OBJECTIVE: The aim of this paper was to show a different attitude towards death and pain, with the primary distinction being the existence or absence of religious belief. The paper also presents the tools by which the nurse can positively influence feelings related to death and thus help the patient regardless of which group of subjects they belong to. METHODS: The study was conducted at the Department of Pulmonology with long-term treatment and palliative care at the General Hospital “Dr. Ivo Pedišić “Sisak, and the subjects were hospitalized there for the period of 5 months during which the trial was conducted. The total number of respondents was 100. Data for the graduation thesis were collected by conducting a 5-part questionnaire. The first part of the questionnaire examined demographic data, the second part religious orientation, the third part the impact of religious commitment on pain management, and the fourth part the understanding of death, also depending on the influence of religious commitment. The fifth part of the questionnaire examined the impact of the nurse's approach on pain management and understanding of death in palliative patients. RESULTS: The results confirmed the initial hypothesis that persons with religious beliefs are more likely to tolerate the pain and death than those who lack them. Religious respondents see the higher meaning of suffering from the disease and the inevitability of death, making it easier for them to endure pain and understand death. The study also showed that respondents who declare themselves to be non-religious need more comfort from the nurse than those who declare themselves as religious. CONCLUSION: This study showed that the existence or absence of a religious commitment is closely related to pain tolerance and understanding of death in patients.
