Occupational and Environmental Health: Recognizing and Preventing Disease and Injury - Multiple Choice Questions - Learn & Prevent

What altitude is generally considered when the risk of altitude sickness significantly increases?

1. 1,000 meters (3,280 feet)

2. 2,500 meters (8,202 feet)

3. 5,000 meters (16,404 feet)

4. 7,500 meters (24,606 feet)

The correct answer is: 2,500 meters (8,202 feet)

An altitude of 2,500 meters (8,202 feet) is generally considered the threshold at which the risk of altitude sickness significantly increases. This is because as you ascend to higher altitudes, the air becomes thinner and contains less oxygen, making it more difficult for your body to function properly. While higher altitudes do pose an increased risk for altitude sickness, they are not typically reached by most travelers and thus were not included as options in this question. As for the lower altitudes, while they may cause some discomfort and symptoms of altitude sickness, the risk is not considered significant enough to be included as the correct answer. Therefore, option B is the most appropriate and accurate answer to the question.
