Which statement about ethical referrals is correct?

The correct choice emphasizes the importance of communication among all relevant parties in the referral process. Ethical referrals involve not only the act of transferring a client to another professional but also ensuring that everyone involved is kept informed and on the same page. This practice is crucial for maintaining trust and transparency in the therapeutic relationship.

Informing relevant parties about the referral helps coordinate care, supports continuity for the client, and can enhance treatment outcomes. It ensures that all professionals are aware of the client's situation and can provide cohesive support. Engaging clients in the referral process is also essential, as it empowers them and respects their autonomy, which aligns with ethical standards in practice.

The other options do not align with ethical practices, as they suggest either neglecting the client's involvement or failing to inform other necessary parties, which could undermine the quality of care and the therapeutic relationship.
