A client is admitted to a psychiatric unit for treatment of a psychotic disorder. The client is at the locked exit door and is shouting. "Let me out! There's nothing wrong with me! I don't belong here!" The nurse identifies this behavior as which defense mechanism?

A. Postpartum depression occurs after childbirth and is usually treated with a combination of psychotherapy, antidepressant medication, and support. While light therapy might have some benefits for mood disorders, it is not the primary treatment for postpartum depression.
B. Seasonal affective disorder is a type of depression that typically occurs at certain times of the year, usually in the winter months when there is less natural sunlight. Phototherapy, or light therapy, is considered an effective treatment for SAD as it helps to mimic natural sunlight and improve mood by influencing circadian rhythms and serotonin levels.
C. While light therapy can have effects on mood, it is generally not used as a primary treatment for bipolar disorder. Bipolar disorder is often managed with mood stabilizers and other medications to prevent mood swings.
D. While light therapy can be beneficial for some types of depression, it is not typically the first-line treatment for moderate depression. Moderate depression is usually treated with antidepressants, psychotherapy, or a combination of both.

A. Providing companionship can help reduce feelings of isolation and agitation that may be exacerbated by sundown syndrome. Presence and interaction with a supportive person can provide comfort, reassurance, and a sense of security, which may help manage anxiety and agitation during the late hours.
B. Engaging in stimulating activities in the late afternoon or evening can sometimes worsen symptoms of sundown syndrome. Instead, activities should be calming and relaxing as excessive stimulation can
increase agitation and confusion. It’s better to plan stimulating activities earlier in the day.
C. Maintaining a familiar routine helps provide structure and predictability, which can be comforting for individuals with dementia. Consistent routines can help reduce confusion and anxiety, especially during the times when sundown syndrome symptoms are most pronounced.
D. While reminding the client about bedtime may seem like a good strategy, it can sometimes lead to frustration or increased agitation if the client is not ready for sleep or is confused. It is generally more effective to create a calming environment and use soothing routines rather than directly reminding the client of bedtime.
E. Reducing environmental stimulation, such as minimizing noise, bright lights, and other distractions, can help create a calm and peaceful environment. This approach can help prevent overstimulation, which is known to exacerbate sundown syndrome symptoms.
