Hypovolemic Anemia Anemia due to hemorrhage. S/SX=weakness,stupor,pale,cool,moist. STOP BLEEDING
Pernicious Anemia Autoimmune disorder resulting from destruction of parietal cells and eventual gastric mucosa atrophy.Decreased intrinsic factor=less B12 absorption
Aplastic Anemia failure of normal process of generation and growth. Usually pancytopenic
Iron deficiency Anemia RBCs contain decreased levels of hemoglobin. Pallor-Glossitis-S/Sx similar to that of angina/HF
Sickle Cell Anemia abn crescent RBC contain Hg-S instead of Hg-A. Most common genetic disorder.
Sickle Cell(S/Sx) abd enlargement due to blood pooling in organs-joint/back pain-extremety edema-multisystem failure
Polycythemia Vera myeloproliferative disorder with hyperplasia of bone marrow causing increased circulating erythrocytes,granulocytes, and platelets(overproduction of blood)
Secondary Polycythemia Hypoxia stimulates erythropoietein in kidneys which stimulates erythrocyte production
Clinical Manifest. of Polycythemia Gradual onset-middle aged men-venous distention-epistaxis-petechiae-hepato/splenomegaly
Blood products accepted by Jehovah's Witnesses autologous and volume expanders
Agranulocytosis severe reduction in number of granulocytes(phils)
Agranulocytosis Manifestation fever-chills-headache-fatigue-ulcerations-bronchial pneumonia-UTIs
Leukemia malignant disorder of hematopoietic system in which an excess of leukocytes accumulates in the bone marrow and lymph nodes
Leukemia Manifestations Anemia-thrombocytopenia(petechiae,epistaxis)-leukopenia-enlarged lymph nodes-painless splenomegaly
Multiple Myeloma malignant neoplastic immunodeficiency disease of the bone marrow-Pt susceptible to infection
Types of Leukemia ALL(acute lymphocytic leukemia)-AML(acute mylogenous leukemia)-Chronic lymphocytic leukemia(CLL)
Four Steps of Hemostasis 1)vessel spasm-contraction after damage 2)platelet plug-platelets activated 3)clotting cascade-prothrombin converted to thrombin. Thrombin degrades to fibrin. 4)fibrinolysis-t-PA released. Plasmin dissolves clot
Coagulopathies component necessary to control bleeding is missing--thrombocytopenia,hemophilia,DIC
Thrombocytopenia deficiency in number of platelets--melena-hematuria-petechiae-ecchymosis-epistaxis
Hemophilia x linked hereditary trait. decrease in formation of prothrombin. deformed muscles-immoblie joints(anklosed)-hemarthrosis-pain
DIC Overstimulation of clotting/anticlotting processes. bleeding complaints-dyspnea-bone/joint pain-visual changes-occult blood-petechiae-abd tenderness
Von Willibrand's Disease inherited bleeding disorder characterized by abnormally slow coagulation of blood and spontaneous episodes of GI bleeding,epistaxis, and gingival bleeding caused by mild deficiency of factor VIII
Lymphangitis inflammation of lymphatic vessels of channels caused by infection in extremity. Swollen lymph nodes-fine red streaks-septicemia
Lymphedema accumulation of lymph in soft tissue and edema. Pressure in extremeties due to edema-pain
