Final answer:
Nurses should be involved in public policy because they are closest to the frontline of patient care, and can use their firsthand experience to shape and improve healthcare systems and policies.
Step-by-step explanation:
The importance of nurses being involved in public policy is primarily because nurses are closest to the front line of patient care. This proximity to patients gives nurses a unique perspective on the impact of healthcare legislation and the practical needs of healthcare delivery. Involved nurses can leverage their frontline experience to lead improvements in the healthcare system, ensuring that healthcare policies are aligned with the real needs of patients. Moreover, their voice in legislative matters can help shape policies that make healthcare more affordable and accessible, acknowledging the expertise gained from their critical thinking skills and understanding of the healthcare environment.
