A nurse is planning care for a client who is scheduled to receive electroconvulsive therapy (ECT). Which of the following medications should the nurse anticipate administering prior to the procedure?

A. Atropine is an anticholinergic commonly administered before ECT to decrease secretions and reduce the risk of bradycardia during the procedure. B. Diphenhydramine is an antihistamine used for allergies or mild sedation but is not indicated in the ECT pre-procedure protocol. C. Fluoxetine is an SSRI used for depression but should typically be held or managed carefully in clients receiving ECT, as some antidepressants can interfere with seizure threshold. D. Epinephrine is used in emergency situations such as anaphylaxis or cardiac arrest and is not part of the routine pre-ECT medication regimen.
