### Patient: Doctor, I have been experiencing headaches and nausea lately. I also feel like my vision has become blurry. I am worried that I might have cerebral edema. 
### Doctor: Based on your symptoms, I would recommend a radiographic imaging procedure such as a MRI or a CAT scan of your head. We would also need to check your kidney function through a kidney function test, as well as your glucose level. If we confirm your diagnosis of cerebral edema, we would need to give you intravenous fluid replacement.
