The ____ has an opening at the distal end which allows removal or aspiration of air and gastric contents from the stomach via a gastric tube.

What is the influence of an increased lung volume on the right ventricle?

A. increased preload B. increased afterload C. increased myocardial contractility D. increased cardiac output

What conclusions were drawn from the Acute Respiratory Distress Syndrome Network (ARDSnet) study regarding ventilator-induced lung injury?

A. The tidal volume used to ventilate a patient is not as important as the pressure delivered to the lungs. B. Low tidal volume ventilation attenuates ventilator-induced lung injury (VILI). C. Plateau pressure levels are the most important consideration in preventing VILI. D. PEEP levels used in conjunction with mechanical ventilation are the most important consideration in minimizing VILI?
