Final answer:
A nurse-manager best demonstrates transformational leadership by inspiring staff through professional development projects, caring for their emotional welfare, and by being a charismatic role model and considerate leader.
Step-by-step explanation:
Action by the nurse-manager in a health organization that best demonstrates transformational leadership involves inspiring and motivating staff to not only fulfill organizational goals but also go beyond their self-interest for the good of the team and the patients they serve. This can be exemplified by initiating a project that supports the personal and professional development of the nursing staff, acknowledging their challenges, and facilitating a culture that allows them to provide input and feedback on care practices and policies. This may include implementing a comprehensive staff support program that addresses both the clients' needs and the emotional and psychological welfare of the caregivers, much like the curriculum at the Healthy Start Southeast Chicago Program. This approach aligns with the characteristics of transformational leadership as described by Bass, Avolio, & Atwater, which involves being a charismatic role model, providing inspirational motivation, stimulating staff intellectually, and being considerate of their individual needs.
