What is shock?

What is shock?

• A. A temporary loss of consciousness due to dehydration
• B. A state of collapse caused by severe bleeding, burns, stomach injuries, etc.
• C. A mild fatigue after exercise
• D. An allergic reaction

Answer: (B)

Shock is a life-threatening state in which not enough blood is reaching the organs, so tissues don’t get enough oxygen and nutrients to function. It typically follows significant fluid or blood loss or severe injury, burns, or trauma, which lowers the volume of circulating blood and disrupts circulation. Because the body can’t maintain proper perfusion, you see signs like cold, pale skin; rapid pulse and breathing; dizziness or confusion; and, in severe cases, fainting or very low blood pressure. This is different from a temporary loss of consciousness due to dehydration or from mild fatigue after exertion. An allergic reaction can lead to a form of shock (anaphylactic shock) if it becomes severe, but the description given points to the broader, classic scenario of collapse from major blood/ fluid loss or tissue injury, which is the hallmark of shock.
