MULTIPLE CHOICE

1. The nurse is participating in research that involves the systematic collection of numerical information and the analysis of that information using statistical procedures. This type of research is known as:
a.
quantitative research.
c.
evaluative research.
b.
qualitative research.
d.
exploratory research.

ANS: A
Quantitative research is the systematic collection of numerical information and the analysis of the information using statistical procedures. Qualitative research is the systematic collection and analysis of more subjective narrative materials using procedures in which there tends to be a minimum of researcher-imposed control. Evaluative research is the systematic investigation of how well a program, practice, or policy is working. Exploratory research is the preliminary investigation designed to develop or refine hypotheses or to test the data collection methods.

2. The Quality Improvement Committee within a hospital is utilizing evaluative research to do which of the following?
a.
Investigate the possibility of undertaking a research study
b.
Compare an intervention with a group versus a control group
c.
Describe a situation, problem, or phenomenon in a community
d.
Measure the effectiveness of a program, practice, or policy

ANS: D
Evaluative research measures the effectiveness of a program, practice, or policy. Describing a situation, problem, or phenomenon in a community is the definition of research.
