A nurse is preparing to teach a client who has major depressive disorder and is scheduled to undergo electroconvulsive therapy (ECT). Which of the following statements should the nurse include in the teaching?

A. "ECT is contraindicated in clients who have psychotic symptoms." ECT is actually an effective treatment for severe depression with psychotic features, as well as treatment-resistant schizophrenia. It is not contraindicated in these cases; rather, it is often recommended when medications are ineffective. B. "ECT is delivered through electrodes attached to the head." During ECT, electrical stimulation is applied via electrodes placed on the scalp to induce a controlled seizure. This process alters brain chemistry and can rapidly improve severe depressive symptoms, making this statement accurate. C. "ECT cannot be administered to clients who have suicidal ideation." ECT is commonly used in individuals with severe suicidal ideation, particularly when rapid symptom relief is needed. It can be life-saving in cases of severe, treatment-resistant depression, making this statement incorrect. D. "ECT is conducted under regional anesthesia." ECT is performed under general anesthesia, not regional anesthesia. The client receives short-acting anesthesia along with a muscle relaxant to prevent injury during the induced seizure.
