"It Is Difficult to Always Be an Antagonist": Ethical, Professional, and Moral Dilemmas as Potentially Psychologically Traumatic Events among Nurses in Canada.

Nurses are exposed to PPTEs at work, but little is known about factors that can aggravate PPTE exposure in the field, impact the mental wellness of nurses, and even shape patient care. We discuss the implications of PPTE involving moral, professional, and ethical dilemmas (i.e., potentially morally injurious events), and provide recommendations for nursing policy and practice.
