What is the independent variable in the context of a study involving nurse specialties?

Anesthesia
Geriatrics
Nurse specialities
Number of nurses

The correct answer is: Nurse specialities

In the context of a study involving nurse specialties, the correct answer is nurse specialties, which serves as the independent variable. This is because the independent variable is the one that is manipulated or categorized to observe its effect on other variables. In this scenario, different nurse specialties might be compared to see how they influence various outcomes, such as patient care quality, job satisfaction, or nursing practices. Anesthesia and geriatrics are specific types of nurse specialties that fall under the broader category of nurse specialties; however, they are not independent variables in this context. The number of nurses could also be considered a dependent variable that may change in response to the variations in nurse specialties, rather than serving as an independent variable itself.
