In the progressive stage of shock, the microcirculation was mainly presented A: microcirculation ischemia B: microcirculation Congestion C: microcirculation Blood coagulation D: microcirculation Failure

Which indicator can be mainly reflected by the level of systolic blood pressure in general? A: Cardiac stroke volume B: Heart rate C: Peripheral resistance D: Capillary pressure in the microcirculation

The "autoinfusion" at the early stage of shock is due to A: constriction of capacity vessels B: increased return of tissue fluid C: constriction of blood storage organs such as liver and spleen D: increased capillary hydrostatic pressure E: microcirculation congestion

Which is correct to explain the fluid exudation? A: The intravascular fluid accumulation is termed as edema B: Exudate has two patterns, edema and transudate C: Exudate contains more blood cells, and high protein content D: Exudate is formed in the microcirculation with normal vascular permeability

5. The characteristics of microcirculation in late shock stage are: A: A. Increased forward resistance and significantly decreased perfusion and slower blood flow through the capillary network. B: B. Increased rear resistance and significantly increased perfusion and slower blood flow through the capillary network. C: C. The microvessels are paralytically dilated, no perfusion and blood flow through the capillary network. D: D. Continuous spasm and contraction of microcirculation.
