Chapter 6: Blood Flashcards
Pathology: condition of having too few white blood cells
leukopenia
Pathology: condition of having too few platelets
thrombocytopenia
Pathology: condition of having too high a level of lipids such as cholesterol in bloodstream; risk factor for developing atherosclerosis and coronary artery disease
hyperlipidemia
Pathology: general term for indicating presence of a disease affecting blood
dyscrasia
Pathology: condition of having too many white blood cells
leukocytosis
Pathology: genetic disorder in which erythrocytes take on abnormal curved or sickle shape; cells are fragile and are easily damaged, leading to hemolytic anemia
sickle cell anemia
Diagnostic Procedure: incision into vein to remove blood for diagnostic test; venipuncture
phlebotomy
Pathology: blood flowing out of blood vessel; bleeding
hemorrhage
Diagnostic Procedure: determines number of platelets in given volume of blood
platelet count
Therapeutic Procedure: procedure for collecting and storing patient’s own blood several weeks to prior to actual need; can be used to replace blood lost during surgical procedure
autologous transfusion
Pharmacology: given patient a second drug to boost effect of another drug; total strength of drugs is greater than sum of strength of individual drugs
potentiation
Pathology: anemia resulting from having insufficient hemoglobin in erythrocytes; named because hemoglobin molecule is responsible for dark red color of erythrocytes
hypochromic anemia
Pathology: hard collection of fibrin, blood cells, and tissue debris that is end result of hemostasis or blood-clotting process; blood clot
thrombus
Diagnostic Procedure: determines number of each variety of leukocytes in volume of blood
white blood cell differential (diff)
Drugs: increases number of erythrocytes or amount of hemoglobin in blood (ex. epoetin alfa, Procrit; darbepoetin alfa, Aranesp)
hematinic
Pathology: branch of medicine specializing in treatment of diseases and conditions of blood
hematology
Pathology: anemia that develops as result of destruction of erythrocytes
hemolytic anemia
Therapeutic Procedure: replacement of blood by transfusion of blood received from another person
homologous transfustion
Diagnostic Procedure: determines disease such as sickle cell anemia through examination of specimen of blood for abnormalities in shape of erythrocytes
red blood cell morphology
Pathology: cancer located in red bone marrow tissue responsible for producing white blood cells; results in large number of abnormal and immature leukocytes circulating in bloodstream
leukemia
Pathology: severe form of anemia that develops as a consequence of loss of functioning red bone marrow; results in decrease in number of all formed elements; may eventually require bone marrow transplant
aplastic anemia
Diagnostic Procedure: indicates blood’s coagulation abilities by measuring how long it takes for a clot to form after prothrombin has been activated
prothrombin time (pro-time, PT)
Pathology: large group of conditions characterized by reduction in number of red blood cells or amount of hemoglobin in blood; results in less oxygen reaching tissues
anemia
Diagnostic Procedure: blood test to measure volume of red blood cells (erythrocytes) within total volume of blood
hematocrit (HCT, Hct, crit)
Pharmacology: sum of action of two or more drugs given; total strength of medications is equal to sum of strength of each individual drug
additive
Diagnostic Procedure: measures number of leukocytes in blood
white blood cell count (WBC)
Diagnostic Procedure: removed by aspiration with a need, sample of bone marrow is examined for diseases
bone marrow aspiration
Pathology: having too few of all cells
pancytopenia
Pathology: genetic disorder in which body is unable to make functioning hemoglobin, resulting in anemia
thalassemia
Drugs: able to dissolve existing blood clots (ex. alteplase, Activase,tissue plasminogen activator; Tenecteplase)
fibrinolytic
Diagnostic Procedure: blood test to determine rate mature blood cells settle out of blood after addition of anticoagulant; indicated presence of inflammatory disease
erythrocytes sedimentation rate
