Which of Gardner's tasks of leadership is demonstrated by a nurse who takes care of themselves to better care for their staff?

The task of leadership that is demonstrated by a nurse taking care of themselves to better care for their staff is "Renewing." This concept emphasizes the importance of self-care and personal well-being as foundational aspects of effective leadership. When leaders prioritize their health, they are more energized, focused, and capable of providing support and guidance to their team. Renewing illustrates the idea that leaders must replenish their own resources—physically, emotionally, and mentally—so they can lead with clarity and compassion. By caring for themselves, the nurse enhances their ability to foster a positive work environment, ultimately benefiting the entire team and improving patient care.

The other choices reflect different aspects of leadership but do not specifically address the concept of self-care as a critical component of leading effectively. For instance, enabling often involves providing the necessary tools and resources for team members to succeed, while coaching focuses on guiding individual team members in their development. Empowering refers to enabling individuals to take charge of their own work and make decisions, which is vital but does not specifically relate to the self-care aspect highlighted in the question.
