QUESTION
Antidote for organophosphorus poisoning is?
OPTIONS
(A) Edrophonium
(B) Pralidoxime
(C) Vitamin K
(D) Nalorphine
ANSWER
(B) Pralidoxime
EXPLANATION
Pralidoxime reactivates acetylcholinesterase phosphorylated by organophosphorus compounds, particularly when given early, and is used with atropine. Edrophonium is a cholinesterase inhibitor, vitamin K treats selected coagulopathies, and nalorphine is an opioid antagonist rather than an organophosphate antidote.
