Exercise 10

A nurse proposes that the hospital apply the findings from a re­cent research study that shows that ciients appreciate classical orchestra music and playing it frequently lowers clients' blood pressure. Which aspect of research suggests that it may not be appropriate to implement this as evidence-based practice?
1) All research is flawed.
2) The research would not have taken into consideration the cost of acquiring and playing the music in a hospital.
3) One study would not be sufficient to show that all clients would find orchestral music pleasing.
4) Research cannot demonstrate clients' appreciation of music since research is only appropriate for physiological problems.
