in severe intravascular hemolysis DIC can be produced by releasing?

Select the two correct answers
a large amount of III factor
a large amount of ADP
a large amount of RBC membranous phosphatides
a large amount of platelet factors

amniotic fluid embolism may cause a acute DIC because in amniotic fluid there are?

Select the two correct answers
a lot of granule substances
a lot of coagulation inhibitors
a large amount of tissue factor
a lot of microthromb

in acute DIC the effect of the activated fibrinolytic system is?

Select the three correct answers
activate intrinsic pathway of coabulation
degraded microthrombus
inhibiting activity of blood coagualtion
degraded some coagulation factors

what is the decreased reason of coagulation factors in acute DIC?

Select the two correct answers
the blood coagulation factors is consumed severely
the effect of activated secondary fibrinolytic system
the effect of FDP
the effect of hemolytic anemia

the major direct reason of caused shock by an acute DIC are?

Select the three correct answers
the amount of blood return↓ by obstruction of
widespread microthrombosis
the effective blood volume↓ by severe bleeding
the substances of vessel dilation↑ in DIC pathological
process
a great consumed of blood coagulation factors

the hypercoagulable state takes place in?

Select the two correct answers
the impairment of monunclear phagocytes system
the activate stage of fibrinolytic system
the serious alkalosis
the terminal stage of a preganancy

which factors belong to the predisposing factors of DIC?

Select the two correct answers
hypercoagulable state
obstetrc accidents
serious disorder of microcirculation
a large amount of FDP is formed

the impairment of mononuclear phagocytes system is a predisposing factor of DIC, because the impairment of mononuclear phagocytes system may?

Select the two correct answers
make the damage of cascular endothelia severely
promoting production of coagulation factors
decrease clearnce ability of the coagulation initiators
decrease clearance ability of the activating
coagulation factors

in acute DIC the effects of FDP are?

Select the two correct answers
activating fibrinolytic system
promoting hemolytic anemia
promoting microvessel dilation
inhibiting activiting of blood coagulation

which does relate with a bleeding of DIC?

Select the four correct answers
blood coagulation substances consumed
activation of fibrinolytic system
a large amount of FDP is formed
microvascular damages and its permeability increase
by the microthrombus

in an acute DIC the major reason of caused bleeding are?

Select the two correct answers
progressing increase of the coagulation factors
severe lack of vitamin K
microvascular damage severe in DIC pathological
process
production of a great FDP

the common diseases of caused DIC are?

Select the three correct answers
autonimmune disease
obsterc accidents
serious infections
severe trauma
