When the nurse researcher conducts an electronic literature search, the search yields more than 7000 citations for the topic. the researcher should make which of these interpretations of the finding?

The correct answer is "the keywords were not sufficiently narrowed".
In this example, the literature research yielded a great and unmanageable number of citations. It is practically impossible to read all these citations and most probably some of these citations are not relevant to what the nurse researcher is looking for. Therefore, this literature research needs to be conducted again, by narrowing down the focus using more precise terms.
