In managing suspected organophosphate poisoning in the field, the most critical initial action is to

• A. Decontaminate the patient before securing the airway
• B. Give activated charcoal
• C. Obtain a detailed exposure history
• D. Secure the airway and provide supportive care first

Answer: (D)

In organophosphate poisoning, the immediate danger is respiratory compromise from excessive secretions and bronchospasm due to acetylcholinesterase inhibition. Securing the airway and providing supportive care to maintain ventilation and oxygenation must come first, because hypoxia can occur rapidly and become life-threatening. In the field, this means assessing breathing, administering high-flow oxygen, suctioning to clear secretions, and assisting ventilation if needed, with readiness to advanced airway support. Decontamination and other steps are important, but delaying airway management to decontaminate or obtain a history risks rapid deterioration. Activated charcoal has limited role in this scenario and does not address the acute threat to breathing.
