Introduction. Chronic pancreatitis is a complex inflammatory disease characterized by progressive destruction of gland tissue, fibrosis, and disorders of exocrine and endocrine functions. Aim. The aim of the study is to present the process of nursing care of patients with chronic pancreatitis using the ICNP® terminology. Case study. The research employed the case study method and the technique of the interview, observation, analysis of medical records and measurements. The C-HOBIC data set was used to assess the patient's condition. The study was carried out at the Copernicus Hospital in Gdansk at the Department of Internal Medicine and Diabetes in May 2019 and included a 61-year-old patient hospitalized for persistent abdominal pain, nausea, vomiting and diarrhoea. Conclusions. As a result of the assessment of the patient's condition, 11 nursing diagnoses were formulated, including 6 current diagnoses reflecting the patient's physiological status (abdominal pain [10043953], nausea [10012453], vomiting [10025981], diarrhoea [10000630], hyperglycaemia [10027550] and altered blood pressure [10022954]), 1 potential diagnosis (risk for infection [10015133]), as well as 2 diagnoses concerning the patient's lifestyle (alcohol abuse [10022234] and tobacco abuse [10022247]), psychological status (anxiety [10000477]) and self-care (lack of knowledge [10000837]). The nursing care plan included diagnostic interventions related to the assessment and monitoring of the patient's status, as well as the management of symptoms and problems found in the patient, and the participation of the nurse in the therapeutic process. Interventions aimed at health education and providing mental comfort for the patient were an important part of the nursing care plan.
