What Gardner's task of leadership is being applied when a nurse helps a client articulate personal values?

Affirming values is the correct choice because it involves assisting individuals, such as patients, in recognizing and understanding their personal beliefs and principles. When a nurse engages with a client to help them articulate their personal values, it empowers the client to gain clarity about what is important to them. This process not only fosters self-awareness but also supports the client’s ability to make decisions aligned with their values.

In healthcare, affirming a patient's values can significantly influence their care plans and treatment choices, enhancing the therapeutic relationship and encouraging active participation in their own health management. By validating and discussing these values, the nurse nurtures trust and openness, which is essential for effective teamwork in a healthcare setting.

The other options, while relevant to aspects of healthcare and teamwork, do not specifically capture the essence of helping a client articulate their personal values. Implementing change focuses more on introducing new practices or strategies, building relationships emphasizes developing connections over time, and supporting decision-making centers on assisting clients in making informed choices based on available options rather than on their intrinsic values.
