The effective use of nursing diagnoses plays an important role in improving the quality of nursing care. However, evidence regarding the extent to which nursing students use these diagnoses in clinical practice is limited. The primary purpose of this retrospective descriptive study is to examine the nursing diagnoses used by nursing students in their clinical care plans based on the Roper-Logan-Tierney Activities of Living Model. The study aims to determine the students' diagnostic trends and identify areas requiring improvement in nursing education.
