I've been doing some research on this and I can't quite find concrete
evidence for presenting. Any help would be great.

So there's a hypothetical situation: A resident gives an order for a
medicine to be prescribed, and a medical student accidentally gives a
higher dose than ordered. (Say for example too much is drawn in a
syringe or an incorrect decimal pt. on a drug order). The patient dies
from this overdose.

The ethics question is, does the student report this and admit error? 

Of course the ethics answer is yes, but in reality it would be very
easy to just say the patient died (forgot to mention, the patient was
a trauma case and could have died regardless). But the point here is
to list concrete reasons why this should be done. Obviously these
include the illegality of incorrectly marking partient's charts,
potential loss of license, etc. I have yet to find concrete examples,
however, despite researching the Journal of Medical Ethics.

Any laws or specific codes and preferably case examples would be great.
