[Answer] A pt has emphysema. Which clinical findings will the nurse most likely observe when reviewing the results of the pulmonary fxn tests? Select all that apply.A. Decreased residual volumeB. Decreased forced vital capacityC. Decreased forced expiratory flowD. Increased functional residual capacityE. Increased forced expiratory volume in one second

Answer: B. Decreased forced vital capacityC. Decreased forced expiratory flowD. Increased functional residual capacityEmphysema is a lung disease caused by inflammation and damage to the alveolar walls. Due to the decreased elasticity of the lung tissue the forced vital capacity will be 50% of the normal value and the forced expiratory flow will be 25% of the normal value. The functional residual capacity increases up to 200% over the expected amount as a result of the air trapped in the alveoli. Due to damage to the alveolar walls the residual volume may be increased to four times the normal finding. A patient with emphysema may have only 25% to 35% of the predicted value of forced expiratory volume in one second.
