What is the appropriate immediate plan for a patient presenting with singed nasal hairs and surface burns after a natural gas explosion?

In the case of a patient presenting with singed nasal hairs and surface burns after a natural gas explosion, the most appropriate immediate plan is to sedate and intubate. This approach is critical because the inhalation of hot gases or allergens from the explosion can cause airway damage or compromise. Singed nasal hairs indicate that the patient may have been exposed to flames or high heat, which raises the risk of airway swelling and smoke inhalation injuries.

Sedation and intubation ensure that the patient's airway is secured, which is essential for preventing asphyxiation or respiratory failure. Intubation allows for controlled ventilation and protects the airway from further damage during any necessary interventions.

The other options do not adequately address the urgency of potential airway compromise or significant injury caused by the explosion. Administering oral pain medication would be inappropriate due to the risks associated with airway issues. Monitoring and discharging the patient would be highly negligent in a situation where inhalational injuries could lead to rapid deterioration. Providing topical burn ointments might be relevant for surface burns, but it would not take priority over managing the airway in this critical context.
