Often the existence of a phenomenon denoted by a specific concept has been proven, and that the definition corresponds to the object being defined. However, this is often not the case in practice. In nursing, there is a concept of a norm that changes over the years. Moreover, there are diagnostic criteria for diseases, which are also volatile. Thus, despite having a lot of knowledge, decision-making in nursing practice is baffling.

Evidence-based medicine is the bridge between science and nursing practice. Since the specialist is physically unable to study all the necessary information resources to make the right decision, nursing care must be based on well-planned research that meets clear criteria for effectiveness. Thus, in order to make the right decision, it is essential to consider the principles of evidence-based advanced practice.

First of all, it is necessary to formulate a clinical question. According to Johns (2020), the next step is to collect evidence that will provide answers to the questions posed. Thus, an ideal source of information should contain high-quality data, be applicable in clinical practice, contain data on all the benefits and harms of all interventions and drugs, and be easy to use.

An equally important aspect is the critical assessment of the quality of information. Johns (2020) notes that it is not enough to find research or recommendations on an issue; the nurse also needs to evaluate it adequately. The critical question to be answered by the nurse is, “Do I have enough faith in the results of this study to apply its principles to my patients?” (Johns, 2020). The final step is deciding how to use the research findings or recommendations in a particular case. It is one of the most challenging steps, requiring both knowledge and experience from a specialist. At this stage, the nurse weighs the benefits of treatment versus the risk of adverse reactions and makes a choice. Thus, although the theory guide is an evidence-based advanced practice and scholarly inquiry, the nursing practice requires subjective decisions on which the life and health of patients depend.
