Sample item

Which spirometry pattern supports a diagnosis of obstructive airway disease?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Reduced FEV1/FVC ratio

Obstruction limits expiratory flow and lowers the FEV1/FVC ratio, as commonly seen in asthma and chronic obstructive pulmonary disease.

Option by option

  • A. Increased FEV1/FVC ratio from restriction

    Restriction often preserves or raises the ratio.

  • B. Reduced oxygen saturation alone

    Oxygen saturation is not a spirometric measurement.

  • C. Reduced FEV1/FVC ratio (correct)

    Correct: airflow obstruction lowers the ratio.

  • D. Normal ratio with no symptoms

    A normal ratio alone does not establish obstruction.
