Explanation
A. Circulating blood volume is decreased – This is true specifically in hypovolemic shock, but it does not apply to all types of shock (e.g., septic or cardiogenic shock).
B. Cells lack an adequate blood supply and are deprived of oxygen and nutrients – This is the most accurate and comprehensive description of the pathophysiology of shock. Shock is defined as a state of cellular and tissue hypoperfusion, regardless of the underlying cause.
C. Hemorrhage occurs as a result of trauma – While hemorrhage can cause hypovolemic shock, it is not the universal cause of all types of shock.
D. Blood is shunted from vital organs to peripheral areas of the body – The opposite is true in shock: blood is typically shunted away from peripheral tissues to preserve perfusion to vital organs like the brain and heart.
