Final answer:
The most appropriate situation for a nurse to collaborate with a spiritual care provider is when a patient expresses a desire for spiritual comfort, such as the need to confess sins before dying (option D). This is part of providing comprehensive hospice care that supports the spiritual aspects of a patient's end-of-life experience. Option D is correct.
Step-by-step explanation:
A hospice's interdisciplinary team typically includes spiritual care providers who are trained to support patients and families through the spiritual and emotional aspects of dying. When a patient expresses a desire for spiritual rituals or support, as in option D, it becomes essential for the nurse to facilitate this aspect of care by collaborating with a spiritual care professional, ensuring that the patient's holistic needs are met during this critical time.
