
Thrombin
Enzyme necessary to convert fibrinogen into fibrin clot
Thrombocyte
Platelet
Oncology Nursing
Specialty of cancer nursing
Carcinogensis
Process whereby normal cell undergoes malignant transformation, so that cellular DNA is altered
Cancer
The abnormal cell(s) no longer reproduce in orderly fashion at a controlled rate; proliferate abnormally and then begin to be invasive, infiltrating surrounding tissues and/or access blood/lymph system
Dysplasia
Bizarre cell growth—cells differ (size, shape, arrangement) from other cells of same type tissue
Metastases
The abnormal cells proliferate and spread within a body cavity and/or infiltrate lymph and blood vessels to be carried to distant areas
Differentiation
Process by which normal cells undergo changes to perform specialized functions the most malignant and rapid growing neoplasms are undifferentiated or anaplastic with little resemblance to tissue of orign. Benign neoplasms are highly differentiated, tend to be encapsulated and noninvasive/slow growing
Tumor-Specific Antigen
Protein on cancer cell membrane distinguishes the cancer cell from a benign cell (PSA, CEA)
