What is the primary clinical feature of exposure to phosgene oxime?

• A. Skin blistering (vesicant agent)
• B. Nausea and vomiting
• C. Eye irritation only
• D. Rapid fever

Answer: (A)

Phosgene oxime is a potent vesicant, so the defining feature after exposure is rapid, severe skin blistering where contact occurs. This agent cause quick tissue injury and large, painful blisters due to sudden cell damage, often with little initial pain but rapid progression. Nausea, vomiting, or fever can occur with exposure, and eye irritation can happen, but these are not the hallmark signs. In practice, the priority is immediate decontamination and wound care to limit blister formation and spread, along with monitoring for airway or eye involvement.
