blood 5; disorders of hemostasis Flashcards
vitamin k deficiency disorders include
liver disease
malabsorption syndromes
prothrombin turns into
thrombin
bruising for seemingly no reason
purpura
carries coagulation factor 8
von willebrand factor
stoppage of blood flow
hemostasis
thrombotic thrombocytopenic purpura
bacteria activates thrombosis; runs out of platelets and bleeds under skin (bruise)
plasmapheresis required
potentially fatal
white blood cells that live in tissue lifespan
3-5 days
bruising on bottoms of feet while crawling/walking
hemophilia
treatment is used so patient doesnt bleed out during surgery
prophylaxis
needed to form platelet plug
von willebrand factor
fibrinogen turns into
fibrin
average thrombocyte lifespan
8-9 days
antigen/antibody complex that causes platelet destruction
drug induced thrombocytopenia
angiogenesis
beginning of new vessels
happens immediately after injury
TTP =
thrombotic thrombocytopenic purpura
hypercoagulability can come from
increased platelet function
increase clotting factor activity
increased platelets and clotting factor
hypercoagulability
in blood coag, __ is required
vitamin K
fibrinolysis
destroys blood clots
x linked; coag defected
hemophilia
clot retraction/ drying out
clot restraction
intentional removal of blood by needle treatment
plasmapheresis
thrombocyte range
150K to 400K
serum is extracted in this stage of hemostasis
clot retraction/ drying out
stages of hemostasis
vessel spasm forms platelet plug blood coagulation clot retraction clot dissolution
prophylaxis
treatment is used so patient doesnt bleed out during surgery
DIC=
disseminated intravascular coagulation
less than 100K platelets
thrombocytopenia
vitamin K is known to help the
liver
hemophilia
von willebrand disease
vitamin k deficency disorders
coag defects
thrombopoietin is an example of
colony stimulating factor
disseminated intravascular coagulation
overclotting when major bleeding occurs, uses all platelets and later bleeds to death
purpura
bruising for seemingly no reason
