Question

which of the following may cause restrictive lung disorder?
multiple choice
asthma
bronchitis
lung fibrosis
emphysema

Explanation:

Restrictive lung disorders are characterized by a reduced ability of the lungs to expand. Lung fibrosis involves the formation of scar tissue in the lungs, which restricts lung expansion. Asthma, bronchitis, and emphysema are obstructive lung disorders (they involve airway narrowing or obstruction rather than restriction of lung expansion).

Answer:

Lung fibrosis.
