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) is not typically used to reduce the frequency of seizures. In fact, ECT induces controlled seizures as part of its therapeutic process. Therefore, a reduction in seizure frequency is not an indicator of ECT's effectiveness. Choice B reason: While ECT can be used to treat various psychiatric conditions, it is most commonly and effectively used for severe depression. It is not primarily indicated for reducing the frequency of panic attacks. Therefore, a reduction in panic attacks is not a primary measure of ECT's effectiveness. Choice C reason: Improvement in manifestations of depression is a key indicator of ECT's effectiveness. ECT is often used when other treatments for major depressive disorder have failed. Patients typically show significant improvement in mood, energy levels, and overall functioning after a series of ECT treatments. Choice D reason: Decreased fear of heights, or acrophobia, is not a condition typically treated with ECT. Phobias are usually addressed through therapies such as cognitive-behavioral therapy (CBT) rather than ECT. Therefore, a decrease in the fear of heights is not an indicator of ECT's effectiveness.
