Correct Answer: D

Rationale: A therapeutic milieu is characterized by focusing on the needs and goals of the patients. By establishing specific patient-centered goals that are agreed upon mutually by the patient and the staff, it ensures that the care provided is individualized and tailored to the patient's needs. This approach fosters a collaborative and empowering environment where the patient feels heard and supported in their recovery journey. It also promotes a sense of ownership and accountability for both the patient and the staff in working towards these goals together. In contrast, rigid adherence to timelines and unit routine (option A) may not always take into account the unique needs of each patient, and relaxation of boundaries (option B) can potentially compromise the therapeutic process by blurring professional boundaries. Therefore, establishing patient-centered goals is a key component of creating a therapeutic environment on a nursing unit.
