Question 1 of 5

A client is experiencing a cholinergic crisis after being administered pyridostigmine IV. The nurse should administer which of the following reversal agents?

Correct Answer: D

Rationale: The correct answer is D: Atropine. Atropine is the antidote for cholinergic crisis as it competitively inhibits acetylcholine at muscarinic receptors, counteracting the excessive cholinergic effects caused by pyridostigmine. Galantamine (
A) is an acetylcholinesterase inhibitor and would worsen the symptoms. Physostigmine (
B) is used to treat anticholinergic toxicity, not cholinergic crisis. Flumazenil (
C) is a benzodiazepine receptor antagonist and is used for benzodiazepine overdose, not cholinergic crisis.
