Final answer:
The approach used for introducing computerized charting and providing orientation in nursing is a normative-reeducative strategy, involving change through social norms and peer influence.
Step-by-step explanation:
The introduction of computerized charting in a hospital and the subsequent orientation provided by a team of nurses educated in nursing informatics is an example of a normative-reeducative strategy. This approach relies on the idea that change is most effectively implemented through social norms and peer influence. In a normative-reeducative strategy, individuals change their behavior based on new knowledge and the influence of key individuals within their social system who are already utilizing the new practices.
