Nursing intervention is any treatment or action performed by a nurse based on clinical judgment and evidence-based nursing knowledge to improve patient outcomes. There are three types of nursing interventions: nurse-initiated, physician-initiated, and collaborative. A nurse-initiated intervention is a self-directed action based on a scientific rationale related to nursing diagnosis. For example, providing health education on nutritious meals with low carbohydrates to obese patients. A physician-initiated intervention is a treatment that is initiated by a physician based on a medical diagnosis but is performed by a nurse. For example, nurses administer medication based on a physician's order. A collaborative intervention is when a nurse performs a procedure recommended by other healthcare professionals. For instance, the nurse advises the patient to take a low-salt diet as per the dietician's order.
