2
Rationale 1: Atropine is not useful as treatment for exposure to ionizing radiation.
Rationale 2: Chemicals in nerve gas cause overstimulation by the neurotransmitter acetylcholine. Atropine blocks the attachment of this neurotransmitter to receptor sites.
Rationale 3: Atropine is not useful as treatment for exposure to bacterial agents.
Rationale 4: Atropine is not useful as treatment for exposure to viral agents.
Global Rationale: Chemicals in nerve gas cause overstimulation by the neurotransmitter acetylcholine. Atropine blocks the attachment of this neurotransmitter to receptor sites. Atropine is not useful as treatment for exposure to ionizing radiation, bacterial agents, or viral agents.
