What term describes substances used in chemical warfare?

• A. Biological Agents
• B. Chemical Agents
• C. Toxidromes
• D. Neuromuscular Blockers

Answer: (C)

The key idea is distinguishing between what describes the substances versus the effects they produce. Substances used in chemical warfare are called chemical agents. These are the actual chemicals deployed to cause harm or incapacitation, including nerve agents, choking agents, blistering agents, and pulmonary irritants. Toxidromes, by contrast, describe the pattern of symptoms that result from exposure to a toxin, not the substance itself. They help clinicians recognize the likely toxin class and guide management, but they are not the name for the agents used in warfare. Biological agents refer to organisms or their toxins used in biological warfare, and neuromuscular blockers are a specific class of drugs that can cause paralysis but aren’t the umbrella term for chemical warfare substances. So the correct term describing substances used in chemical warfare is chemical agents.
