Medications involving many health disciplines are perhaps the most important process for the nursing profession. In addition to the ethical and legal responsibilities of the students during this process, it is also vital to determine the mistakes that can lead to serious problems for the patient and to do the studies to reduce them. With this study, it is aimed to detect such mistakes of the students who will perform the nursing profession and to draw attention to this issue to take the necessary precautions. The sample of this study, which was made in the descriptive type, was the 3rd and 4th grade students (n = 129) of the Health School of Amasya University who accepted to answer the questionnaire. The questionnaire form obtained by searching the existing literature was used as data collection tool. When the results were evaluated statistically; it was seen that during the oral medication, the mistakes such as not waiting beside the patient, dropping the oral medicine beside the patient and applying a medicine prepared by someone else to the patient were done at a high rate. Among these faults, it has been determined that the least ones are the application of the medicine in the wrong way and the application of the wrong medicine or the wrong patient. As a result, in terms of preventing such medication errors, it was seen as important; - to ensure that students are given more rigorous inspections by their instructors during medications in the lessons they have seen in their schools and in clinical practice, - to ensure that the proportion of the number of lecturers giving such courses, the number of students and the fields practiced are balanced, and - to ensure that the studies are carried out for the preparation of appropriate course materials for nursing students to enhance their knowledge of medicine and clinics.
