Question

Pneumoconiosis is a type of
a. Emphysema
b. Occupational renal disease
c. Occupational respiratory disease
d. Coronary artery disease

Answer 1

Hint: Due to inhalation of particular dust particles over the period lungs become scarred. This condition is known as pneumoconiosis. There are several types of Pneumoconiosis are found, named aluminous, silicosis, siderosis, byssinosis etc.

Complete answer:
> Option A: Emphysema: It is the condition in which the inner wall of alveoli becomes damaged over the time which results in the formation of larger air spaces within the alveoli. Larger spaces of alveoli prevent the entry of enough air during respiration. Thus it creates prevention in the entry of oxygen-rich air into the lung that leads to the reduction of oxygen in the blood. The major symptom of emphysema is the shortness of breath.

> Option B: Occupational renal disease: due to exposure of the particular compound over the time it leads to chronic kidney disease which is known as occupational renal disease.

> Option C: Pneumoconiosis is a type of occupational respiratory disease. It is the result of the inhalation of certain particles for a longer period. Symptoms of occupational respiratory disease are runny nose, breathing problem, chest pain, cough, muscle and body ache etc.

> OPtion D: Coronary artery disease is the result of a blockage in the hearts' major blood vessels. The blockage may be the result of plaque formation within the vessels which leads to the prevention of blood flow within the artery. Symptoms of coronary artery disease are chest pain, heart attack etc.

Hence, the correct answer is option (C).

Note: Pneumoconiosis is a non-curable disease. This disease is mainly found in coal workers and it is known as black lung disease. Pneumoconiosis caused by cotton fibre inhalation is known as brown lung disease.
