Assignment Help: 2303, Evidence Based Discovery

GN2303 Assignment #1, Identifying the Evidence Base in Nursing Point of Care Resources 

The assignment asks you to evaluate the references used in the development of a selected evidence summary, and for each reference state whether it is a Primary or Secondary Source, state the Level of Evidence based on the evidence pyramid, and substantiation of the level of evidence.

It is not a library scavenger hunt whereby you necessarily are to locate the full text of each reference. Rather, you are to view a reference, follow up if possible by looking at the book, the website, or an citation in a database, or possibly the full text.  You might have to evaluate the level of evidence as to whether it is a primary or secondary source just on the basis on the reference citation itself and the information given (the year, the organization, etc).  


  • If you DO have a citation to a scholarly article, look it up in one of the health sciences databases like PubMed or CINAHL.  If you locate it, notice the "publication type," an indication of the level of evidence.  Is it an original (primary) study?  Or a secondary synthesis?
  • If you have a web link, even a partial web link, evaluate the strength and quality of the evidence based on what you find there.  What audience is it aimed at? Consumers or professionals? Who are the authors? 
  • Use the evidence pyramid supplied by your professors.  Often it is only by process of elimination that you can make a determination of whether it fits into a category or appears to be the opinion of "experts."
