Which of the following symptoms does NOT align with exposure to a nerve agent?

• A. Pinpoint pupils
• B. Runny nose
• C. Severe skin irritation
• D. Difficulty breathing

Answer: (C)

Exposure to nerve agents typically results in a variety of acute symptoms that affect the nervous system and other bodily functions. Among these symptoms are pinpoint pupils, which indicate excessive stimulation of the parasympathetic nervous system; a runny nose, as a result of bronchial secretions and increased mucus production; and difficulty breathing, which occurs due to respiratory muscle paralysis and constriction of the airways.

Severe skin irritation is more commonly associated with chemical agents that cause corrosive effects on the skin, such as blister agents or other hazardous substances. Nerve agents do not primarily cause severe dermal reactions but rather work through their action on the nervous system, which leads to the other described symptoms. Therefore, the correct option reflects a symptom that does not typically occur with nerve agent exposure.
