Which statement describes shock?

Which statement describes shock?

• A. Heart rate increases
• B. Breathing stops
• C. Blood is not adequately getting to the blood cells
• D. Temperature is too high

Answer: (C)

Shock is a condition in which the circulatory system fails to deliver enough blood to the body's tissues, so those tissues don’t get the oxygen and nutrients they need to function. The best way to state that idea is that blood is not adequately getting to the tissues (the cells), meaning tissue perfusion is insufficient. When perfusion falls short, cells switch to less efficient metabolism, leading to energy failure and potential organ damage if not corrected. Signs like an increasing heart rate or rapid breathing often accompany shock as the body tries to compensate, but they are responses rather than defining features. Breathing stopping describes respiratory arrest, not shock itself, and a temperature being too high isn’t a defining characteristic of shock.
