Final answer:
The accurate information is that descriptive theories describe, relate to, and sometimes predict nursing phenomena. Prescriptive theories do guide specific nursing interventions, contrary to the initial statement.
Step-by-step explanation:
The registered nurse is explaining types of nursing theories, which are essential for guiding nursing practice and research. The question contains several statements that require validation against the accurate understanding of nursing theories:
- Prescriptive theories are actually designed to guide nursing interventions and suggest specific actions for particular situations in healthcare.
- Descriptive theories accurately describe, relate and sometimes predict nursing phenomena.
- Middle-range theories address specific issues or concepts in nursing practice and are neither as broad as grand theories nor as specific as micro-level theories.
- Grand theories provide a broad and abstract overview of nursing as a discipline and are not typically action-oriented or used to test the validity and predictability of a nursing intervention.
Therefore, the accurate information that the registered nurse should provide would be that descriptive theories describe and relate to nursing phenomena, and may also help in prediction.
