Different disciplines require different citation styles. Examples are APA, MLA, Chicago, Turabian, etc. APA from the American Psychological Association is the style you will use in Nursing.
Many online sources (including anything found the library's Quick Search) has a tool for finding the resource's citation. Look for buttons that either say "Cite," "Citation," or are just an icon of quotation marks (").
TAMU-CC's Writing Center also points to this source for help in citing.
If you just need a quick reminder, here's a rundown of the basic guidelines. Visit the Purdue Online Writing Lab or the CASA Writing Center for more detailed examples.
