From CNN:
1. Say: "My name is Mary Smith, my date of birth is October 21, 1965, and I'm here for an appendectomy."
2. Say: "Please check my ID bracelet."
3. Say: "Please look in my chart and tell me what procedure I'm having."
4. Say: "I want to mark up my surgical site with the surgeon present."
5. Be impolite.
