Which condition is described as a syndrome of signs and symptoms due to inadequate tissue perfusion with oxygen?

• A. Shock
• B. Hypertension
• C. Anemia
• D. Dehydration

Answer: (A)

Shock is a state in which tissues do not receive enough blood flow to supply oxygen, so cells can’t adequately meet their energy needs. This pattern of inadequate perfusion creates a recognizable set of signs and symptoms—the body's overall response to insufficient oxygen delivery at the tissue level. That makes the description fit shock best, since it’s defined by the systemic signs that arise from hypoperfusion and cellular hypoxia. Hypertension is simply high blood pressure, not a syndrome of hypoperfusion. Anemia lowers the blood’s capacity to carry oxygen but doesn’t by itself define a perfusion failure. Dehydration reduces blood volume and can contribute to insufficient perfusion if severe, but the phrase describing a syndrome of signs and symptoms due to inadequate tissue oxygen delivery aligns with shock as the overall condition.
