Final answer:
Joan is demonstrating reflective practice by understanding her reactions to a new graduate and acknowledging that he needs guidance, rather than perceiving him as a threat.
Step-by-step explanation:
Joan, the nursing unit manager, is demonstrating reflective practice by recognizing her discomfort with Thomas, a new graduate, as a reaction to feeling threatened rather than a true assessment of his intentions. After discussing with others and reflecting on the situation, she realizes that Thomas is not challenging her leadership but is attempting to establish his own role in the unit. Joan recognizes the need for her to offer guidance, coaching, and affirmation to Thomas to foster a positive working relationship.
