Question 1 of 5

A patient has had an overdose of an intravenous cholinergic drug. The nurse expects to administer which drug as an antidote?

Correct Answer: B

Rationale: The correct answer is B: Atropine sulfate. Atropine is used as an antidote for cholinergic drug overdose because it acts as a competitive antagonist at muscarinic acetylcholine receptors. By blocking these receptors, atropine can counteract the excessive cholinergic stimulation caused by the overdose. Dobutamine (
A) is a beta-adrenergic agonist and not used in this context. Atenolol (
C) is a beta-blocker and not an antidote for cholinergic overdose. Bethanechol (
D) is a cholinergic agonist and would worsen the symptoms of overdose.
