Answer to Question 1

A, B, D
Three processes are involved in respiration: ventilation, mechanical movement of gases into and out of the lungs; diffusion, movement of O2 and CO2 between the alveoli and the red blood cells; and perfusion, distribution of red blood cells to and from the pulmonary capillaries.

Answer to Question 2

A, B
Best practice guidelines indicate that the following interventions are advantageous in preventing VAP: elevating the head of the bed at 30 to 45 degrees to prevent aspiration, changing patient position every 2 hours to decrease risk for atelectasis and pulmonary infection, providing oral care with a toothbrush every 8 hours to remove dental plaque organisms (toothettes are not adequate to clean dental plaque, but they may be used between brushings for comfort), maintaining the endotracheal cuff pressures at 20 cm H2O to decrease movement of secretions to the lower airways, and carefully monitoring the patient for aspiration when enteral feedings are infusing.
