Abstract
This article presents a scoping review aimed at mapping the main sources of moral distress among nursing professionals. The review was conducted according to the Arksey and O’Malley methodology, using the SPIDER framework to guide the systematic search in the BVS, PubMed, PsycArticles, Scielo, and Scopus databases. Initially, 2320 publications were identified. After the application of inclusion and exclusion criteria, 83 studies were selected for analysis in terms of their methodological characteristics, objectives, practice contexts, and various sources of moral distress identified. The analysis facilitated the grouping of these sources into specific situations, reflecting the challenges experienced by nurses under different practice settings. This review augments the knowledge of the causes of moral distress in nursing, highlighting the impact of this phenomenon on the physical and mental health of professionals, as well as on the quality of care provided.
