Problem: Describe the rationale for selecting an IS model to guide your proposed project (managing post-op nausea vomiting in pediatric patients). Identify and evaluate potential IS models for use. The T-CaST tool in your readings may be very helpful in completing this assignment. Compare and contrast how the models relate to your proposed projects. Write about how the various models work as guides for a project and which one might be useful for your particular project. The outcome of the discussion is a clear statement of model choice, with rationale.
