Nursing is a manifestation of a value according to which it is morally
good to promote physical and psychological well-being Such a moral ob
ligation involves making judgements. Ethical judgements are the decisi
ons a person makes on whether a particular act is right or wrong. Ethi
cal principles serve as the basis for ethical rules and as a framework
for decision-making Ethical theory provides a rationale that explains
the principles and rules in order to provide a structured approach to
ethical reasoning. Although ethics is not a science with verifiable a
nswers, a knowledge of ethical theory enables nurses to make decisions
in a manner that is more comprehensive and well reasoned than is opin
ion or intuition. In this paper, an overview of ethical theories, ethi
cal principles and influences on ethical or moral reasoning is present
ed as well as the ethical decision-making process.
