One reason for the existence of Poison Control Centers is to-
a.Assist doctors and nurses only, not to give advice to laypersons.
b.Help call takers send the right kind of EMS personnel and equipment to the scene of a potential poisoning.
c.Give advice primarily to hospital emergency physicians about the proper care or treatment for poisoning.
d.Prevent the overburdening of the EMS system with a poisoning that can be cared for without the help of EMS personnel.
