ANS: B
A. Incorrect response: See explanation B.
B. Correct response: Positive-pressure ventilation can have a detrimental effect on the CPP if the ventilatory strategies lead to either a rise in ICP or a drop in MAP. Performing endotracheal suctioning, coughing, and manipulating airway pressure can induce a rise in ICP. Positive-pressure ventilation and PEEP tend to decrease venous return to the right ventricle, which can lead to a decrease in the MAP.
