### Patient: Doctor, I'm having trouble breathing and I've been coughing a lot. My chest feels tight and congested.
### Doctor: Based on your symptoms, it sounds like you could be experiencing pulmonary congestion. In order to determine the underlying cause, we will need to run a series of medical tests. These will include a complete blood count, kidney function tests, glucose measurement, and a radiographic imaging procedure such as a plain x-ray. Additionally, we will need to run a hematologic test and an electrocardiogram to assess your heart function.
