Abstract The thesis examines the role of a nurse in prevention and treatment of recurrent and chronic rhinitis and possible complications in children. Rhinitis belongs to the most frequent diseases with chronic course in the group of children and adolescents. The number of affected people, particularly among children living in towns and cities is still rising, so sufficient and suitable education of children and parents provided by nurses is very important. Four goals were set in this thesis. The first goal was to examine the role of a nurse in prevention of recurrent and chronic rhinitis. The second goal was to examine the role of a nurse in treatment of recurrent and chronic rhinitis. The third goal focused on examination of the complications nurses most frequently face. The fourth goal was to elaborate an educational standard for nurses working at paediatric wards of hospitals and in surgeries of practitioners for children and adolescents. Three hypotheses were linked to the goals. The first hypothesis assumed that nurses educated parents in prevention of recurrent and chronic rhinitis. The second hypothesis asked whether nurses educated parents and children in treatment and possible complications of recurrent and chronic rhinitis. The third hypothesis said that otitis media, sinusitis and conjunctivitis were the most frequent complications of recurrent and chronic rhinitis. Quantitative research performed by the questionnaire method was used to achieve the goals. An anonymous questionnaire was designed for nurses and parents. The questionnaire for nurses and parents contained 24 questions. 70 questionnaires were distributed among nurses from paediatric wards and 50 returned. The return was 71 %. 60 questionnaires were distributed among nurses in surgeries of practitioners for children and adolescents, 40 returned. The return was 66 %. 50 questionnaires were distributed among parents and 30 returned. The return was 60 %. The data collection was performed in March 2011. The research results showed that most of the nurses educate parents in prevention and treatment of recurrent and chronic rhinitis. The parents confirm the benefit of the education. They consider a talk with a nurse in a surgery the most suitable education form. Education by a nurse has strong influence on parents and children suffering from recurrent and chronic rhinitis. A nurse helps them learn and understand the disease, teaches them how to find a new lifestyle, informs them about prevention and provides information on treatment. We also found that no educational standard dealing with care about children suffering from recurrent and chronic rhinitis existed. We have elaborated the standard and provided it to nurses in surgeries of practitioners for children and adolescents and paediatric wards.
