Answer to Question 1

ANS: D
The factors of positive-pressure ventilation that may decrease the systemic diastolic pressure are high mean airway pressure, due to a high positive end expiratory pressure, high tidal volume, or long inspiratory time.

Answer to Question 2

ANS: B
When mechanical hyperventilation is used, CVR increases, and the result is decreased ICP.
