chapter 29 Flashcards
a calculation of number of circulating neutrophils derived frm the total number of WBC and the percentage of neutrophils counted in a microscope’s visual field
absolute neutrophil count (
decreased RBC count
anemia
lack of cellular development (of cells within the bone marrow)
aplasia
iron-containing pigment derived from breakdown of hemoglobin
hemosiderin
uncontolled proliferation of WBCs
leukemia
pallor within RBCs caused by decreased hemoglobin content
hypochromia
a type of anemia characterized by abnormally larged nucleated RBCs
megaloblastic anemia
smaller than normal rbc
microcytosis
normal RBC color indicating normal amount of hgb
normochromic
normal size of RBC
normocytic
abnormal decreased in RBC, WBC, and platelets
pancytopenia
tiny cappillary hemorrhages
petechiae
variation of shape in rbcs
poikilocytosis
excess RBC is called
polycythemia
small, spherically shaped rbcs
spherocytes
lower than normal platelet count
thrombocytopenia
higher than normal platelet count
thrombocytopenia
destruction of rbc with release of cellular components into the circulation; may occur within or outside the vasculature
hemolysis
- type of anemia occur when the bone marrow produces inadequate number of erythrocytes
- causes include bone marrow damage from chemicals, medications, lack of important factors that promote erythrocyte production, and lack of nutrients
hypoproliferative anemia
a type of anemia where premature destruction of erythrocytes results in the liberation of hgb from the erythrocytes to the plasma
hemolytic anemia
complications of anemia
HF, paresthesias, delirium
jaundice, angular cheilitis, brittle and concave, ridged nails, beefy and red tongue may be associated with
megaloblastic anemia
smooth and red tongue, experiences pica, a craving for ice, starch, dirt and resttless leg syndrome may be seen with
iron deficiency anemia
people who follow strict vegetarian diet and do not supplement with vit B12 are at risk for
megalobastic anemia
