NURS 3444 Quiz: Hematology
Document Summary
Blood: plasma: protein, erythrocytes, matrix, albumin, electrolytes, antibodies, fibrinogen, globulins, formed solutes: rbcs, wbcs, platelets (90% cellular, = fluid + cellular. Hematopoiesis: stem cell erythroblast, wbc reticulocyte: early rbc, myeloblast baso, eosino, neutrophils (immediate shock troops, lymphoblast lymphocyte, monoblast monocyte. Jaundice, kernicterus (irreparable brain damage: bilirubin is by-product of rbc destruction resulting from breakdown of hgb in rbcs, trauma, swelling on head, abo incompatibility, safe zone: amount of bilirubin and age in hrs. Anemia: decreased rbc production, nutritional deficiency, bone marrow failure. Intracorpuscular or extracorpuscular: decrease in number of rbcs and/or hemoglobin concentration below normal - oxygen- carrying capacity of blood. Anemias: microcytic, small and pale, defect in hgb synthesis. Iron deficiency anemia: lead poisoning, normocytic, normal size and normochromatic. Increased destruction or decreased production of rbcs: chronic hemolytic anemias (sca, thalassemia trait), infections parvovirus, b19, Hiv, sepsis, leukemia, hemolytic uremic syndrome, autoimmune hemolytic anemia like glucose 6 phosphate dehydrogenase: macrocytic, large, vitamin b12 and folate deficiencies, hypothyroidism.
