I'm working on a health & medical discussion question and need an explanation and answer to help me learn.

Barbara Jones and her daughter, Patricia has been a patient of Dr. Young for many years. Patricia is currently in college and is in need of her medical records. Patricia has asked her mom, Barbara to pick up a copy of her medical records. Is it acceptable for Dr. Young's medical practice to release a copy Patricia's medical records to her mom? If so, why? If not, why?
