Which statement best defines shock?

• A. A chronic condition causing gradual fatigue.
• B. A temporary condition of dizziness.
• C. Sudden physical or mental collapse or circulatory collapse.
• D. A skin infection.

Answer: (C)

Shock is a life-threatening condition where the circulatory system fails to deliver enough blood to the body's tissues, causing organs to be underperfused. The statement that describes a sudden physical or mental collapse or circulatory collapse best captures this abrupt loss of blood flow and the serious impact it has on the whole body. It isn’t about a long-term fatigue, a brief spell of dizziness, or a skin infection—those describe different problems that don’t involve the rapid, systemic drop in perfusion that defines shock. In real life, this is an emergency requiring prompt attention: call for help, try to keep the person safe and still, and avoid giving food or drink if they’re not fully awake.
