Chapter 41 and 42 Hematology Flashcards
Fibrinolytics
Selectively degrade fibrin threads in the formed blood clot
Platelet Inhibitors
prevent platelets from becoming active or activated platelets from clumping together
Anemia
Reduction in RBC’s, hemoglobin, or hematocrit
Sickle cell disease
Genetic
chronic anemia, pain, disability, organ damage, increased risk for infection, and early death
Sickle Cell Disease: Pathophysiology
Formation of abnormal hemoglobin chains
Iron Deficiency Anemia cause
blood loss, poor intestinal absorption, or inadequate diet
Iron Deficiency Anemia sx
weakness and pallor
abnormal bleeding, especially from the GI tract
Causes of Vitamin B12 Deficiency Anemia
small bowel resection, tapeworm, overgrowth of intestinal bacteria
Result of Vitamin B12 Deficiency Anemia
improper DNA synthesis of RBCs.
Pernicious Anemia
failure to absorb vitamin B12
Caused by a deficiency of intrinsic factor
Aplastic Anemia
Deficiency of circulating RBCs
failure of the bone marrow to produce RBC’s
Aplastic Anemia tx
Blood transfusions
Immunosuppressive therapy
Splenectomy
Polycythemia Vera
Cancer of the RBCs
Increase in blood hemoglobin or hematocrit
Over production of red blood cells, leukocytes and platelets
Polycythemia Vera tx
Phlebotomy
Hydration
Anticoagulants
Myelodysplastic Syndromes
caused by the formation of abnormal cells in the bone marrow
Drugs for iron overload
deferasirox and deferoxamine mesylate
Leukemia
of cancer with uncontrolled production of immature white blood cells in the bone marrow
Laboratory assessment of leukemia
Decreased H&H
Low platelets
Abnormal WBC (high)
Hodgkin’s Lymphoma: Interventions
One of the most treatable types of cancer
External radiation
Chemotherapy
Hodgkin’s Lymphoma marker
Reed-Sternberg cell
Spreads to different lymph nodes in an orderly fashion
Hodgkin’s Lymphoma sx
Large, painless lymph node, usually in the neck, becomes painful when alcohol ingested; fever, drenching night sweats, and unexplained weight loss
Non-Hodgkin’s Lymphoma
more than 12 types
do not have Reed-Sternberg cell
Not orderly
