In nerve agent exposure, convulsions are classified as which onset timing?

Explanation:
Convulsions after nerve agent exposure arise from a rapid acetylcholinesterase blockade, causing a sudden surge of acetylcholine in the central and peripheral nervous systems. This abrupt cholinergic crisis drives seizures within minutes of exposure, so the onset is best described as immediate. The other timeframes don’t fit because they refer to delays or durations rather than how quickly the seizures begin. In the acute response, recognizing the immediate onset helps prompt rapid seizure control, airway support, decontamination, and antidotal treatment.
