What is shock?
I- It is an acute and systemic hemodynamic disorder characterized by the inability of the circulatory system to maintain arterial pressure at a sufficient level to ensure the blood perfusion of vital organs, resulting in generalized hypoxia.
II- It is a circulatory failure associated with a severe disorder of microcirculation and generalized hypoperfusion of organs and tissues.
III- It is a type of shock that occurs due to neurogenic deregulation.
IV- It is a type of shock that occurs due to a sudden restriction in the filling of the left cardiac chambers.
a) Only I and II are correct.
b) Only II and III are correct.
c) Only I, II, and IV are correct.
d) Only II, III, and IV are correct.

A resposta correta é a alternativa "a) Apenas I e II estão corretas". O choque é uma falha circulatória que pode ser causada por diversos fatores, como perda de sangue, infecções graves, reações alérgicas, entre outros. As opções II e III estão incorretas, pois o choque não é necessariamente associado a uma desordem da microcirculação ou a uma deregulação neurogênica. A opção IV também está incorreta, pois o choque não é causado por uma restrição súbita no enchimento das câmaras cardíacas esquerdas.
