When brushing the tongue of an unconscious patient, what must the nurse avoid?

When brushing the tongue of an unconscious patient, it is essential for the nurse to avoid stimulating the gag reflex. This is particularly important because an unconscious patient does not have the protective reflexes necessary to clear their airway. Stimulating the gag reflex in this situation can lead to aspiration, where food, fluid, or debris enters the airway, potentially causing choking or respiratory complications.

Maintaining an open and clear airway is a priority when caring for unconscious individuals, and any action that could lead to gagging must be approached with caution. Meanwhile, the other actions, such as dislodging bacteria, moistening the oral mucosa, and using suction, are typically beneficial for the patient's oral hygiene and health. Proper management of the oral cavity can prevent complications like pneumonia, which is often associated with poor oral hygiene in unconscious patients.
