AACN practice questions with correct answers


hyperresonace and dullness over lung indicates... - Ans:✔✔-hyperresonance= air


dullness= fluid


decreasing the TV on ventilator will do what to co2? - Ans:✔✔-increase co2


The major effect of ARDS on lung tissue is - Ans:✔✔-Decreased compliance




Decreased compliance is related to alteration of lung endothelium and vascular tissue. Pathophysiologic

changes in lung vascular tissue and increased lung edema contribute to the decrease in compliance. The

end result is stiffness of the fluid-filled non-aerated airways. There is an increase in capillary permeability

due to the release of cytokines and a decrease in functional residual capacity due to pathophysiologic

changes in the lung. The inflammatory process of ARDS causes inactivation, destruction and decreased

production of surfactant. This leads to increased surface tension at the alveolar air-fluid interface, which

causes microatelectasis.
