Question: 1 / 400

Which pneumoconiosis occurs more frequently in the upper lobes of the lungs and is characterized by nodules?

Asbestosis

Silicosis

Pneumoconiosis refers to a group of lung diseases caused by inhaling dust or particles. Asbestosis and berylliosis primarily affect the lower lobes of the lungs, and coal workers' pneumoconiosis can affect both upper and lower lobes. Therefore, option B (Silicosis) is the only correct answer as it is known to predominantly affect the upper lobes of the lungs. Silicosis is caused by prolonged exposure to silica dust, typically from occupations such as mining and sandblasting. Symptoms include shortness of breath, coughing, and fatigue. It is important to note that all of the other options can also cause nodules in the lungs but are not as commonly associated with nodules in the upper lobes.
