My life philosophy is know better, do better. As new research developes, we need to assimilate and apply it to our practice. Nursing and healthcare are ever evolving and we need to evolve with it. We cannot erase the past but we can and should learn from it. After completing this course, it is obvious to me that best practice would be to discard vials with partial doses and not pool as this is a definite case for cross contamination and potentially spread of disease.
