Final answer:
A nurse manager should capitalize on the influence of informal leaders by encouraging their participation in decision-making and recognizing their contributions to improving team dynamics and morale.
Step-by-step explanation:
In working with informal leaders, a nurse manager should employ strategies that promote a positive and collaborative work environment. Encouraging their influence within the team can be beneficial, as informal leaders often have significant sway over their peers' attitudes and behaviors.
This can be done by recognizing their contributions, seeking their input on team initiatives, and involving them in decision-making processes. Ignoring or isolating them, on the other hand, can lead to decreased morale and productivity. Discouraging team collaboration would contravene the very nature of a healthy work environment and is not a recommended strategy.
