To apply a gait belt correctly: 1. Explain the procedure to the patient to gain their cooperation and reduce anxiety. 2. Place the belt around the patient's waist, over their clothing, and fasten the buckle securely. 3. Ensure the belt is snug but not too tight, allowing you to fit two fingers between the belt and the patient's body. 4. Always stand close to the patient and use a proper grip on the belt, avoiding twisting or pulling on it excessively.
