Correct answer: B. Burning substernal chest pain with dry cough
- A. Mild nasal dryness after one hour
- B. Burning substernal chest pain with dry cough

A dry cough, substernal discomfort and worsening respiratory symptoms may occur with prolonged exposure to high oxygen concentrations. Nasal dryness is usually related to inadequate humidification, not oxygen toxicity.
