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

Dobutamine

Atropine sulfate

Atenolol

Bethanechol

Answer and Explanation

The Correct Answer is B

A.   Dobutamine is a sympathomimetic drug used to increase cardiac output in conditions such as heart failure. It is not an antidote for cholinergic drug overdose.
B.   Atropine sulfate is the antidote for cholinergic drug overdose. It acts as a competitive antagonist to acetylcholine at muscarinic receptors, counteracting the effects of excessive cholinergic stimulation.
C.   Atenolol is a beta-blocker used to manage hypertension and certain cardiac conditions. It is not an antidote for cholinergic drug overdose.
D.   Bethanechol is a cholinergic agonist used to stimulate bladder contractions in urinary retention. It is not an antidote for cholinergic drug overdose; in fact, it would exacerbate cholinergic effects.
