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?

A) Temporary memory loss: Temporary memory loss is a well-known and common side effect following electroconvulsive therapy (ECT). Clients may experience short-term memory issues, such as forgetting events that occurred around the time of the procedure or difficulties recalling information. This side effect is usually temporary and tends to resolve as the brain recovers from the procedure. B) Voice alteration: Voice alteration is not a typical side effect of electroconvulsive therapy. ECT primarily affects brain function, particularly memory and cognitive processes, and does not have a direct effect on the voice or vocal cords. C) Tingling of the scalp: Tingling of the scalp is not a common adverse reaction to electroconvulsive therapy. While there may be some minor physical sensations or discomfort during the procedure, tingling is not a typical side effect associated with ECT. D) Neck pain: Neck pain is not a usual adverse reaction of electroconvulsive therapy. Some discomfort might occur after the procedure due to muscle tension or the positioning during the therapy, but it is not a common or prominent side effect like memory loss.
