alteration in hematologic function Flashcards
primary result of Anemia
tissue hypoxia
hypoxemia
decreased O2 in the blood
what causes anemia
altered production of RBC
blood loss
increased destruction of RBCs
normocytic
red blood cells a normla size
macrocytic
abnormall large cell
microcytic
abnormally small cell
normochromic
normal RBC
hypochromic
not enough hemoglobin in RBC
hyperchromic
too much hemoglobin in RBC
anisocytosis
red blood cells being made in a variety of sizes
poikilocytosis
red blood cells made in a variety of shapes
pernicious anemia
macrocytic normochromic
don’t produce enough intrinsic factor, which means not enough B12
folate deficiency anemia
macrocytic-normochromic
not enough folic acid
Iron deficiency anemia
microcytic-hypochromic anemia
sideroblastic anemia
microcytic-hypochromic
iron not being properly used for hemoglobin, causes precursors with rings
The thalassemias
microcytic-hypochromic
effect 2 alpha and 2 beta particles that make up hemoglobin
insufficient oxygen in blood supply
aplastic anemia
normocytic-normochromic
malignancy of some kind, not making enough RBCs
hemolytic anemia
normocytic-normochromic
red blood cells bursting, cannot maintain red blood cell intergtrity
hemolytic disease of the newborn
aquired
Rh factor (mom negative, baby positive)
sickle cell anemia
hereditary hemolytic anemia
psthemorrhagic anemia
after blood loss, while hypovolemic
anemia of chronic inflammation
inflammation can impede bodies ability to form red blood cells
polycythemia
too mnay red blood cells, blood gets sticky and does not circulate well
relative polycythemia
just appears to be too thick, but may be temproary like with dehydration
absolute polycythemia
too many red blood cells
secondary absolut polycythemia
body compensates for having less oxygen by producing more RBCs, like with high altitudes
polycythemia vera
thick stick blood, often for JAK2 mutation
increased risk for ischemia/infartion of tissue
iron overload
too much iron, treated with chelation therapy
hereditary hemochomatosis
iron does not get processed correctly, blood need to be removed
lymphadenopathy
some disease that affects the lymph nodes
hodgkins lymphoma
had reed-strenberg cells, cells with gigantic nucelus
has better prognosis
non-hodgkin lymphoma
involves T,B, NK cells
burkitts lymphoma
a complication of mono
multiple myeloma
malignancy of plasma cells
splenomegaly
enlarge spleen, like with ifectious diseases (mono)
hypersplenism
hyperactive spleen, causes decrease in amount of RBCs and WBC and platelets ciculating
thrombocyopenia
deficieency in platelets
thrombocythemia
excess of platelets
primary thrombocythemia
from a malignant condition
secondary thrombocythemia
relative, and lieka spike in platelets when spleen is removed
impaired hemostasis
problem forming blood clots because of problem with platelets
hemophilia
problem with clotting cascade, a protein that forms blood clots is missing
immune thrombocytopenic purpura
antibodies against own platelets
what can platelet disorders cause
vasculitis (inflammation of blood vessels) or erythromelalgia
disseminated intravascular coagulation
abnormal blood clotting throughout the body
thrombus
a blood clot attached to a vessel wall
ambolus
air, flat, or blood clot that block blood flow
hypercoagulability
blood clots too easily
triad of virchow
injury to blood vessel endothelium
abnormalities in blood flow
hypercoagulability
what often causes DVT
immobility
