The findings revealed that total knowledge regarding nursing care standards of colostomy was at unsatisfactory level. The reasons might be due to the background of the subjects. The majority of the nurses had gained a diploma in nursing (88.5%). Only (11.5%) of nurses with Bachelor of Science in Nursing. Previous study found that education has a significant impact on the knowledge and competencies of the nurse clinician, as it does for all health care providers. Nurses with Bachelor of Science in Nursing (BSN) degrees are well prepared to meet the demands placed on today's nurse. BSN nurses are prized for their skills in critical thinking, leadership, case management, and health promotion, and for their ability to prac-tice across a variety of inpatient and outpatient settings [21].
