Diabetes mellitus must be carefully managed and cared for to reduce complications and enhance quality of life. Nurses are essential to the treatment of people with diabetes, so they must have up- to-date knowledge and expertise in diabetic education. The significance of diabetic education for nurses, its effect on patient outcomes, and techniques for boosting nurses' competency in diabetes care are critical to positive patient outcomes and are all explored in this academic research. The results suggest a notable disparity between the participants' knowledge ratings before and after the intervention, confirming that all 13 participants benefited from the diabetic self-management education program.
