It covers more than 50 nursing specialties and includes quick lessons, evidence-based care sheets, CEU modules and research instruments.
Identify keywords for database searching
You will use keywords when conducting a database search. Keywords are words that represent a major concept related to your topic.
Identify the major concepts of your research question or topic. Typically there are between two and four major concepts.
Example: obesity and soda
Find synonyms and related terms:
| Concept 1: Obesity | Concept 2: Soda |
| Body weight | Soft drinks |
| Overweight | Carbonated beverages |
| Obese | Coca-cola |
| Body Mass Index | Sweetened beverages |
| BMI |

TIP: When constructing your search, be concise. Stay away from sentence-like language (such as “effects of soda on contributing to childhood obesity”). The more words you enter, the fewer the results you will get. A search such as “obesity AND soda” will yield more results.
