What is the recommended treatment for a croup-like cough in the BLS protocol?

• A. Oral rehydration
• B. Aerosolized saline 5 mL via O2-powered nebulizer/mask MR PRN
• C. Humidified air only
• D. No treatment required

Answer: (B)

When a croup-like cough is suspected, the goal in the BLS setting is to humidify and moisten the airway to ease swelling and secretions. Administering a small amount of saline via an oxygen-powered nebulizer with a mask delivers a fine mist that hydrates the airway surfaces and helps loosen mucus, making breathing easier; do this as needed. This approach directly addresses airway hydration and mucus clearance, which is why it’s the recommended treatment. Oral rehydration doesn’t address the airway issue, humidified air alone provides less targeted relief, and doing nothing misses an opportunity to improve symptoms.
