(1) Background: The aim of this study was to review the scope of the existing scientific literature on creating safe and inclusive healthcare environments for transgender people and provide an overview of the resources and nursing skills required to do so. (2) Methods: With the research question in mind, an exploratory search of six databases was conducted to identify all relevant primary studies. After screening and selection of articles based on the inclusion and exclusion criteria, a total of 41 articles were included and reviewed. (3) Results: The results were classified under four headings: the training of health professionals, the creation of safe spaces, the nurse as facilitator, and best care practice. Most of the evidence indicates that it is essential for nurses and other healthcare staff to be trained in specific skills to provide comprehensive, high-quality care to transgender people; however, there is a lack of material and human resources to do so. (4) Conclusions: The trans-inclusive care competent nurse should use neutral language that respects the person's preferred name and pronouns in a safe healthcare environment that offers and ensures warmth, respect, and inclusivity in the care provided. This study was registered with the Open Science Framework (OSF) on 9 January 2024 (osf.io/rpj6a).
