What forms and sources of evidence will you seek – who or what will you use to help you decide?
Many clients will be highly knowledgeable of their own conditions and this must be respected – especially those with chronic illnesses
May have access to immediate information on the web.

Sources of knowledge: media e.g. newspaper, radio, TV google search, tweets on topic in social media ask colleageues/fellow nurses what they know ask clinicans with specific expertise search health data bases for relevant peer-reviewed research review the topics ina textbook contact advocacy groups

Other consideration: type of question you would ask source chosen should be one that can best answer the question

Professional standrds and codes of practice are resources that all nurses should first seek and always refer to. They provide regulation/direction on many discipline specific topics including the sources of scientific knowledge to support the provision of safe, competent and ethical nursing practice and client care
Terms such a systematic and standardized are typically used to describe the process of scientific (Critical) inquiry.

What sources of knowledge do most front line nurses typically draw on to inform and guide their nursing practice?
Survey from 1999 found that most participants reported drawing most frequently on patient data, their prior care experience and knowledge from their basic nursing education.
Survey in 2005 found most respondents were more comfortable asking their colleagues or searching the internet than using health data bases
In response to disciplinary expectations we’ll need to draw on diverse and up to date evidence base
Integrate newly developing clinical expertise, with what you know about patient’s values AND the best research evidence into the decision making as we plan patient care – EVIDENCE ALONE IS NOT ENOUGH AND
