What term describes circulatory insufficiency causing tissue hypoperfusion, metabolic acidosis, and decreased venous oxygen content?

• A. Shock
• B. Sepsis
• C. Hypovolemia
• D. Cardiogenic

Answer: (A)

Shock is a state of circulatory insufficiency causing tissue hypoperfusion and inadequate oxygen delivery, which drives anaerobic metabolism and metabolic acidosis. When delivery falls short, tissues extract more oxygen, so venous oxygen content decreases. This pattern reflects a systemic perfusion problem, with specific etiologies like hypovolemia or cardiogenic failure possible; sepsis is a common cause of distributive shock, but the overarching term for this constellation is shock.
