What is a normal blood PaCO2level?
  1. 60mm Hg- 65mm Hg
  2. 80mm Hg- 90mm Hg
  3. 35mm Hg- 55mm Hg
  4. 15mm Hg- 25mm Hg
Explanation
Answer: C - A normal blood PaCO2 level is 35-45mm Hg. Increasing the PaCO2causes cerebral vasodilation, while decreasing it results in cerebral vasoconstriction. If the patient is poorly ventilated, the PaCO2will increase, causing even further vasodilation with a subsequent increase in intracranial pressure.
