Question

A client scheduled for electroconvulsive therapy asks the nurse how the therapy helps relieve her depression. The nurse's response is based on anderstanding that ECT: A. Eliminates the neurotransmitter acetylcholine B. Increases the perception of external stimuli C. Decreases levels of cortisol from the adrenal cortex D. Produces a seizure that temporarily alters brain chemicals

Short answer

Answer: ECT works by producing a seizure that temporarily alters brain chemicals.

Step-by-step solution

Identifying Key Information

To answer this question correctly, it is important to understand the mechanism of action of electroconvulsive therapy in treating depression. ECT is known to work by producing a seizure that temporarily alters brain chemicals.

Analyzing the Options

Next, let's analyze each option. A. Eliminates the neurotransmitter acetylcholine: This option is incorrect because while the neurotransmitter levels might be affected during ECT, the primary mechanism is not the elimination of acetylcholine. B. Increases the perception of external stimuli: This option is incorrect because although ECT may impact brain functioning in various ways, increased external stimuli perception is not the primary mechanism of how ECT relieves depression. C. Decreases levels of cortisol from the adrenal cortex: While ECT may have an effect on cortisol levels, this is not the primary mechanism of how ECT works to alleviate depression. D. Produces a seizure that temporarily alters brain chemicals: This option is correct. ECT works by inducing a controlled seizure, which helps to reset the balance of certain chemicals in the brain related to mood regulation, thereby relieving depression symptoms.

Final Answer

The appropriate response for the nurse to give the client regarding how electroconvulsive therapy helps relieve depression is: D. Produces a seizure that temporarily alters brain chemicals.
