Model interview
Full transcript
- Doctor
Mr. Choi, I'm Dr. Kim. You look tired, so while we check your vital signs, tell me what has changed.
- Patient
For about three weeks I've been incredibly thirsty, going to the bathroom all the time, and losing weight even though I'm always hungry.
- Doctor
How quickly have those symptoms been progressing?
- Patient
They've become much worse over the last week. I feel drained and weak now.
- Doctor
About how much are you drinking in a day?
- Patient
Five or six liters of water. My mouth still feels dry.
- Doctor
How often are you urinating during the day and overnight?
- Patient
About every hour, and I wake up four or five times a night.
- Doctor
How much weight have you lost?
- Patient
Eight kilograms in three weeks. I wasn't trying to lose any.
- Doctor
What has happened to your appetite?
- Patient
It's huge. I eat full meals and feel hungry again soon afterward.
- Doctor
Have you had nausea, vomiting, or abdominal pain?
- Patient
No.
- Doctor
Has your breathing become unusually deep or fast?
- Patient
No, my breathing feels normal.
- Doctor
Have you felt confused, unusually drowsy, or close to fainting?
- Patient
No. I'm exhausted, but I'm thinking clearly and haven't fainted.
- Doctor
Any recent fever, infection, or blurred vision?
- Patient
No fever or infection. My vision gets a little blurry when I'm very tired.
- Doctor
Have you ever had a high blood sugar reading or another major health problem?
- Patient
No. I've always been healthy.
- Doctor
Does diabetes run in your family?
- Patient
My grandfather developed type 2 diabetes when he was older. No one else that I know of.
- Doctor
Do you take any prescription medicine, over-the-counter product, supplement, or steroid?
- Patient
No, nothing.
- Doctor
Do you have any medication allergies?
- Patient
None that I know of.
- Doctor
How is this affecting college, and what worries you most about what might be happening?
- Patient
I can't stay awake in class, and I keep leaving lectures to urinate. I'm worried it's diabetes, and I'm scared that would mean injections every day.
- Doctor
Let me check that I have this right. Over three weeks you have developed severe thirst, hourly urination including four or five times overnight, increased hunger, fatigue, and an unplanned 8-kilogram weight loss. The symptoms are worsening, but you currently report no vomiting, abdominal pain, unusual breathing, confusion, or fainting. Is that correct, and is there anything else you want to add?
- Patient
That's correct. I mainly want the tests done and to know what happens next.
- Doctor
These symptoms need prompt assessment today. We'll check your blood sugar and ketones now and do further blood and urine tests as indicated. If you become confused, start vomiting, develop abdominal pain, or breathe deeply and rapidly, we will escalate care immediately. Once we have the results, we'll explain them and discuss any treatment with you rather than assuming what you will need.
- Patient
Thank you. That helps with the fear.
