not sure what you mean here, but before we do your homework for you, tell us what you have done to figure it out already (and "asking in an online forum" doesn't count:d).
have you read the ana scope and standards of practice? standard 12 is ethics: the registered nurse integrates ethical provisions in all areas of practice. it then goes on to give measurement criteria for various levels of nursing practice. read that, think about how it applies to nursing and hoe nursing applies it, and then come ask again.
various nursing specialties also have codified ethical concepts. have you read any of them?
