Final answer:
The nurse should prepare the client for the end of the therapeutic relationship starting from the initial meeting. This readies the client for eventual independence and helps manage potential separation anxiety.
Step-by-step explanation:
The nurse should begin preparing the client for the termination of the therapeutic relationship during the initial meeting. This is an integral part of the therapeutic relationship known as the termination phase, which should be introduced from the onset to help the client understand that the relationship is professional and time-limited. Early preparation for termination can ease any potential anxiety about the end of the relationship and reinforce the goal of helping the client become independent.
