The Owner of a Day Care Center for Adults with Alzheimer's

The owner of a day care center for adults with Alzheimer's disease calls you to ask about an AED at her facility. Specifically, she asks if she will need a physician to oversee the AED program. Your reply should be:

A) "If you intend to use the AED on anyone under the age of 50 years, a medical director will be needed."
B) "A medical director is only needed if you are going to bill insurance companies for the provision of care; if you are not, a medical director is not needed."
C) "You will need to have a physician medical director since the AED can only be used with his or her permission under his or her license."
D) "If you get a semi-automated AED, you will need a physician medical director. Since fully automated AEDs are easier to use, a medical director is not needed."
