Abstract: Nursing practice necessitates the application of knowledge, skills, and values in various combinations, all of which have undergone significant changes in recent decades. There is a greater emphasis on interprofessional collaboration, as well as possible new and more independent roles for nurses, especially in the emergency units. Therefore, the study aimed to assess the clinical competence of emergency nurses based on a self-assessment tool. Methods: a descriptive study design was applied to 87 nurses enrolled in the emergency units at King Khaled and King Salman Specialist Hospital. A demographic data sheet and clinical competency questionnaire were used for collecting data. A descriptive statistic: frequency and percentage were carried out. Results reveal that the majority of emergency nurses have a high level of clinical competency scores.
