Nursing Research

1. Nursing research is a systematic inquiry that validates and enhances existing nursing knowledge and generates new information to establish nursing theories and directly impact clinical practice. 2. A research agenda provides a structured way to prioritize issues and topics to study within a given time period, such as the National Unified Health Research Agenda that guides Philippine health research. 3. Literature reviews summarize and critically analyze existing research on a topic to identify key concepts and differences and show how a new study relates to the broader field of research.

• Functional maintenance/improvement of physical
