A nurse is assisting in the care for a client who is exhibiting a depressed mood one week before the start of their menstrual cycle. When collecting data, the nurse should identify that the client is exhibiting manifestations consistent with which of the following disorders?

A. Cognitive behavioral therapy. Cognitive behavioral therapy (CBT) is a noninvasive treatment that helps individuals with depression by identifying and modifying negative thought patterns and behaviors. It is widely used and effective in improving mood, coping skills, and overall mental well-being.
B. Vagal nerve stimulation. Vagal nerve stimulation (VNS) is an invasive procedure that involves implanting a device to stimulate the vagus nerve. It is used for treatment-resistant depression and is not considered a first-line, noninvasive option.
C. Electroconvulsive therapy. Electroconvulsive therapy (ECT) is a medical procedure that involves electrical stimulation of the brain under anesthesia. Although effective for severe depression, it is invasive and typically reserved for cases that do not respond to medication or therapy.
D. Deep-brain stimulation. Deep-brain stimulation (DBS) involves surgically implanting electrodes in specific brain regions to regulate mood-related neural activity. It is an invasive treatment used in research or for severe, treatment-resistant depression.

A. Inappropriate guilt is a common symptom of depression, but it does not involve false beliefs about being targeted. Clients with major depressive disorder may feel excessive guilt, but this differs from the fixed, false beliefs seen in delusions.
B. Mania is characterized by elevated mood, impulsivity, and hyperactivity rather than paranoid thoughts. While manic episodes may include grandiose delusions, the belief that a government agency is attempting to capture the client aligns more with persecutory delusions.
C. Delusions are fixed, false beliefs that persist despite evidence to the contrary. The client’s statement suggests a persecutory delusion, which is commonly seen in psychotic disorders, including severe depression with psychotic features.
D. Confusion involves disorganized thinking, memory impairment, or difficulty understanding surroundings, often seen in delirium or cognitive disorders. While delusions can contribute to disorganized thoughts, they are distinct from general confusion.
