To assess the gag reflex, a nurse typically uses a tongue depressor or a similar instrument: 1. Explain the procedure to the patient to reduce anxiety. 2. Position the patient in a semi-upright position to prevent aspiration. 3. Gently touch the back of the throat, the roof of the mouth, or the back of the tongue. 4. Observe for a reaction, such as gagging or coughing, which indicates an intact reflex.
