The occupational lung disease caused by inhalation of coal

Appeared in: RUHS, Jaipur, M.Sc Nursing Entrance Exam-2022

Explanation

Pneumoconioses is the correct answer as it is the broad medical term for lung diseases resulting from the inhalation of dust.
The specific condition caused by inhaling coal dust is known as Coal Worker's Pneumoconiosis (CWP), or black lung disease.
Since Coal Worker's Pneumoconiosis is a type of pneumoconiosis, this option serves as the correct general classification among the choices provided.

Option B: Silicosis is caused by the inhalation of silica dust, which is found in sand, rock, and quartz.
Option C: Byssinosis is caused by exposure to dust from cotton, flax, or hemp.
Option D: Siderosis is caused by the inhalation of iron oxide dust or fumes.

Clinical Relevance

Nursing practice connection: Knowing Occupational lung diseases (Pneumoconioses) and their causative agents helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
A key nursing responsibility is to obtain a thorough occupational history from any patient presenting with chronic respiratory symptoms to identify potential hazardous exposures.
Nurses play a vital role in primary prevention by educating workers in high-risk industries about the importance of using personal protective equipment (PPE), such as masks and respirators.
What if? If the patient was a textile worker experiencing chest tightness that was worse at the beginning of the work week, the most likely diagnosis would be Byssinosis, not a pneumoconiosis related to mineral dust.

How to Approach the Question

This is a factual recall question that tests your knowledge of occupational health.
First, identify the keywords in the question stem: 'occupational lung disease' and 'inhalation of coal'.
Next, evaluate each option to determine the specific dust or substance that causes it.
Recall that Silicosis is from silica, Byssinosis from cotton, and Siderosis from iron.
Recognize that 'Pneumoconioses' is a general term for all dust-related lung diseases.
Since the specific disease from coal (Coal Worker's Pneumoconiosis) is a type of pneumoconiosis, and the other options are incorrect, select 'Pneumoconioses' as the best-fitting answer.
