Q. How do I make an APA citation for a Quick Lesson from CINAHL?

COM Library does not have Quick Lessons in its version of CINAHL, so we cannot be certain of their content or the proper citation format for them.  General advice for citing online documents states to include as much information as possible.  The general format for making APA citations for materials found in academic databases is:

Author, A. A., & Author, B. B. (Date of publication). Title of article. Title of Journal, volume number, page range. Retrieved from http://www.someaddress.com/full/url/

Since Quick Lessons do not have volumes or page numbers, you would omit that section.  The citation would look something like this:

Riviera, D. N. (2013). Hypotension. CINAHL Nursing guide.
