If an animal experiences shock, which outcome is most accurate?

If an animal experiences shock, which outcome is most accurate?

• A. The peripheral circulation fails.
• B. The body temperature increases.
• C. Nerve signals cannot respond.
• D. A blood clot lodges in the brain.

Answer: (A)

During shock, the body's circulation cannot deliver enough blood to tissues, so peripheral circulation fails. This reduces tissue perfusion and oxygen supply to the skin and organs, which is the core issue in shock and leads to potential organ dysfunction if not corrected. The other statements don’t fit as the defining consequence: body temperature is not typically increased—in fact, hypothermia is common due to poor perfusion and heat loss; nerve signals can still be transmitted when there is some blood flow, so claiming they cannot respond is not accurate; and a blood clot lodging in the brain describes a stroke, a specific event not the general outcome of shock.
