Hello, this is SimCell
May I speak with (POC)?
This is an Exercise
I am calling from CHLA to give you your pediatric patient assignments
You will receive (12, 7, 5) pediatric patients
Are you ready?
Your patients are numbers (1,2,3, etc.) on the list
Would you like to confirm and relay to me your assigned patients?
