A nurse is assessing a client who has been receiving electroconvulsive therapy. Which of the following findings indicates the treatment is effective?

Choice A reason: Electroconvulsive therapy (ECT) isn’t a primary treatment for borderline personality disorder, which relies on psychotherapy like DBT. ECT targets severe mood disorders, not personality traits like emotional instability. Improvement in BPD symptoms wouldn’t indicate ECT efficacy, as it’s not the intended outcome. This finding misaligns with ECT’s clinical purpose. Choice B reason: Reduced seizure frequency relates to epilepsy management, not ECT, which induces controlled seizures to treat psychiatric conditions. Effectiveness isn’t measured by fewer spontaneous seizures but by mood improvement. This outcome reflects a misunderstanding of ECT’s mechanism, making it an incorrect indicator of success. Choice C reason: ECT is primarily used for severe depression, especially when medications fail, by altering brain chemistry via induced seizures. Improvement in depressive symptoms—elevated mood, energy, or appetite—directly indicates efficacy, aligning with its therapeutic goal. This finding confirms ECT’s intended effect, making it the correct measure. Choice D reason: Decreased fear of heights suggests phobia improvement, treated by exposure therapy, not ECT. ECT focuses on mood disorders, not specific anxiety conditions unrelated to depression. This outcome doesn’t reflect ECT’s purpose or mechanism, so it’s not a valid indicator of treatment success here.
