Strategic Thinking: A trauma reduces blood volume significantly. Which outcome best describes what happens if the cardiovascular system fails to provide sufficient circulation to every body part?
Hypoperfusion (shock) develops because tissues no longer receive adequate blood flow.
Blood pressure increases and perfusion improves throughout the body.
Only the digestive tract loses perfusion while other organs function normally.
