Objective: The aim was to map, in the scientific literature, nursing care and health promotion competencies in cardiometabolic diseases in the light of the Galway Consensus.Methods: This is a scoping review carried out in accordance with the JBI recommendations, from November 2021 to January 2022, in five databases. The studies were analyzed according to the Galway Consensus competency domains: catalysing change, leadership, assessment, planning, implementation, evaluation, advocacy and partnerships.Results: A total of 85 studies were included in the review, and existing scientific production points out that nurses carry out comprehensive actions, which involve educational interventions, follow-up of nursing at home and at the health institution for individuals/families, health service management and partnership articulation to guarantee longitudinal, comprehensive, qualified and network-integrated care. The most highlighted domain was catalysing change, followed by assessment, planning, implementation, partnerships, advocacy and evaluation. Care such as health education, guidance on healthy eating habits, physical activity, weight reduction, smoking cessation and foot care/shoe use stood out, in addition to guidance on drug treatment, counseling, care/support for the family, home visits, follow-up by telephone and referral to a nutritionist and other professionals.Conclusions: It is necessary to strengthen competencies such as leadership and health advocacy in health promoting nurses, considering that few studies related to such themes were identified.
