Public Health Nursing Practice Exam

What type of data is being collected when a nurse interviews key informants about seat belt usage?

1. Quantitative

2. Qualitative

3. Focus-groups

4. Survey

The correct answer is: Qualitative

The correct answer identifies the collection of qualitative data through the interview of key informants. Qualitative data is focused on understanding human behavior, experiences, and the meanings people place on those experiences. In this case, when a nurse interviews individuals to gather insights about seat belt usage, they capture personal attitudes, thoughts, and feelings toward the subject matter. This type of data allows for a deeper understanding of the social, cultural, or situational factors influencing seat belt usage. Quantitative data, on the other hand, consists of numerical values and statistical analysis, which is not the primary focus in this scenario. While focus groups might seem relevant as a method of collecting qualitative data, they specifically involve group discussions rather than individual interviews. Additionally, surveys gather quantitative or qualitative data through structured questions, but the interview of key informants primarily leans toward the qualitative aspect due to the open-ended nature of the dialogue and the depth of insight sought.
