Introduction: The investigative techniques in the field of surgery are divided into two main groups named endoscopic and imaging methods. The main difference between them is that endoscopic methods are used for inspection of internal hollow organs, tissue biopsy, as well as treatment, while imaging methods are used for creating images of the body and internal organs using x-ray, ultrasound and magnetic resonance imaging. Purpose: The purpose of the diploma work is to desribe both methods, using scientific literature. The main focus is the role of the nurse in each type of investigation technique and what are the appropriate approaches to the patient based on their condition, age, gender and other factors. Methods: We used descriptive methods based on literature review in English and Slovenian language, we used a timeline from 2013 to 2019 in the databases CINAHL, Medline (PubMed) and COBISS.SI. Results: It’s nurses job to prepare patients for medical examinations. This means that the patients must be physically and mentally prepared for the following interventions. Also every patient must be acquainted with all the necessary information about procedure. In the field of imaging examination methods nurse must have a good knowledge of ionizing radiation protection and all aspects of safety, including in safety of the prevention of infections.
