All options (I. History, II. Chest X-ray, III. ABG, and IV. Comprehensive pulmonary function study) are useful in differentiating between obstructive and restrictive lung disorders, assessing their severity, and formulating a therapeutic plan. History can provide insight into symptoms and potential exposures; chest X-ray can show structural changes; ABG (arterial blood gases) can reveal gas exchange efficiency; and comprehensive pulmonary function tests can quantify the extent of obstruction or restriction.
