A 78-year-old patient is admitted to the emergency department and is diagnosed with bradycardia. The patient tells the nurse he or she is taking donepezil (Aricept), a cholinergic agent, for Alzheimer's disease
The nurse will anticipate what drug will be ordered to treat the patient's bradycardia? A) Atropine
B) Pseudoephedrine
C) Propranolol
D) Bethanechol
A
Feedback:
Maintain a cholinergic blocking drug on standby, such as atropine, to use as an antidote for excessive doses of cholinergic drugs to reverse overdose or counteract severe reactions arising from use of cholinergic agonists. Atropine will block cholinergic effects that are causing this patient's heart rate to decline. Bethanechol will slow the heart rate further whereas propranolol and pseudoephedrine will not reverse the cholinergic stimulation.
