The following pulmonary function results were obtained: TLC 3.0 L 70% predicted DLCO 12.0 55% predicted FEV₁2.0 L FVC 2.3 L The results are consistent with: A) Interstitial lung disease B) Emphysema C) Asthma D) Neuromuscular disease

Question

The reduced TLC and DLCO suggest interstitial lung disease, which is characterized by stiffness or scarring of the lung tissue, leading to reduced lung volumes and impaired gas exchange. The FEV1/FVC ratio is not provided, so it's not possible to definitively rule out other conditions like emphysema or asthma. Neuromuscular disease would be unlikely to cause only a reduction in lung volumes and gas exchange.
