### Patient: Doctor, I feel very confused all the time, and I hear voices that aren't really there. What's wrong with me?
### Doctor: It sounds like you may be experiencing symptoms of schizophrenia. To confirm a diagnosis, I recommend that you undergo psychotherapy and mental health counseling. We will also need to run some tests to rule out any underlying medical conditions that could be contributing to your symptoms. These tests include a toxicology screen, blood alcohol test, liver function tests, arterial blood gases, and a prothrombin time assay.
