A nurse has observed that quite a few patients on the unit develop pressure sores while in the agency. The nurse wonders whether there are better preventive measures than are currently being used and wishes to find the best evidence for perhaps changing at least one intervention. What should the nurse do next?
1) Identify a clinical nursing problem.
2) Formulate a PICOT question on the topic.
3) Search the nursing literature.
4) Evaluate the quality of the research in the literature.
