A man has been a coal miner for 30 years. For the past 3 years, he has had progressively worsening dyspnea and has been diagnosed with a form of pneumoconiosis. Which information applies to his condition and should provide the basis for appropriate client teaching

His decreased residual volume and decreased lung compliance contribute to his altered ventilation.

Explanation:

Pneumoconioses are distinguished by reduced residual volume and impaired compliance with the lungs.

Pneumoconiosis involves asbestosis, silicosis, and the pneumoconiosis (CWP) of coal workers.

The most prevalent mineral dusts proven to cause pneumoconiosis in the workplace are asbestos, silica (rock and sand dust), and coal dust.

Cough and shortness of breath are by far the most common symptoms of pneumoconiosis. The threat is usually greater when people are exposed to high levels and/or long periods of time from mineral dusts.

One risk factor is the insufficient or inconsistent usage of personal protective equipment (PPE) such as respirators (specially designed breathing masks), as avoiding inhalation of dusts would also avoid pneumoconiosis.

There is a decrease in the volume of air that remains in the lungs after maximum forceful expiration by the man which cannot be expired and a decreased ability for the lungs to stretch and expand which contributed to his altered/unchanged respiration.

Normal adult lung compliance ranges from 0.1 to 0.4 L/cm H20, and it is measured under static conditions(conditions of no flow).

digital rectal exam (dre) a digital rectal exam (dre) is a test for both men and women. it allows a doctor to check the lower rectum, pelvis, and lower belly for cancer and other health problems, including: prostate cancer in men.
