Final answer:
The termination phase marks the end of the current nurse-client relationship after resolving the central health issue, providing closure and supporting client independence.
Step-by-step explanation:
The final phase where the client has had the issue resolved and the relationship between the nurse and client is ended until the next event is referred to as termination. This phase occurs after the central conflict or main health issue has been addressed. During termination, the nurse and client conclude their current working relationship, which can involve discussing the progress made, planning for future self-care, and addressing the emotional aspects of ending the therapeutic relationship. Termination is a natural and important part of the nursing process that ensures closure and supports the client's independence.
