Answer:
If the patient is over 18, their religious beliefs should be allowed to override the best interest.
Step-by-step explanation:
If the patient is a child, their best interest should always come first. There is no guarantee that the child will even follow in the parents religious beliefs. The best interest of a child should always come first.
If the person is over 18, they should be allowed to make their own decisions because they can understand the risks associated with their choice.
