HSCi 204 Midterm Questions With
Complete Solutions

### Section 1: Foundational Concepts
**1. Describe environmental health.**
- A. The study of infectious disease transmission in hospital settings
- B. **Relationships between people and their environment and how this impacts quality of life**
- C. The process of diagnosing environmental allergies
- D. The study of workplace safety regulations only
*Rationale: Environmental health examines the interactions between people and their physical,
chemical, social, and psychological environments, with the goal of minimizing adverse health effects .*
**2. What is planetary health?**
,- A. A field focused exclusively on climate change mitigation
- B. **A new field that focuses on the health of civilians AND the natural systems they depend on**
- C. The study of healthcare systems across different countries
- D. A branch of astronomy studying habitable planets
*Rationale: Planetary health explicitly accounts for the importance of natural systems and recognizes
that human health is fundamentally dependent on the health of the planet's ecosystems .*
**3. How are planetary health and environmental health similar?**
- A. Both focus exclusively on occupational exposures
- B. **Both look at human health AND exposures outside of the body**
- C. Both ignore the role of social factors in health
- D. Both only study acute, immediate health threats
*Rationale: Both fields recognize that human health is influenced by factors and exposures originating
outside the body, whether from the built environment, natural systems, or chemical pollutants .*
**4. According to Hippocrates, what three things must we examine to understand the health of a
population?**
- A. Diet, exercise, and sleep
- B. Genetics, income, and education
- C. **The AIR people breathe, the WATER people drink, and the PLACES people live**
- D. Age, gender, and occupation
, *Rationale: The ancient Greek physician Hippocrates recognized the connection between environment
and health over two thousand years ago, emphasizing the importance of air, water, and place .*
**5. What did Paracelsus mean by "the dose makes the poison"?**
- A. All chemicals are equally toxic regardless of dose
- B. **All things are poison; it is only the dose that makes a thing not a poison**
- C. Higher doses of medication are always more effective
- D. Only synthetic chemicals can be toxic at certain doses
*Rationale: Paracelsus, considered the father of toxicology, established the fundamental principle that
any substance can be toxic if the dose is high enough, and conversely, even highly toxic substances may
be harmless at very low doses .*
**6. Historically, information about environmental health hazards came from two main sources. What
are they?**
- A. Randomized controlled trials and laboratory experiments
- B. **Anecdotal occupational observations AND disasters/sudden unexpected events**
- C. Pharmaceutical company reports and government databases
- D. Patient surveys and hospital records
*Rationale: Early environmental health knowledge came from observing workers who experienced rare
diseases with unexpected frequency (like chimney sweeps with scrotal cancer) and from sudden
disasters that caused dramatic health changes in populations (like Minamata) .*
**7. What was the first environmental carcinogen identified, and who discovered it?**
