For organophosphate toxicity, which of the following is used as the antidote to decrease secretions and ventilatory resistance?

Explanation:
Organophosphate poisoning causes an excess of acetylcholine at muscarinic receptors, leading to increased secretions and bronchospasm that make ventilation difficult. Atropine is a muscarinic antagonist, so it blocks these receptor effects, drying secretions and reducing bronchoconstriction to improve ventilation. While pralidoxime reactivates acetylcholinesterase to help with nicotinic symptoms like muscle weakness, it isn’t the primary agent for the secretions and ventilatory resistance. Diazepam may be used for seizures, and oxygen provides support, but atropine specifically targets the airway secretions and bronchial constriction.
