An individual having been in the hot sun all day complains of weakness and nausea. When should you call 911?

When they start to shiver
When they show signs of dehydration
When they have a change in the level of consciousness
When they feel dizzy

The correct answer is: When they have a change in the level of consciousness

When an individual shows a change in their level of consciousness, it indicates a serious condition that requires immediate medical attention. This could be a sign of heat-related illnesses such as heat exhaustion or heat stroke, which can compromise the body's ability to regulate temperature and lead to potential life-threatening complications. In the context of sun exposure and the symptoms of weakness and nausea, a change in consciousness might manifest as confusion, disorientation, or unresponsiveness. These symptoms suggest that the body's systems are under significant stress and that the individual may be at risk for more severe complications, making it critical to seek emergency assistance promptly. While other symptoms like dizziness or dehydration are concerning and may require intervention, they do not carry the same immediacy or seriousness of a change in consciousness, which warrants calling 911 without delay.
