Questions and Answers

What is the primary pathophysiological component of syncope during dental extraction?

  • Cerebral ischemia due to inadequate oxygenated blood supply to the brain (correct)
  • Anxiety-induced redirection of blood flow from the brain to skeletal muscles
  • Increased volume of blood in skeletal muscles causing decreased blood supply to the brain
  • Decreased venous return to the heart leading to reduced cerebral blood flow

    • What signs and symptoms indicate a slight decrease in cerebral blood flow during syncope?

  • Increased heart rate, feeling weak, cold skin, sweating
  • Convulsions, pale skin, weakness, unconsciousness
  • Light headedness, dizziness, tachycardia, palpitation (correct)
  • Nausea, cold skin, sweating, loss of consciousness

    • How does anxiety contribute to the development of syncope during dental extraction?

  • Anxiety induces convulsions which lead to loss of consciousness
  • Anxiety causes an increase in cerebral blood flow resulting in fainting
  • Anxiety triggers an increase in heart rate leading to decreased blood supply to the brain
  • Anxiety leads to redirection of blood flow from the brain to skeletal muscles (correct)
