A nurse is reinforcing teaching with a client who is about to undergo electroconvulsive therapy. The nurse should explain to the client that which of the following adverse reactions can occur following the procedure?

Choice A reason: Voice alteration isn’t linked to ECT; it affects brain function, not vocal cords. Post-procedure, neurological effects dominate, not laryngeal changes.Choice B reason: Neck pain may occur from positioning, but it’s not a primary ECT reaction. Muscle relaxants minimize strain, making this less common.Choice C reason: Scalp tingling could stem from electrodes, but it’s rare and minor. ECT’s electrical impact targets memory and mood, not sensory nerves.Choice D reason: Temporary memory loss is a well-documented ECT side effect, from disrupted hippocampal function. It’s expected, often resolving, and key to inform clients.
