Abstract The theoretical part of the thesis entitled The Use of NIC and NOC Classifications at Patients with the Total Hip Arthroplasty deals with the problem of the total hip replacement, educating patients before surgery and the regime which must be observed by the patient during the hospitalization and when being discharged from the hospital to home nursing. Further, the nurse has been described as a provider of rehabilitation nursing cooperating with the physiotherapist. The thesis is concerned with the nursing process, it preoccupies with the terminology in the health care, the issue of NANDA, NIC and NOC classifications and the Alliance 3N. Three goals of the thesis were defined: 1. to find out what types of NIC activities are typically used by nurses within the care of patients with total hip replacement. 2. to verify the application of NIC an NOC classifications in the care of patients with total hip replacement. 3. to investigate what sorts of the NOC indicators are typically used by the nurses in the care of patients with total hip replacement. The combination of the quantitative and qualitative research is applied. The four hypotheses were determined in the frame of the quantitative survey: 1. Nursing diagnoses are assessed as not being beneficial by the nurses. 2. Ensuring of tools facilitating the movement is a commonly preferred kind of an intervention by the nurses. 3. The knowledge of NIC and NOC terms is influenced by the previous education. 4. The satisfaction of the nurses with the nursing documentation is influenced by the length of practice. Data was collected by means of the questionnaires. One research query was established for the qualitative research: 1. What is the standpoint of the nurses on the NIC and NOC classifications in the care of the patient with total hip replacement? Data was collected by means of the formed nursing documentation based on the NIC and NOC classifications. The semi-structured interviews were used, as well. H1 remained unconfirmed. H2, H3 and H4 were not statistically validated. The NIC and NOC classifications are generally classified as not being beneficial for the nursing practice by the nurses.
