Abstract: Moral distress occurs when the doctor’s perception of ethically suitable action cannot be implemented due to situational constrains at health care settings (Ferrell, 2006). Moral distress can also be defined as emotional stress of the health care worker due to ethically conflicting situations (Kälvemark, Höglund, Hansson, Westerholm, & Arnetz, 2004).The study was conducted in the National Cancer Institute Maharagama (NCIM), in Sri Lanka.
