Which item is used to indicate the level of treatment given after nerve agent exposure?

• A. Writing in the patient chart
• B. Attaching used injectors to casualty's blouse
• C. Placing a badge on the belt
• D. Informing bystanders

Answer: (B)

In a nerve agent incident, quickly showing what treatment has already been given is crucial for the next caregiver. Attaching the used auto-injector to the casualty’s blouse creates a visible, on-person marker that clearly signals that antidote treatment has been administered. This immediate cue helps field medics avoid duplicating doses, assess how many doses were given, and tailor further care right away, without needing to hunt through charts. While writing notes in the chart is important, it isn’t as accessible to responders in the field, and options like a belt badge or informing bystanders don’t reliably convey treatment status.
