A nurse is caring for a client who has major depressive disorder and is scheduled for electroconvulsive therapy (ECT). The client's spouse asks the nurse about the possible side effects of the ECT. Which of the following responses should the nurse make?

A. While anesthesia is used during ECT, the most common side effects are related to the procedure itself, not directly to anesthesia. This response does not fully address the common side effects. B. This is the most accurate response. The main side effects of ECT are temporary and often include mild confusion, headaches, and short-term memory loss, which are common and typically resolve after treatment. C. While rare, myocardial infarction can occur during any procedure requiring anesthesia, but it is not considered a primary risk associated with ECT. This response might cause unnecessary concern. D. While muscle cramping can occur during the induced seizure, this is not one of the most common side effects. The primary concerns are related to memory and confusion, and this response does not address those risks appropriately.
