Answer:
Although historically nurses have been taken as the bedside caretakers of patients, and the medicine distributors, the truth is that nurses, given their level of involvement in direct care, have become enabled to do much more than that.
In public policy creation, nurses also play a vital role, and they have a lot to give in the field of politics, precisely because they not only have professional formation, but also extensive research knowledge and also practice. This experience, and the extended education that nurses undergo, allows them to be able to intervene in the arena of politics, especially when it comes to public policy formation, on the field of healthcare.
For example, a nurse is very capable of becoming a great administrator, and even a legislator. So she could find herself in the position of secretary of health, or as a senator, or representative, and she would be able to promote public policy that favors other healthcare professionals in terms of working hours, compensation, working environment, working conditions, because she has experienced all those, but also because she has studied and prepared herself to know about all this.
This, and many other reasons, is why nurses can become very active in legislation formation and public policy formation.
