Data was collected by a three-part questionnaire and analyzed by t-test and ANOVA using SPSS-PC (v. 16). &nbsp; Results: The mean and standard deviation of the most frequent medication errors were respectively related to the rapid infusion of the medicines that nurses should have injected slowly (0.47&plusmn;0.92), non- adherence to the necessary steps related to the medicines requiring special attention (0.46&plusmn;0.82), and no dilution of medicines that must be diluted (0.37&plusmn;0.72). Also the most common causes of medication errors were reported as fatigue related to heavy workload (99.2%), many ill patients (80.3%) and distorted and unreadable physician's orders (79.5%). Significant relationships were found between the occurrence of medication errors and type of employment and shift work (p<0.05). &nbsp; Conclusion: Regarding the types and causes of medication errors from nurses&rsquo; perspective, approaches to increase nursing staff, using electronic medical kardexes, and retraining courses on pharmacologic information would be helpful.
