 Realistic simulation is an effective teaching strategy for the acquisition and retention of knowledge and increased self-confidence of students, which contribute to safety in performing nursing actions.Considering the need to adopt safe practices in health since professional training, there are deficiencies in health teaching and weaknesses in the acquisition of practical skills guided by safety principles and critical clinical reasoning. The purpose is to compare the use of high fidelity simulation with traditional education as innovative method in the process of teaching and learning. This is a prospective, randomized, controlled and single-blind study, of pre-test and post-test experimental type, with application of high fidelity simulation in the theme of patient safety in administration of parenteral drugs.
