The study determined the significance of how nursing students comply with their clinical instructors’ way of delivering the 11 core nursing competencies in administering medications. The study used descriptive research method to describe the behavior or type of subject and to look for any specific relationships or to correlate two or more variables. It also involves observing and describing the behavior of a subject without influencing it in any way. A validated survey questionnaire was administered to 28 respondents chosen through stratified random sampling. Results showed that the most applied core nursing competency in administering medications is having legal responsibility while professional and personal development is the least applied. The study recommended that the department should find various ways to encourage their students to participate actively in the activities related to them and evaluate the existing curriculum and develop a new one if necessary. The nursing students, on the other hand, should develop core knowledge, attitudes and skills in caring for the parents, and extend the study by trying other interventions for the positive compliance.
