Historic Leadership: One Courageous School Nurse's Heroic Journey-Part 3.

School nursing practice establishes itself in the midst of both education and nursing philosophies, ethics, standards, laws, and regulations. Treading these two worlds is difficult at times and requires that a school nurse possess a strong foundational knowledge base, seek professional collaboration, and navigate conflicting professional demands in order to promote student and public safety. This article is Part 3 of a four-part series that recounts the inspiring story of a school nurse, Ellen Johnsen, who did just that back in the 1980s in Broken Arrow, Oklahoma. Part 3 describes the publication of the Attorney General's opinion validating the illegality of the school district's medication administration policy, the lawsuit Ellen brought against the Broken Arrow Public Schools, and the appeal of the final decision in that lawsuit. The purpose of this series is to enhance understanding of the legal parameters governing school nurse practice, provide examples of ethical decision making, and review the challenges associated with serving as a leader.
