الإجابة: C. A spirometry post bronchodilators FEV1/FVC less than 70%
COPD is confirmed by spirometry showing a post-bronchodilator FEV1/FVC <70% (persistent airflow limitation). Wheeze, BMI and clubbing are not diagnostic.

A
ليش غلط
Body habitus varies in COPD (thin in emphysema, overweight in chronic bronchitis), so BMI is not what diagnoses it.

ليش غلط
Nail clubbing is not specific to COPD; it usually suggests comorbidities such as bronchiectasis, pulmonary fibrosis or lung cancer.

A post-bronchodilator FEV1/FVC below 70% confirms the diagnosis of COPD.

Wheeze and a prolonged expiratory phase are only listed among the presenting auscultation findings (with crackles and muffled breath sounds), not as what confirms COPD.
