Introduction. Crohn's disease (CD) affects the whole gastrointestinal tract. The essence of the disease is an inflammation which may affect each segment of the gastrointestinal tract. The first symptoms appear mostly in young people between 15 and 25 years of age. Apart from the gastrointestinal tract symptoms, patients may develop symptoms relating to other systems and organs. Aim. The aim of this study was to formulate a plan of nursing care of a patient with Crohn's disease with the use of the International Classification for Nursing Practice. Material and methods. The research is based on an individual case study and the analysis of literature. The study was conducted in December 2015 at the Department of Gastroenterology and Hepatology, the University Clinical Centre of Medical University of Gdansk. Written consent of the patient was obtained for the study. Results. In the process of providing nursing care to the patient, we used phrases that describe "ready" diagnoses and nursing interventions contained in the International Classification for Nursing Practice ICNP®. The plan of care includes the following nursing diagnoses: abdominal pain, impaired defecation, impaired skin integrity, nausea, lack of appetite, risk for being underweight, anxiety, lack of knowledge of disease, lack of knowledge of dietary regime, fatigue. Conclusions. The proposed plan of nursing care for a patient with Crohn's disease based on the ICNP reference terminology fully reflects the key problems of the patient and the extent of interventions undertaken by nurses.

Key words: nursing diagnosis, classification, nursing care, Crohn's disease.
