A philosophic approach to analysis reveals that the concept of right(s), with 10 identified attributes, is subject to ambiguous and inconsistent interpretation. This lack of clarity in interpretation contributes to controversy when rights are used for resolution of ethical conflict. Characteristics of rights contributing to their misinterpretation include their origins and the diverse ranges of their intended scope. Rights may be self-evident or derived from a contract. Although they are inalienable, they may not be operational. Furthermore, having a right does not entail having the power to attain it. This philosophic analysis yields a theoretic definition intended to guide nurses in rational interpretation and use of rights in their practices.
