How often is mouth care given to the unconscious patient?

• A. Every 2 hours
• B. Every 4 hours
• C. Twice daily
• D. Once daily

Answer: (A)

Unconscious patients cannot protect their airway or manage secretions, and their mouths dry out quickly. Keeping the mouth clean and moist reduces irritation, mucosal injury, bacterial growth, and the risk of infection or aspiration pneumonia. Because of these factors, mouth care is performed every two hours to maintain moisture and hygiene. Less frequent care—such as every four hours, twice daily, or once daily—allows dryness and bacteria to build up, increasing the risk of complications.
