DOT Certification Practice Exam

Which condition is considered disqualifying for certification?

1. Asthma with infrequent hospitalizations

2. COPD with severe cough

3. Controlled hypertension

4. Chronic bronchitis

The correct answer is: COPD with severe cough

The condition that is considered disqualifying for certification in this context is COPD with severe cough. Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung disease that can significantly impair lung function, leading to difficulty in breathing and reduced exercise tolerance. When a person with COPD experiences a severe cough, it often indicates a more advanced stage of the disease which can exacerbate breathing difficulties, especially during physical exertion. This poses a considerable risk for individuals in safety-sensitive positions, especially in transportation, where sudden health issues could result in dangerous situations. In contrast, conditions such as asthma with infrequent hospitalizations may be manageable and not present a continuous risk to health. Controlled hypertension involves maintaining blood pressure within a normal range, indicating that the condition does not pose an immediate threat. Chronic bronchitis can vary in severity; if not associated with acute exacerbations or significant limitations, it may not automatically disqualify an individual. Thus, the severity and impact of symptoms, particularly in the case of COPD with severe cough, make it a disqualifying factor for certification.
