Which of the following is one of the nurse's primary responsibilities in end-of-life care?

While assisting caregivers with conflict resolution may be important, it is not one of the primary responsibilities of nurses in end-of-life care. This task often falls under the purview of social workers or counselors who specialize in mediation and emotional support, rather than nursing duties focused on medical care.

Although culturally competent care is important in nursing, applying a standardized approach across diverse cultures can overlook individual patient needs and preferences. End-of-life care should be tailored to respect the unique cultural values and practices of each patient and their family, making this choice less aligned with the primary focus of nursing responsibilities.

Building rapport and providing emotional support are certainly beneficial aspects of nursing care; however, befriending patients and families is not a primary responsibility. The main focus of nurses in this context is to provide professional, compassionate care and accurate medical information, rather than developing personal friendships.
