Which of the following is a sign of chemical agent exposure?

Chemical agent exposure can lead to a variety of symptoms depending on the specific agent and the level of exposure. Neurological symptoms, such as confusion or seizures, are significant indicators of this type of exposure because many chemical agents impact the central nervous system. For example, organophosphate nerve agents can disrupt normal neurotransmission, leading to symptoms that affect cognitive functioning and neural stability.

These neurological effects come from the disruption of acetylcholine regulation, resulting in overstimulation of neurons. Consequently, symptoms like confusion, disorientation, and seizures can be direct manifestations of the nervous system being compromised. Recognizing these signs is critical for first responders and medical personnel, as quick intervention can help mitigate the severe impacts of chemical exposure on the brain and overall health.

In contrast, while increased heart rate and elevated blood pressure can be signs of stress or agitation related to various medical issues, including trauma or anxiety, they are less specific to chemical exposure. Reduced body temperature is also typically not a recognized symptom of chemical agent exposure, as most chemical agents would not lead to hypothermia.
