What is the purpose of the voicemail message?

Good morning, this is Nurse Campbell from the fourth floor calling for Mr. Stevens in the X-ray department. My patient, Alex Lambert, had X-ray taken last week for his ankle. It’s been five days and I’m waiting for the test results to be delivered to me. I need the results to see how far along his ankle is healing. Could you please contact me to tell me if they have been sent yet? You can reach me on my direct line, which is 514-566-5564. Thank you.
