When blood flow to the brain is restricted, which of the following can happen?
  1. CVA
  2. TIA
  3. Both A and B
  4. Neither A nor B
Explanation
Answer - C - When blood flow to the brain is restricted, one of two conditions can occur. A TIA, or trans-ischemic attack, results in temporary blood flow loss, but does not have much long term damage. CVA, or cerebrovascular accident (also known as a stroke), has greater damage, as it can actually kill brain tissue.
