• A. Warming the client
• B. Administering oxygen
• C. Giving fluid replacement
• D. Administering thyroid hormone

Answer: (B)

In myxedema coma, the immediate danger is impaired ventilation leading to inadequate oxygen delivery, so addressing breathing takes precedence. Hypoventilation can cause dangerous drops in oxygen levels and buildup of carbon dioxide, which rapidly worsens the patient’s mental status and organ function. Providing supplemental oxygen directly improves arterial oxygenation and buys time for the other interventions to be started safely. Warming, fluid replacement, and thyroid hormone therapy are all important, but they should follow stabilization of the airway and breathing. Correcting hypoxemia is the first step so the brain and other organs aren’t deprived of oxygen while you address temperature, volume status, and definitive thyroid replacement. Administering thyroid hormone is essential for reversing the underlying problem, yet starting it before ensuring adequate oxygenation and airway protection can be risky if the patient’s breathing remains compromised.
