Mentally and Physically handicapped class III

I tried last night to think of what my patient might need since she has the functioning capacity of a 4-year-old. I didn't know what to think but decided that it would be fine to talk to her like she was my 4-year-old. She was very cooperative. I was able to test her blood sugars to pass off a PE. When I did start to scale her she had a wall of calculus just subgingivally so I am sure that my probe depths are inacurate. She is very hard to clean due to the tenasious calculus. I got to use my orange ultrasonic for the first time.
