Flashcards in Chapter 31 Nursing Management: Hematologic Problems VOCAB Deck (20):
1

Anemia

a deficiency in the number of erythrocytes (red blood cells [RBCs]), the quantity or quality of hemoglobin, and/or the volume of packed RBCs (hematocrit)

2

Aplastic anemia

a heterogeneous group of malignant neoplasms of primarily B-, T-, or natural killer (NK) cell origin affecting all ages

3

Disseminated Intravascular Coagulation (DIC)

a grave coagulopathy resulting from the overstimulation of clotting and anticlotting processes in response to disease or injury.

4

Hemochromatosis

an autosomal recessive disease characterized by increased intestinal iron absorption and, as a result, increased tissue iron deposition.

5

Hemolytic anemia

an anemia caused by destruction of RBCs at a rate that exceeds production.

6

Hemophilia

hereditary bleeding disorders caused by defective or deficient clotting factors.

7

Hodgkin's lymphoma

a malignant condition characterized by proliferation of abnormal giant, multinucleated cells, called Reed-Sternberg cells, which are located in lymph nodes.

8

Iron-deficiency anemia

a microcytic hypochromic anemia caused by inadequate supplies of iron needed to synthesize hemoglobin; characterized by pallor, fatigue, and weakness.

9

Leukemia

a broad term given to a group of malignant diseases characterized by diffuse replacement of bone marrow with proliferating leukocyte precursors.

10

Lymphomas

malignant neoplasms originating in the bone marrow and lymphatic structures resulting in the proliferation of lymphocytes.

11

Megaloblastic anemias

a group of disorders caused by impaired DNA synthesis and characterized by the presence of large red blood cells.

12

Multiple myeloma

a condition in which malignant neoplastic plasma cells infiltrate the bone marrow and destroy bone.

13

Myelodysplastic syndrome (MDS)

a group of related hematologic disorders characterized by a change in the quantity and quality of bone marrow elements.

14

Neutropenia

an abnormal reduction of the neutrophil count to <1000/µL.

15

non-Hodgkin's lymphomas (NHLs)

a heterogeneous group of malignant neoplasms of primarily B-, T-, or natural killer (NK) cell origin affecting all ages

16

Pernicious anemia

a progressive megaloblastic macrocytic anemia resulting from inadequate gastric secretion of intrinsic factor necessary for absorption of cobalamin.

17

Polycythemia

an abnormal condition with excessive levels of red blood cells.

18

Sickle cell disease (SCD)

a group of inherited, autosomal recessive disorders characterized by the presence of an abnormal form of hemoglobin in the erythrocyte.

19

Thalassemia

an autosomal recessive genetic disorder of inadequate production of normal hemoglobin.

20

Thrombocytopenia

a reduction of the platelet count.
