Hematology assess 5

SOPN Hematology assess 5

QuestionAnswer
The process of red bone marrow producing red blood cells hemapoiesis
all types of blood cells originate from what type of immature cell found in the marrow? STEM CELL
a hormone secreted by the kidneys which helps to stimulate RBC production ERYTHROPOIETIN
Medication that stimulates RBC production. Acts just like erythropoietin EPOGEN $$$ PROCRIT
What two things make up hemoglobin (HgB)? HEME - GLOBIN
What is an immature RBC reticulocyte
Destruction of RBC's, results in increased bilirubin HEMOLYSIS
If the body were destroying alot of RBC's then you will see an increase in what? reticulocytes
Excess of bilirubin in excess of what can be excreted by the liver would lead to what condition? Jaundice
the process of digesting unwanted organisms phagocytosis
name the granulocytes? GREAT NEW EASY BAKE oven! Neutrophils - eosinophils - basophils
WBC'S are leukocytes made up of what 3 things? --- TAG ! you're it! --- granulocytes - used for phagocytosisagranulocytes - immune responsethrombocytes - clotting process
Involved in the immune response and include B-cells and T-cells lymphocytes
what 2 things performs phagocytosis and facilitates immune response granulocytes - monocytes
another name for platelets that initiate the clotting process thrombocytes
What organ would "phagocytize" old RBC's (ingest and destroy) - Also resuses iron by sending it to the marrow for re-use - also used for storage for RBCs and platelets spleen
where would iron be recycled? macrophages
carries fluid form interstitial spaces to and from blood. PREVENTS EDEMA drains into the subclavian vein Lymph system
clumps of tissue whos primary function is filtration of pathogens and removal of forgein particles Lymph nodes
Acts as a filter - produces several clotting factors - stores Iron Liver
What test assesses all 3 types of blood cells formed in the marrow? WBC - RBC - platelets CBC - complete blood count
What condition occurs when all 3 major types of blood cells are DEPRESSED (low counts WBC - RBC - platelets) pancytopenia
What test measures the gas carrying capacity of the RBC HgB
what test tests the volume of RBC's as a percentage of total blood volume HcT
abnormally small RBC's microcytosis (low MCV)
abnormally large RBC's macrocytosis (high MCV)
amount saturation HgB in RBC's MCHC
low MCH or high MCH is the weight of the RBC's
shape and appearance of RBC's RBC MORPHOLOGY
leukocytosis count over 11,000/ul associated with infection, inflammation, tissue injury/death, or malignancies
leukopenia count less than 4,000/ul associated with bone marrow depression
measures the percentage of each type of leukocyte WBC differential count
The actual WBC count is normal BUT there is an increase in neutrophils indicating infection (bacterial)
Normal platelet count 150,000 - 400,000/ul
platelet count of over 400,000/ul means what? Thrombocytosis and may indicate excessive clotting
platelet count of less than 150,000/ul indicates what? thrombocytopenia and may cause bleeding
measures the settling rate of RBC's (which increases often in the inflammatory processes where there is increased destruction of RBC's) ESR = erythrocyte sedimentation rate
RBC contains "A" antigens blood type A
RBC contains "B" antigens blood type B
RBC contains both "A" and "B" antigens blood type AB
RBC contains * NO * antigens blood type O
RBC has "D" antigen Rh positive
RBC does not have the "D" antigen Rh negative
measures protein bound iron circulating in serum serum iron
measures amount of protein available that carry the iron from tissues to bone marrow which include the amount of transferrin present TIBC = total iron bindinf capacity
an iron storage protein directly relates to amount of iron body stores ferritin levels
what test can be used to evaluate lymph nodes, liver, or spleen? CT or MRI Scans
what test is used to detect malignancies? Indicate increased activity which may be typical in tumors/malignancies. Tracer highlights "HOTSPOTS" PET SCAN (positron emission tomography)
Preferred site for a bone marrow biopsies Posterior Iliac Crest
lymph node biopsy done via a small needle aspiration, direct pressure applied after procedure Closed Biopsy
lymph node biopsy where an actual incision is made, lymph node is excised, local or general anthesia is used Open Biopsy
