This article delineates a nursing experience of utilizing the Swanson's caring theory on a terminal cancer patient and the caregiver. The nursing period lasted from July 25th to August 3rd, 2014. The author collected and analyzed data on the patient's physiology, mental acuity, social nature, and spirituality through observation and communication. The author identified pain and hopeless due to lack of prognosis-control as the primary problems of this patient, and both caregiver role strain and anticipatory grieving contributed the suffering of caregiver. Utilizing the Swanson's caring theory, "knowing and being with" may encourage patient and caregiver to talk through their current difficulty situation and feeling. By "doing for and enabling", the author provided aromatherapy massage, hot fomentation, and music therapy for pain management. Besides, introduction of nursing guide and relaxing technique may alleviate caregiving difficulty and stress. Life review with family members through photo and letter writing can "sustain belief", generate and maintain a positive attitude at the moment of death. Patient focused on what he has accomplished in his life span and expressed immense gratitude to each other. The author wishes to share this nursing experience with all nurses to encourage clinical practice with caring theory. The author also suggests more case study and caring technique program may be beneficial in taking care of the similar patients in the future in term of palliative and spiritual care.
