Final answer:
The barrier to therapeutic communication in this scenario is offering advice.
Step-by-step explanation:
The correct answer for the barrier to therapeutic communication in this scenario is A. Offering advice. Providing advice is a barrier because it can undermine the client's autonomy and hinder their ability to express themselves and make their own decisions. Therapeutic communication requires the nurse to actively listen, reflect meaning, and provide information when appropriate, but offering advice can interfere with the therapeutic process.
