Abstract: Objective To explore the effect of using scenario simulation to train the emergency response ability of junior nurses. Methods Eight emergency skills were selected based on the textbook of 《Nursing Emergency Plan and Safety》 and the frequency of cerebral diseases. Then eight scenario simulation cases were developed. Twenty-one junior nurses were trained by the 8 cases. Results It was showed that scores of all dimensions of nurses' emergency response ability were significantly higher than those before the training（t=8.797,P<0.05）. Conclusion Scenario simulation can effectively improve the emergency response ability of junior nurses.
