Sample item

What is the principal health risk from indoor biomass smoke exposure?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Chronic respiratory disease and pneumonia risk

Indoor biomass combustion releases fine particles and carbon monoxide, increasing respiratory infections and chronic lung disease, especially in poorly ventilated homes.

Option by option

  • A. Improved lung growth

    Smoke does not improve lung growth.

  • B. Chronic respiratory disease and pneumonia risk (correct)

    Correct: particulate smoke damages respiratory health.

  • C. Reduced carbon monoxide exposure

    Biomass smoke can increase carbon monoxide exposure.

  • D. Prevention of asthma symptoms

    It can exacerbate rather than prevent respiratory symptoms.
