✓ Correct answer: A. OxygenAnswer: Oxygen Oxygen is most commonly administered to newborns experiencing respiratory distress to ensure they receive adequate oxygenation. Similarly to other drugs, it must be treated with caution and given only for specific indications. These include biochemical criteria (e.g., $$PaO_{2}$$ below 60 mm Hg) and clinical criteria such as respiratory distress, central cyanosis, apnea, asphyxia, hypotonia, and low oxygen saturations. While gases like helium, nitrous oxide, and carbon dioxide can have medical uses, they are not commonly used for respiratory distress in newborns.
