What is one of the symptoms of poisoning?

Nausea and vomiting are common symptoms associated with poisoning. When a person ingests toxic substances, their body often reacts by trying to expel the harmful agents, leading to gastrointestinal disturbances. This is a protective mechanism, as the body aims to reduce the absorption of the poison. In cases of poisoning, other symptoms may also arise, but nausea and vomiting are frequently among the first indications, prompting rapid medical attention.

The other options, while they may be related to various medical conditions, do not specifically characterize symptoms of poisoning as directly as nausea and vomiting do. Chest pain can indicate a range of issues, including heart-related problems, while rapid heartbeat may suggest stress or other medical emergencies. High fever typically indicates an infection or inflammatory response rather than poisoning. Thus, the association of nausea and vomiting with poisoning is much clearer and widely recognized in medical training and first aid protocols.
