Hematology: Blood (Pt. 2) Flashcards
(33 cards)
Clot
Hard collection of fibrin, blood cells, and tissue debris that is end result of hemostasis or blood-clotting process.
Anemia
Group of blood disorders involving either a reduction in number of circulating erythrocytes or amount of hemoglobin in red blood cells; results in decreased oxygen delivery to tissues.
Anticoagulant
Any substance that prevents clot formation
Aplastic Anemia
Severe form of anemia caused by loss of functioning red bone marrow; results in decrease in number of all blood cells; may require bone marrow transplant.
Autotransfusion
Collecting and storing one’s own blood to use to replace blood lost during surgery.
Blood Culture and Sensitivity (C&S)
Blood specimen incubated to check for bacterial growth; if bacteria is present, they are identified and best antibiotic treatment is determined.
Blood Transfusion
Transfer of blood from one person to another; there four types of blood: A, B, AB, O.
Bone Marrow Aspiration
Removal of small sample of bone marrow by needle and examined for diseases such as leukemia or aplastic anemia.
Bone Marrow Transplant (BMT)
Patient receives red bone marrow donation after own bone marrow is destroyed by radiation or chemotherapy.
Coagulate
Formation of blood clot
Complete Blood Count (CBC)
Comprehensive blood test that includes red blood cell count (RBC), white blood cell count (WBC), hemoglobin (Hgb), hematocrit (Hct), white blood cell differential, and platelet count.
Embolus
Commonly called floating clot; usually piece of thrombus breaks away and floats through bloodstream until it lodges in a smaller blood vessel and blocks blood flow.
Erythrocyte Sedimentation Rate (ESR, sed rate)
Blood test that measures rate at which red blood cells settle out of blood to form sediment in bottom of test tube; indicates presence of inflammatory disease.
Hematocrit (HCT, Hct, crit)
Blood test that measures volume of red blood cells within total colume of blood.
Hematoma
Blood collection under skin by escaping into tissue from damaged blood vessel; commonly called bruise.
Hemoglobin (Hgb, hb)
Blood test that measures amount of hemoglobin present in given volume of blood.
Hemophilia
Inherited lack of a vital clotting factor; results in almost complete inability to stop bleeding.
Iron-deficiency Anemia
Anemia resulting when there is not enough iron to build hemoglobin for red blood cells.
Leukemia
Cancer of leukocyte-forming red bone marrow; patient has large number of abnormal and immature leukocytes circulating in blood
Pernicious Anemia (PA)
Anemia resulting when digestive system absorbs insufficient amount of vitamin B12; vitamin B12 is necessary for erythrocyte production.
Phlebotomy
Removal of blood specimen from vein for laboratory tests; also called venipuncture.
Platelet Count
Blood test that determines the amount of platelets in given volume of blood.
Polycythemia Vera
Condition characterized by too many erythrocytes; blood becomes too thick to flow easily through blood vessels.
Prothrombin Time (Pro Time, PT)
Blood test that measures how long it takes for clot to form after prothrombin, a blood clotting protein, is activated.
