A professional nurse is searching for information on confidentiality in nursing in a database. The nurse enters two key words (confidentiality, nursing) into the search interface of the database. The nurse retrieves too many records and does not have much time to review all the records. Which of the following Boolean Operators would be appropriate for the nurse to use with the key words to narrow the search?
Correct answer
C
Rationale
The 'AND' operator narrows the search by retrieving only records that contain both keywords, 'confidentiality' and 'nursing,' thus reducing the number of results. 'Maybe' is not a valid Boolean operator. 'NOT' excludes records containing a specific term, which could unintentionally exclude relevant records. 'OR' broadens the search by retrieving records that contain either keyword, leading to more results.
