Questions and Answers

What effect does pressure on the frontal lobes or deep midline structures have on respiratory patterns?

  • It causes hyperventilation.
  • It leads to Cheyne-Stokes respirations. (correct)
  • It results in irregular breathing that may eventually cease.
  • It induces apnea.

    • Why is coughing discouraged in patients with poor oxygenation?

  • It helps clear secretions from the lungs.
  • It prevents the development of Cheyne-Stokes respirations.
  • It improves venous drainage of the brain.
  • It can lead to an increase in intracranial pressure (ICP). (correct)

    • How does pressure in the midbrain affect respiration?

  • It results in irregular breathing that may eventually cease.
  • It leads to Cheyne-Stokes respirations.
  • It induces apnea.
  • It causes hyperventilation. (correct)
