Select the stage of shock that is accurately paired with its characteristic:
A- The initial stage of shock: Hyperventilation occurs and the blood pH rises.
B- The compensatory stage of shock: Hypoxia occurs and lactic acid rises.
C- The progressive stage of shock: Histamine is released; fluid and proteins leak into surrounding tissues and the blood thickens.
D- The refractory stage of shock: Potassium ions leak out, sodium ions build up and metabolic acidosis increases.
Correct Response: C
During the progressive stage of shock, histamine is released, fluid and proteins leak into surrounding tissues and the blood thickens. The initial stage of shock is marked with hypoxia and an increase in lactic acid; the compensatory stage of shock is characterized with hyperventilation and rises in the blood pH. The progressive stage of shock is also characterized with the leakage of potassium ions, the buildup of sodium ions and increasingly more severe metabolic acidosis. The refractory, or final, stage of shock becomes irreversible.
