Chronic bronchitis interventions: Which intervention is most effective for thinning secretions and improving clearance?

• A. Guaifenesin
• B. Humidifier
• C. Abdominal breathing using Huff method
• D. Increase fluids to 2-3 L daily

Answer: (D)

Thinning thick secretions to improve clearance hinges on keeping mucus well hydrated. When you drink enough fluids, the mucus becomes less viscous, making it easier to expectorate and for ciliary action to move it out of the airways. Increasing fluids to about 2–3 liters daily directly targets mucus viscosity, so secretions are easier to cough up and clear, which is especially helpful in chronic bronchitis where mucus production is increased. Other options offer supportive benefits—guaifenesin may help some people, humidifiers add moisture to the air, and airway clearance techniques like Huff breathing aid removal of secretions—but they’re not as reliably effective at thinning mucus as adequate hydration. So, maintaining higher fluid intake is the most effective way to thin secretions and improve clearance.
