A nurse is reviewing treatment options for a client who has functional neurological symptom disorder. Which of the following treatments should the nurse identify as being most effective for this disorder?

A. Systematic desensitization. This therapeutic approach is primarily used for anxiety disorders and phobias, not specifically for functional neurological symptom disorder. It may not directly address the complexities of the symptoms associated with this disorder. B. Daily benzodiazepines to prevent new symptoms. Benzodiazepines are generally not the first-line treatment for functional neurological symptom disorder. While they may provide short-term relief for anxiety, they do not address the underlying issues related to functional symptoms and can lead to dependency. C. Daily physical therapy. While physical therapy can be a component of treatment for functional neurological symptom disorder, focusing solely on physical therapy may not address the psychological factors that contribute to the disorder. D. A combination of medication and psychotherapy. This approach is recognized as the most effective treatment for functional neurological symptom disorder. Psychotherapy, particularly cognitive-behavioral therapy (CBT), can help address the psychological aspects of the disorder, while medication may be used to manage comorbid conditions such as anxiety or depression. This combination provides a comprehensive treatment strategy.
