what is myeloid leukemia?
uncontrolled granulocyte production
what is lymphocytic leukemia?
involves lymphocytes (B and T cells)
what is Acute Myeloid Leukemia?
rapid proliferation of myeloblasts
what is the patho of Acute Myeloid Leukemia?
hyperplasia in bone marrow
what are the clinical mani of Acute Myeloid Leukemia?
P, IOLC, OI, AB
pancytopenia (caused by immature myeloblasts replacing cells and hemopoietic cells)
leukemic cells infiltrate other organs
opportunistic infections
abnormal bleeding
what is the name of an immature RBC?
reticulocyte?
what is an expected finding of increased PT or PTT
signs of inccreased bleeding
jaundice is a clinical mani of which type of anemia?
sickle cell anemia
what is a characteristic of an erthrocyte associated with pernicous anemia?
megoblastic
in which anemia’s are RBC’s destroyed?
T, SCA
Thalassemia and sickle cell anemia
aplastic anemia differs from other anemia because of what characteristic?
complete lack of bone marrow function causing a decrease in all BC
what is the main characteristic of DIC (disseminated intravascular coagulation)?
excessive bleedingh and clotting at the same time
what is the etiology of hemophilia?
inherited genetic disorder
what is aplastic anemia?
when your bone marrow cannot make enough new blood cells for your body to work normally
what is thalassemia anemia?
Thalassemia is an inherited blood disorder characterized by less oxygen-carrying protein (hemoglobin) and fewer red blood cells in the body than normal.
what is Prothrombin Time (PT)?
test is a test to evaluate blood clotting
what is a Partial thromboplastin time (PTT)?
a blood test that looks at how long it takes for blood to clot. It can help tell if you have a bleeding problem
what is polycethemia?
a type of blood cancer. It causes your bone marrow to make too many red blood cells.
