What symptoms are typical after exposure to OC spray?

• A. Nausea and vomiting
• B. No effect on mucous membranes
• C. Burning, tearing, coughing, and temporary blindness
• D. Dizziness and headaches only

Answer: (C)

Exposure to OC spray irritates exposed tissues, especially the eyes and mucous membranes. The typical immediate effects are burning in the eyes, tearing, coughing, and temporary blurred vision or temporary blindness as the cornea and conjunctiva react. This matches the presented option, which lists those symptoms. Nausea and vomiting aren’t the primary immediate reactions and aren’t caused by mucosal irritation in the same way; there is usually a strong local irritation rather than a systemic upset. Dizziness or headaches can occur for some people, but they don’t capture the core immediate signs of OC spray exposure, which are the eye burning, tearing, coughing, and temporary vision loss. The combination described reflects the characteristic response to OC spray.
