In CHEMPACK management, how many Atropine/Pralidoxime doses are given for severe exposure?

• A. 3 doses Atropine/Pralidoxime Chloride
• B. 1 dose
• C. 2 doses
• D. 0 dose

Answer: (A)

Severe exposure from nerve agents requires repeated antidotal treatment because the ongoing cholinergic effects can persist despite the first dose. The CHEMPACK protocol uses three doses of atropine with pralidoxime for severe cases, administering them at intervals (often every 10–15 minutes) until clinical improvement is evident. Each dose counteracts muscarinic symptoms and secretions with atropine while pralidoxime begins to reactivate acetylcholinesterase. If symptoms remain after three doses, additional medical care and more advanced treatment are required.
