Question

A condition which results from exposure to welding fumes that is characterized by accumulation of metal oxides in the lung without apparent physical symptoms is called:

A)
Pulmonary atresia

B)
Siderosis

C)
Idiopathic pulmonary distress

D)
Byssinosis

Answer 1

Siderosis is the correct answer to the question, and it is a type of occupational lung disease typically caused by inhaling metal dust or fumes, like those from welding.

Step-by-step explanation:

The condition that results from exposure to welding fumes and is characterized by the accumulation of metal oxides in the lung, usually without apparent physical symptoms, is B) Siderosis. Siderosis is an example of an occupational lung disease caused by the inhalation of dust or fumes containing iron or other metals. Unlike other more severe pneumoconiosis conditions, siderosis typically does not lead to significant pulmonary dysfunction, although it can be identified through radiologic exams as deposits in the lungs.

Hypersensitivity pneumonitis, also an occupational disease, occurs when the lungs become inflamed due to an allergic reaction to inhaled substances. This is different from siderosis because hypersensitivity pneumonitis is caused by an allergic reaction and can lead to symptoms like coughing and difficulty breathing.
