What treatment did the pediatrician indicate Sean requires at the children's hospital?

• A. Antiviral agents
• B. Humidified oxygen
• C. Cough suppressants
• D. Antibiotic agents

Answer: (B)

Providing humidified oxygen is used when a child’s breathing has not been bringing enough oxygen into the blood. By delivering oxygen in a moist form, the airways stay moisturized, which makes breathing more comfortable and helps the mucociliary system clear secretions more effectively. This supports better oxygen exchange and reduces the work of breathing, which is why this is the appropriate hospital treatment when hypoxemia or respiratory distress is present.

Antiviral agents target specific viruses and don’t directly fix low oxygen levels unless a viral cause is clearly and specifically treated with those drugs. Cough suppressants don’t address the underlying problem of inadequate oxygenation and can mask distress or interfere with airway clearance. Antibiotic agents treat bacterial infections, but they aren’t useful for improving oxygenation unless a bacterial cause is present.
