It is important to monitor changes in behaviors or symptoms to determine the efficacy of nursing interventions. In some cases, laboratory results and other diagnostic tests may be required to assess if changes occurred after a nurse intervention. Patients’ feedback is also important in understanding how patients feel about a certain intervention and their experience. It can highlight areas of improvement, or potential benefits not initially recognized. Finaly, nurses should document any observations or assessments they make throughout an intervention. That way progress can be tracked and adjustments made when necessary.
