Code for Nurses, a set of guidelines for carrying out nursing responsibilities adopted by the American Nurses Association (ANA) in 1985. In 1994, the American Nurses Association determined that these guidelines were nonnegotiable and determined that each nurse had an obligation to adhere to the Code, and in 2001 a completely revised version of the Code of Ethics for Nurses was accepted by the ANA. The code was revised again in 2015.
