Final answer:
The nurse's activities in providing comfort and arranging for the Sacrament of the Sick for a terminally ill patient in hospice care align with the principles of social gerontology and thanatology, embodying a holistic care approach.
Step-by-step explanation:
The nurse's care of the terminally ill patient under hospice care falls under the holistic care approach which is consistent with the principles of social gerontology and thanatology. Hospice care focuses on providing comfort and supporting the quality of life until the end, recognizing that for terminally ill individuals, cure-oriented treatments are no longer beneficial. The nurse's actions reflect a commitment to comfort care, fulfilling the patient's medical, emotional, and spiritual needs, which is integral to hospice care. This includes attending to daily needs, arranging for a religious sacrament according to the patient's beliefs, and supporting the family during this challenging time.
