Introduction: The use of ultrasound in nursing practice is constantly expanding with applications in numerous clinical settings, for supporting diagnostic assessments, procedural guidance, monitoring, and verification of device placement. However, the patterns of employment, the skills required, and the impact on care outcomes are heterogeneous. Objective: To map the clinical applications, outcomes, training requirements, and main barriers and facilitators to the implementation of nurse-performed ultrasound in different health care settings. Methods: A scoping review was conducted according to the Arksey and O’Malley framework, integrated with the Joanna Briggs Institute indications, and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. The research was conducted in PubMed, Scopus, Web of Science, and Google Scholar without time limits. Studies describing the use of ultrasound by nurses in any clinical setting were included. The data were extracted using a standardized form and narratively synthesized into thematic domains. Results: Twelve studies met the inclusion criteria, including randomized trials, observational, qualitative studies, and reviews. Ultrasonography was used for (1) diagnostic evaluations, including abdominal aorta, bladder volume, and lung; (2) procedural guidance, mainly for peripheral venous access and catheter tip localization; (3) clinical monitoring, such as hemodynamic evaluation and enteral feeding management; (4) verification of device placement. Studies reported improvements in first-time success, suggested fewer procedural complications, increased diagnostic accuracy, and increased patient satisfaction. Among the barriers are insufficient training, limited availability of devices, and cultural resistance. Facilitators include structured training programs, institutional support, and shared protocols. Conclusions: Ultrasound used by nurses shows a reported clinical impact, improving safety, accuracy, and continuity of care. Wider adoptability requires standardized training, access to technologies, and integration into interprofessional paths. Future studies should evaluate long-term outcomes and applications in territorial and home settings.
