Which option represents a single qualitative study?

• A. Systematic review of descriptive studies
• B. Single qualitative study
• C. Randomized controlled trial
• D. Meta-analysis

Answer: (B)

Understanding study designs in evidence-based nursing development means distinguishing primary studies from syntheses and recognizing qualitative versus quantitative approaches. A single qualitative study is an in-depth investigation conducted as one research project, using methods like interviews, focus groups, or observations to explore experiences, meanings, or social processes. The analysis yields rich, contextual insights and themes from a specific context, without pooling data across multiple studies. This is why it best fits as a single qualitative study: it reflects one qualitative investigation reporting its findings. The other options are different kinds of evidence synthesis or quantitative research. A systematic review of descriptive studies combines findings from multiple descriptive studies, not a single study. A randomized controlled trial uses quantitative, experimental methods to test interventions. A meta-analysis statistically combines results from several studies, again not a single study.
