The gerontological nurse is identifying interventions based upon evidence-based practice. Why are these interventions preferred?
1. They reflect methods that were previously effective for a particular patient.
2. They have been highly effective in the nurse's own practice and experience.
3. They are stated specifically in the policy and procedures manual of the healthcare facility.
4. They show evidence of cause-and-effect between intervention and outcomes.
4
Rationale: Interventions that support evidence-based practice are those that have been tested and have the best chance of establishing a cause-and-effect relationship between the intervention and the desired outcome of care. Methods that were previously effective for a patient may or may not be evidence-based practice interventions.
