FEV1/FVC decreases and compliance increases, D. FEV1/FVC increases and compliance decreases', 'role': 'user'}, {'content': 'Answer: D \nExplanation: Answer is D (FEVI/FVC increase and compliance decreases): Restrictive lung diseases are characterized by decreased compliance and increased FEVIFI"C FENT\' & FVC Forced Vital Capacity (FVC) is decreased Forced expiratory flow rates are relatively preserved (FEV1 is preserved) FEV1 / FVC When FEVI is considered as a percentage of FVC, the flow rates tend to become supranormal or dispropoionately high relative to size of lungs. FEV", is preserved and FVC is decreased so FEV / IFTC is increased The hallmark of restrictive lung diseases is a decrease in lung volumes primarily TLC and V.C.\' (FVC is decreased)-Harrison Compliance decreases in restrictive lung disease. Compliance is usually unaffected in obstructive lung diseases except in emphysema where it is increased.', 'role': 'assistant'}]
