In a child with signs of respiratory distress and hypoxemia, which action should be prioritized?

• A. Administer oxygen first
• B. Begin IV fluids first
• C. Defibrillate first
• D. Administer antibiotics first

Answer: (A)

In a child with respiratory distress and hypoxemia, the immediate goal is to restore adequate oxygen delivery to tissues. Hypoxemia worsens organ function quickly in kids, so providing supplemental oxygen takes priority to improve oxygen saturation and ease the work of breathing. Start with a suitable oxygen delivery method—humidified oxygen via nasal cannula or mask, progressing to a non-rebreather or bag-valve-mask with high flow if needed—while you monitor SpO2 and breathing effort. Once oxygenation is stabilized, you can address other concerns such as airway patency, ventilation support if the child tires, or signs of shock or infection.

IV fluids, while important if there is true shock, do not fix low oxygen levels and should not delay oxygen therapy. Defibrillation is reserved for cardiac arrest or certain life-threatening arrhythmias, not isolated respiratory distress. Antibiotics may be necessary for infection, but they do not provide immediate relief of hypoxemia and should not precede stabilization of oxygenation.
