Chapter 6 Pathology, Diagnostic, Therapeutic, Pharmacology Flashcards
dyscrasia
presence of disease affecting blood
hematoma
blood under skin - blood escapes into tissue from damaged vessels - bruise
thrombus
hard collection of fibrin, BC, tissue debris - end of hemostasis - stops bleeding - hurtful if in blood vessel - blood clot
hemophilia
hereditary - clotting prolonged - sex linked from fem to male - almost all in male
septicemia
bacteria or toxins in bloodstream - sepsis - blood poisoning
anemia
group of conditions - penia of RBC or hemoglobin - less oxygen to tissues
aplastic anemia
severe anemia - red bone marrow not functioning - penia of all formed elements - bone marrow transplant
hemolytic reaction
destruction of RBC - when retrieving incompatible blood transfusion
hypochromic anemia
penia of hemoglobin
pernicious anemia
insufficient absorption vit b12 by digestive system - b12 essential in RBC production
polycythemia vera
too many blood cells produced by bone marrow
thalassemia
unable to produce functioning hemoglobin - results in anemia
leukemia
cancer in red bone marrow - abnormal & immature leukocytes
lymphocytic leukemia
leukemia - abnormal WBC are lymphocytes
myeloid leukemia
leukemia - abnormal leukocytes are granulocytes
erythrocyte sedimentation rate
test for rate for mature RBC to settle after addition of anticoagulant
hematocrit
test measures volume of RBC in total volume of blood
prothrombin time
blood’s coagulation abilities
red blood cell morphology
detects diseases such as sickle cell anemia
white blood cell differential
determines number of each leukocyte
bone marrow aspiration
removal with needle - bone marrow sample - for leukemia or aplastic anemia
autologous transfusion
collection of patient blood weeks prior to need
packed red cells
transfusion where only erythrocytes are present
additive
sum of action of two or more drugs
contraindication
when a particular drug shouldn’t be used
potentiation
giving second drug to boost effect of first drug
antiplatelet agents
prolongs bleeding time - prevent heart attacks and strokes
fibrinolytics
dissolve blood clots
hematinic
increase RBC or hemoglobin in blood
hives
wheals from allergic reaction
urticaria
itching associated with hives - food allergy, stress, drug reaction
elephantiasis
inflammation, obstruction, destruction of lymph vessels in tissues from edema
hodgkin’s disease
cancer of lymphatic cells - concentrated in lymph nodes
acquired immunodeficiency syndrome
defect in cell mediated immunity - infections in late stage HIV - attacks T4 lymphocytes
AIDS related complex
early AIDS - mild symptoms - weight loss, fatigue, skin rash, anorexia
graft versus host disease
complication in bone marrow transplant - donor cells attack host tissues
kaposi’s sarcoma
skin cancer frequent in AIDS patients - brownish purple papules - metastasize to internal organs
multiple myeloma
in plasma cells - collect in bone marrow - bone marrow tumor may spread to skeleton
pneumocystis pneumonia
pneumonia - weakened immune system such as AIDS patients - pneumocystis jiroveci fungus
sarcoidosis
autoimmune disease - fibrous legions in lymph nodes, liver, skin, lungs, spleen, eyes, small bones of hands and feet
severe combined immunodeficiency syndrome
disease in children with nonfunctioning immune system - forced live in sterile rooms
carbapenem resistant enterobacteriacea
infection by bacteria with resistance to antibiotics called carbapenems - almost all occur in healthcare settings
clostridium difficile infection
inflammation of colon - diarrhea, nausea, fever, abdominal pain
methicillin resistant staphylococcus aureus infection
bacteria resistant to common antibiotics - spread through contain of contaminated surface
antinuclear antibody test
test to diagnose autoimmune disease
lymphangiography
x-ray of lymph vessels - injection of dye in foot
monospot
test for infectious mononucleosis
corticosteroids
adrenal cortex hormone - strong anti inflammatory properties - treatment autoimmune disease
protease inhibitor drugs
inhibit protease enzyme that viruses need
reverse transcriptase inhibitor drugs
inhibit reverse transcriptase enzyme needed by viruses
